+     * <p>For some YUV reprocessing use cases, the application may choose to filter the original
+     * output frames to effectively reduce the noise to the same level as a frame that was
+     * captured with longer exposure time. To be more specific, assuming the original captured
+     * images were captured with a sensitivity of S and an exposure time of T, the model in
+     * the camera device is that the amount of noise in the image would be approximately what
+     * would be expected if the original capture parameters had been a sensitivity of
+     * S/effectiveExposureFactor and an exposure time of T*effectiveExposureFactor, rather
+     * than S and T respectively. If the captured images were processed by the application
+     * before being sent for reprocessing, then the application may have used image processing
+     * algorithms and/or multi-frame image fusion to reduce the noise in the
+     * application-processed images (input images). By using the effectiveExposureFactor
+     * control, the application can communicate to the camera device the actual noise level
+     * improvement in the application-processed image. With this information, the camera
+     * device can select appropriate noise reduction and edge enhancement parameters to avoid
+     * excessive noise reduction ({@link CaptureRequest#NOISE_REDUCTION_MODE android.noiseReduction.mode}) and insufficient edge
+     * enhancement ({@link CaptureRequest#EDGE_MODE android.edge.mode}) being applied to the reprocessed frames.</p>
+     * <p>For example, for multi-frame image fusion use case, the application may fuse
+     * multiple output frames together to a final frame for reprocessing. When N image are
+     * fused into 1 image for reprocessing, the exposure time increase factor could be up to
+     * square root of N (based on a simple photon shot noise model). The camera device will
+     * adjust the reprocessing noise reduction and edge enhancement parameters accordingly to
+     * produce the best quality images.</p>
+     * <p>This is relative factor, 1.0 indicates the application hasn't processed the input
+     * buffer in a way that affects its effective exposure time.</p>
+     * <p>This control is only effective for YUV reprocessing capture request. For noise
+     * reduction reprocessing, it is only effective when <code>{@link CaptureRequest#NOISE_REDUCTION_MODE android.noiseReduction.mode} != OFF</code>.

+
+<p>A custom transition enables you to create an animation that is not available from any of
+the built-in transition classes. For example, you can define a custom transition that turns
+the foreground color of text and input fields to gray to indicate that the fields are disabled
+in the new screen. This type of change helps users see the fields you disabled.</p>
+
+<p>A custom transition, like one of the built-in transition types, applies animations to
+child views of both the starting and ending scenes. Unlike built-in transition types,
+however, you have to provide the code that captures property values and generates animations.
+You may also want to define a subset of target views for your animation.</p>
+
+<p>This lesson teaches you to capture property values and generate animations to create
+custom transitions.</p>
+
+
+
+<h2 id="Extend">Extend the Transition Class</h2>
+
+<p>To create a custom transition, add a class to your project that extends the {@link
+android.transition.Transition} class and override the methods shown in the following snippet:</p>
+
+<pre>
+public class CustomTransition extends Transition {
+
+    &#64;Override
+    public void captureStartValues(TransitionValues values) {}
+
+    &#64;Override
+    public void captureEndValues(TransitionValues values) {}
+
+    &#64;Override
+    public Animator createAnimator(ViewGroup sceneRoot,
+                                   TransitionValues startValues,
+                                   TransitionValues endValues) {}
+}
+</pre>
+
+<p>The following sections explain how to override these methods.</p>
+
+
+
+<h2 id="CaptureProperties">Capture View Property Values</h2>
+
+<p>Transition animations use the property animation system described in
+<a href="{@docRoot}guide/topics/graphics/prop-animation.html">Property Animation</a>. Property
+animations change a view property between a starting and ending value over a specified
+period of time, so the framework needs to have both the starting and ending value of
+the property to construct the animation.</p>
+
+<p>However, a property animation usually needs only a small subset of all the view's property
+values. For example, a color animation needs color property values, while a movement
+animation needs position property values. Since the property values needed for an animation
+are specific to a transition, the transitions framework does not provide every property value
+to a transition. Instead, the framework invokes callback methods that allow a transition to
+capture only the property values it needs and store them in the framework.</p>
+
+
+<h3 id="StartingValues">Capturing Starting Values</h3>
+
+<p>To pass the starting view values to the framework, implement the
+{@link android.transition.Transition#captureStartValues captureStartValues(transitionValues)}
+method. The framework calls this method for every view in the starting scene. The method
+argument is a {@link android.transition.TransitionValues} object that contains a reference
+to the view and a {@link java.util.Map} instance in which you can store the view values you
+want. In your implementation, retrieve these property values and pass them back to the
+framework by storing them in the map.</p>
+
+<p>To ensure that the key for a property value does not conflict with other {@link
+android.transition.TransitionValues} keys, use the following naming scheme:</p>
+
+<pre>
+package_name:transition_name:property_name
+</pre>
+
+<p>The following snippet shows an implementation of the {@link
+android.transition.Transition#captureStartValues captureStartValues()} method:</p>
+
+<pre>
+public class CustomTransition extends Transition {
+
+    // Define a key for storing a property value in
+    // TransitionValues.values with the syntax
+    // package_name:transition_class:property_name to avoid collisions
+    private static final String PROPNAME_BACKGROUND =
+            "com.example.android.customtransition:CustomTransition:background";
+
+    &#64;Override
+    public void captureStartValues(TransitionValues transitionValues) {
+        // Call the convenience method captureValues
+        captureValues(transitionValues);
+    }
+
+
+    // For the view in transitionValues.view, get the values you
+    // want and put them in transitionValues.values
+    private void captureValues(TransitionValues transitionValues) {
+        // Get a reference to the view
+        View view = transitionValues.view;
+        // Store its background property in the values map
+        transitionValues.values.put(PROPNAME_BACKGROUND, view.getBackground());
+    }
+    ...
+}
+</pre>
+
+
+<h3 id="EndingValues">Capture Ending Values</h3>
+
+<p>The framework calls the {@link android.transition.Transition#captureEndValues} method
+once for every target view in the ending scene. In all other respects, {@link
+android.transition.Transition#captureEndValues captureEndValues()} works the same as {@link
+android.transition.Transition#captureStartValues captureStartValues()}.</p>
+
+<p>The following code snippet shows an implementation of the {@link
+android.transition.Transition#captureEndValues captureEndValues()} method:</p>
+
+<pre>
+&#64;Override
+public void captureEndValues(TransitionValues transitionValues) {
+    captureValues(transitionValues);
+}
+</pre>
+
+<p>In this example, both the {@link android.transition.Transition#captureStartValues
+captureStartValues()} and {@link android.transition.Transition#captureEndValues captureEndValues()}
+methods invoke <code>captureValues()</code> to retrieve and store values. The view property
+that <code>captureValues()</code> retrieves is the same, but it has different values in the
+starting and ending scenes. The framework maintains separate maps for the starting and ending
+states of a view.</p>
+
+
+
+<h2 id="CreateAnimator">Create a Custom Animator</h2>
+
+<p>To animate the changes to a view between its state in the starting scene and its state in
+the ending scene, you provide an animator by overriding the {@link
+android.transition.Transition#createAnimator createAnimator()} method. When the
+framework calls this method, it passes in the scene root view and the {@link
+android.transition.TransitionValues} objects that contain the starting and ending values
+you captured.</p>
+
+<p>The number of times the framework calls the {@link
+android.transition.Transition#createAnimator createAnimator()} method depends on the changes that
+occur between the starting and ending scenes. For example, consider a fade out/fade in animation
+implemented as a custom transition. If the starting scene has five targets of which two are
+removed from the ending scene, and the ending scene has the three targets from the starting
+scene plus a new target, then the framework calls {@link
+android.transition.Transition#createAnimator createAnimator()} six times: three of the calls
+animate the fading out and fading in of the targets that stay in both scene objects; two more calls
+animate the fading out of the targets removed from the ending scene; and one call
+animates the fading in of the new target in the ending scene.</p>
+
+<p>For target views that exist on both the starting and ending scenes, the framework provides
+a {@link android.transition.TransitionValues} object for both the <code>startValues</code> and
+<code>endValues</code> arguments. For target views that only exist in the starting or the
+ending scene, the framework provides a {@link android.transition.TransitionValues} object
+for the corresponding argument and <code>null</code> for the other.</p>
+
+<p>To implement the {@link android.transition.Transition#createAnimator} method when you create
+a custom transition, use the view property values you captured to create an {@link
+android.animation.Animator} object and return it to the framework. For an example implementation,
+see the <a
+href="{@docRoot}samples/CustomTransition/src/com.example.android.customtransition/ChangeColor.html">
+<code>ChangeColor</code></a> class in the <a href="{@docRoot}samples/CustomTransition/index.html">
+CustomTransition</a> sample. For more information about property animators, see
+<a href="{@docRoot}guide/topics/graphics/prop-animation.html">Property Animation</a>.</p>
+
+
+
+<h2 id="Apply">Apply a Custom Transition</h2>
+
+<p>Custom transitions work the same as built-in transitions. You can apply a custom transition
+using a transition manager, as described in <a
+href="{@docRoot}training/transitions/transitions.html#Apply">Applying a Transition</a>.</p>

+<p>The user interface of an activity often changes in response to user input and other events.
+For example, an activity that contains a form where users can type search queries can hide
+the form when the user submits it and show a list of search results in its place.</p>
+
+<p>To provide visual continuity in these situations, you can animate changes between
+different view hierarchies in your user interface. These animations give users feedback on
+their actions and help them learn how your app works.</p>
+
+<p>Android includes the <em>transitions framework</em>, which enables you to easily
+animate changes between two view hierarchies. The framework animates the views at runtime by
+changing some of their property values over time. The framework includes built-in animations
+for common effects and lets you create custom animations and transition lifecycle callbacks.</p>
+
+<p>This class teaches you to use the built-in animations in the transitions framework to
+animate changes between view hierarchies. This class also covers how to create custom
+animations.</p>
+
+<p class="note"><strong>Note:</strong> For Android versions earlier than 4.4.2 (API level 19)
+but greater than or equal to Android 4.0 (API level 14), use the <code>animateLayoutChanges</code>
+attribute to animate layouts. To learn more, see

+<p>Animating your app's user interface provides more than just visual appeal. Animations
+highlight changes and provide visual cues that help users learn how your app works.</p>
+
+<p>To help you animate a change between one view hierarchy and another, Android provides the
+transitions framework. This framework applies one or more animations to all the views in the
+hierarchies as it changes between them.</p>
+
+<p>The framework has the following features:</p>
+
+<dl>
+<dt><em>Group-level animations</em></dt>
+<dd>Applies one or more animation effects to all of the views in a view hierarchy.</dd>
+<dt><em>Transition-based animation</em></dt>
+<dd>Runs animations based on the changes between starting and ending view property values.</dd>
+<dt><em>Built-in animations</em></dt>
+<dd>Includes predefined animations for common effects such as fade out or movement.</dd>

+
+
+
+<h2 id="Overview">Overview</h2>
+
+<p>The example in Figure 1 shows how an animation provides visual cues to help the user. As the
+app changes from its search entry screen to its search results screen, it fades out views that
+are no longer in use and fades in new views.</p>
+
+<p>This animation is an example of using the transitions framework. The framework
+animates changes to all the views in two view hierarchies. A view hierarchy can be as simple
+as a single view or as complex as a {@link android.view.ViewGroup} containing an elaborate
+tree of views. The framework animates each view by changing one or more of its property values
+over time between the initial or <em>starting</em> view hierarchy and the final or <em>ending</em>
+view hierarchy.</p>
+
+<p>The transitions framework works in parallel with view hierarchies and animations. The
+purpose of the framework is to store the state of view hierarchies, change between these
+hierarchies in order to modify the appearance of the device screen, and animate the change by
+storing and applying animation definitions.</p>
+
+<p>The diagram in Figure 2 illustrates the relationship between view hierarchies, framework
+objects, and animations:</p>
+
+<!-- Figure 2 - diagram -->
+<img src="{@docRoot}images/transitions/transitions_diagram.png"
+     width="506" height="234" alt="" style="margin-top:7px" />
+<p class="img-caption"><strong>Figure 2.</strong> Relationships in the transitions framework.</p>
+
+<p>The transitions framework provides abstractions for scenes, transitions, and transition
+managers. These are described in detail in the following sections. To use the framework, you
+create scenes for the view hierarchies in your app that you plan to change between. Next, you
+create a transition for each animation you want to use. To start the animation between two
+view hierarchies, you use a transition manager specifying the transition to use and the ending
+scene. This procedure is described in detail in the remaining lessons in this class.</p>
+
+
+
+<h2 id="Scenes">Scenes</h2>
+
+<p>A scene stores the state of a view hierarchy, including all its views and their property
+values. A view hierarchy can be a simple view or a complex tree of views and child layouts.
+Storing the view hierarchy state in a scene enables you to transition into that state from
+another scene. The framework provides the {@link android.transition.Scene} class to represent
+a scene.</p>
+
+<p>The transitions framework lets you create scenes from layout resource files or from
+{@link android.view.ViewGroup} objects in your code. Creating a scene in your code is useful
+if you generated a view hierarchy dynamically or if you are modifying it at runtime.</p>
+
+<p>In most cases, you do not create a starting scene explicitly. If you have applied a
+transition, the framework uses the previous ending scene as the starting scene for any
+subsequent transitions. If you have not applied a transition, the framework collects information
+about the views from the current state of the screen.</p>
+
+<p>A scene can also define its own actions that run when you make a scene change. For example,
+this feature is useful for cleaning up view settings after you transition to a scene.</p>
+
+<p>In addition to the view hierarchy and its property values, a scene also stores a reference
+to the parent of the view hierarchy. This root view is called a <strong>scene root</strong>.
+Changes to the scene and animations that affect the scene occur within the scene root.</p>
+
+<p>To learn how to create scenes, see
+<a href="{@docRoot}training/transitions/scenes.html">Creating a Scene</a>.</p>
+
+
+
+<h2 id="Transitions">Transitions</h2>
+
+<p>In the transitions framework, animations create a series of frames that depict a change
+between the view hierarchies in the starting and ending scenes. Information about the animation
+is stored in a {@link android.transition.Transition} object. To run the animation, you apply the
+transition using a {@link android.transition.TransitionManager} instance. The framework can
+transition between two different scenes or transition to a different state for the current
+scene.</p>
+
+<p>The framework includes a set of built-in transitions for commonly-used animation effects,
+such as fading and resizing views. You can also define your own custom transitions to create
+an animation effect using the APIs in the animations framework. The transitions framework also
+enables you to combine different animation effects in a transition set that contains a group
+of individual built-in or custom transitions.</p>
+
+<p>The transition lifecycle is similar to the activity lifecycle, and it represents the
+transition states that the framework monitors between the start and the completion of an
+animation. At important lifecycle states, the framework invokes callback methods that you can
+implement to make adjustments to your user interface at different phases of the transition.</p>
+
+<p>To learn more about transitions, see
+<a href="{@docRoot}training/transitions/transitions.html">Applying a Transition</a> and
+<a href="{@docRoot}training/transitions/custom-transitions.html">Creating Custom
+Transitions</a>.</p>
+
+
+
+<h2 id="Limitations">Limitations</h2>
+
+<p>This section lists some known limitations of the transitions framework:</p>
+
+<ul>
+<li>Animations applied to a {@link android.view.SurfaceView} may not appear correctly.
+{@link android.view.SurfaceView} instances are updated from a non-UI thread, so the updates
+may be out of sync with the animations of other views.</li>
+<li>Some specific transition types may not produce the desired animation effect when applied
+to a {@link android.view.TextureView}.</li>
+<li>Classes that extend {@link android.widget.AdapterView}, such as
+{@link android.widget.ListView}, manage their child views in ways that are incompatible with
+the transitions framework. If you try to animate a view based on
+{@link android.widget.AdapterView}, the device display may hang.</li>
+<li>If you try to resize a {@link android.widget.TextView} with an animation, the text will
+pop to a new location before the object has completely resized. To avoid this problem, do not
+animate the resizing of views that contain text.</li>
+</ul>

+
+<p>Scenes store the state of a view hierarchy, including all its views and their property
+values. The transitions framework can run animations between a starting and an ending scene.
+The starting scene is often determined automatically from the current state of the user
+interface. For the ending scene, the framework enables you to create a scene from a layout
+resource file or from a group of views in your code.</p>
+
+<p>This lesson shows you how to create scenes in your app and how to define scene actions.
+The next lesson shows you how to transition between two scenes.</p>
+
+<p class="note"><strong>Note:</strong> The framework can animate changes in a single view
+hierarchy without using scenes, as described in
+<a href="{@docRoot}training/transitions/transitions.html#NoScenes">Apply a Transition Without
+Scenes</a>. However, understanding this lesson is essential to work with transitions.</p>
+
+
+
+<h2 id="FromLayout">Create a Scene From a Layout Resource</h2>
+
+<p>You can create a {@link android.transition.Scene} instance directly from a layout resource
+file. Use this technique when the view hierarchy in the file is mostly static. The resulting
+scene represents the state of the view hierarchy at the time you created the
+{@link android.transition.Scene} instance. If you change the view hierarchy, you have to
+recreate the scene. The framework creates the scene from the entire view hierarchy in the
+file; you can not create a scene from part of a layout file.</p>
+
+<p>To create a {@link android.transition.Scene} instance from a layout resource file, retrieve
+the scene root from your layout as a {@link android.view.ViewGroup} instance and then call the
+{@link android.transition.Scene#getSceneForLayout Scene.getSceneForLayout()} method with the
+scene root and the resource ID of the layout file that contains the view hierarchy for the
+scene.</p>
+
+<h3>Define Layouts for Scenes</h3>
+
+<p>The code snippets in the rest of this section show you how to create two different scenes
+with the same scene root element. The snippets also demonstrate that you can load multiple
+unrelated {@link android.transition.Scene} objects without implying that they are related to
+each other.</p>
+
+<p>The example consists of the following layout definitions:</p>
+
+<ul>
+<li>The main layout of an activity with a text label and a child layout.</li>
+<li>A relative layout for the first scene with two text fields.</li>
+<li>A relative layout for the second scene with the same two text fields in different order.</li>
+</ul>
+
+<p>The example is designed so that all of the animation occurs within the child layout of the
+main layout for the activity. The text label in the main layout remains static.</p>
+
+<p>The main layout for the activity is defined as follows:</p>
+
+<p class="code-caption">res/layout/activity_main.xml</p>
+
+<pre>
+&lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
+    android:id="@+id/master_layout">
+    &lt;TextView
+        android:id="@+id/title"
+        ...
+        android:text="Title"/>
+    &lt;FrameLayout
+        android:id="@+id/scene_root">
+        &lt;include layout="@layout/a_scene" />
+    &lt;/FrameLayout>
+&lt;/LinearLayout>
+</pre>
+
+<p>This layout definition contains a text field and a child layout for the scene root. The
+layout for the first scene is included in the main layout file. This allows the app to display
+it as part of the initial user interface and also to load it into a scene, since the framework
+can load only a whole layout file into a scene.</p>
+
+<p>The layout for the first scene is defined as follows:</p>
+
+<p class="code-caption">res/layout/a_scene.xml</p>
+
+<pre>
+&lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
+    android:id="@+id/scene_container"
+    android:layout_width="match_parent"
+    android:layout_height="match_parent" >
+    &lt;TextView
+        android:id="@+id/text_view1
+        android:text="Text Line 1" />
+    &lt;TextView
+        android:id="@+id/text_view2
+        android:text="Text Line 2" />
+&lt;/RelativeLayout>
+</pre>
+
+<p>The layout for the second scene contains the same two text fields (with the same IDs)
+placed in a different order and is defined as follows:</p>
+
+<p class="code-caption">res/layout/another_scene.xml</p>
+
+<pre>
+&lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
+    android:id="@+id/scene_container"
+    android:layout_width="match_parent"
+    android:layout_height="match_parent" >
+    &lt;TextView
+        android:id="@+id/text_view2
+        android:text="Text Line 2" />
+    &lt;TextView
+        android:id="@+id/text_view1
+        android:text="Text Line 1" />
+&lt;/RelativeLayout>
+</pre>
+
+<h3>Generate Scenes from Layouts</h3>
+
+<p>After you create definitions for the two relative layouts, you can obtain an scene for
+each of them. This enables you to later transition between the two UI configurations.
+To obtain a scene, you need a reference to the scene root and the layout resource ID.</p>
+
+<p>The following code snippet shows you how to get a reference to the scene root and create
+two {@link android.transition.Scene} objects from the layout files:</p>
+
+<pre>
+Scene mAScene;
+Scene mAnotherScene;
+
+// Create the scene root for the scenes in this app
+mSceneRoot = (ViewGroup) findViewById(R.id.scene_root);
+
+// Create the scenes
+mAScene = Scene.getSceneForLayout(mSceneRoot, R.layout.a_scene, this);
+mAnotherScene =
+    Scene.getSceneForLayout(mSceneRoot, R.layout.another_scene, this);
+</pre>
+
+<p>In the app, there are now two {@link android.transition.Scene} objects based on view
+hierarchies. Both scenes use the scene root defined by the
+{@link android.widget.FrameLayout} element in <code>res/layout/activity_main.xml</code>.</p>
+
+
+
+<h2 id="FromCode">Create a Scene in Your Code</h2>
+
+<p>You can also create a {@link android.transition.Scene} instance in your code from a
+{@link android.view.ViewGroup} object. Use this technique when you modify the view hierarchies
+directly in your code or when you generate them dynamically.</p>
+
+<p>To create a scene from a view hierarchy in your code, use the
+{@link android.transition.Scene#Scene(android.view.ViewGroup, android.view.View) Scene(sceneRoot, viewHierarchy)}
+constructor. Calling this constructor is equivalent to calling the
+{@link android.transition.Scene#getSceneForLayout Scene.getSceneForLayout()} method when you
+have already inflated a layout file.</p>
+
+<p>The following code snippet demonstrates how to create a {@link android.transition.Scene}
+instance from the scene root element and the view hierarchy for the scene in your code:</p>
+
+<pre>
+Scene mScene;
+
+// Obtain the scene root element
+mSceneRoot = (ViewGroup) mSomeLayoutElement;
+
+// Obtain the view hierarchy to add as a child of
+// the scene root when this scene is entered
+mViewHierarchy = (ViewGroup) someOtherLayoutElement;
+
+// Create a scene
+mScene = new Scene(mSceneRoot, mViewHierarchy);
+</pre>
+
+
+
+<h2 id="Actions">Create Scene Actions</h2>
+
+<p>The framework enables you to define custom scene actions that the system runs when entering
+or exiting a scene. In many cases, defining custom scene actions is not necessary, since the
+framework animates the change between scenes automatically.</p>
+
+<p>Scene actions are useful for handling these cases:</p>
+
+<ul>
+<li>Animate views that are not in the same hierarchy. You can animate views for both the
+starting and ending scenes using exit and entry scene actions.</li>
+<li>Animate views that the transitions framework cannot animate automatically, such as
+{@link android.widget.ListView} objects. For more information, see
+<a href="{@docRoot}training/transitions/overview.html#Limitations">Limitations</a>.</li>
+</ul>
+
+<p>To provide custom scene actions, define your actions as {@link java.lang.Runnable} objects
+and pass them to the {@link android.transition.Scene#setExitAction Scene.setExitAction()} or
+{@link android.transition.Scene#setEnterAction Scene.setEnterAction()} methods. The framework
+calls the {@link android.transition.Scene#setExitAction setExitAction()} method on the starting
+scene before running the transition animation and the {@link
+android.transition.Scene#setEnterAction setEnterAction()} method on the ending scene after
+running the transition animation.</p>
+
+<p class="note"><strong>Note:</strong> Do not use scene actions to pass data between views in
+the starting and ending scenes. For more information, see
+<a href="{@docRoot}training/transitions/transitions.html#Callbacks">Defining Transition
+Lifecycle Callbacks</a>.</p>

+that defines an animation. The framework enables you to specify a built-in transition in a
+resource file and inflate it in your code or to create an instance of a built-in transition
+directly in your code.</p>

+<h3 id="FromFile">Create a transition instance from a resource file</h3>
+
+<p>This technique enables you to modify your transition definition without having to change
+the code of your activity. This technique is also useful to separate complex transition
+definitions from your application code, as shown in <a href="#Multiple">Specify Multiple
+Transitions</a>.</p>
+
+<p>To specify a built-in transition in a resource file, follow these steps:</p>
+
+<ol>
+<li>Add the <code>res/transition/</code> directory to your project.</li>
+<li>Create a new XML resource file inside this directory.</li>
+<li>Add an XML node for one of the built-in transitions.</li>
+</ol>
+
+<p>For example, the following resource file specifies the {@link android.transition.Fade}
+transition:</p>
+
+<p class="code-caption">res/transition/fade_transition.xml</p>
+
+<pre>
+&lt;fade xmlns:android="http://schemas.android.com/apk/res/android" />
+</pre>
+
+<p>The following code snippet shows how to inflate a {@link android.transition.Transition}
+instance inside your activity from a resource file:</p>
+
+<pre>
+Transition mFadeTransition =
+        TransitionInflater.from(this).
+        inflateTransition(R.transition.fade_transition);
+</pre>
+
+
+<h3 id="FromCode">Create a transition instance in your code</h3>
+
+<p>This technique is useful for creating transition objects dynamically if you modify the user
+interface in your code, and to create simple built-in transition instances with few or
+no parameters.</p>
+
+<p>To create an instance of a built-in transition, invoke one of the public constructors in
+the subclasses of the {@link android.transition.Transition} class. For example, the following
+code snippet creates an instance of the {@link android.transition.Fade} transition:</p>
+
+<pre>
+Transition mFadeTransition = new Fade();
+</pre>
+
+
+
+<h2 id="Apply">Apply a Transition</h2>
+
+<p>You typically apply a transition to change between different view hierarchies in response
+to an event, such as a user action. For example, consider a search app: when the user enters
+a search term and clicks the search button, the app changes to the scene that represents the
+results layout while applying a transition that fades out the search button and fades in the
+search results.</p>
+
+<p>To make a scene change while applying a transition in response to some event in your
+activity, call the {@link android.transition.TransitionManager#go TransitionManager.go()}
+static method with the ending scene and the transition instance to use for the animation,
+as shown in the following snippet:</p>
+
+<pre>
+TransitionManager.go(mEndingScene, mFadeTransition);
+</pre>
+
+<p>The framework changes the view hierarchy inside the scene root with the view hierarchy
+from the ending scene while running the animation specified by the transition instance. The
+starting scene is the ending scene from the last transition. If there was no previous
+transition, the starting scene is determined automatically from the current state of the
+user interface.</p>
+
+<p>If you do not specify a transition instance, the transition manager can apply an automatic
+transition that does something reasonable for most situations. For more information, see the
+API reference for the {@link android.transition.TransitionManager} class.</p>
+
+
+
+<h2 id="Targets">Choose Specific Target Views</h2>
+
+<p>The framework applies transitions to all views in the starting and ending scenes by
+default. In some cases, you may only want  to apply an animation to a subset of views in a
+scene. For example, the framework does not support animating changes to
+{@link android.widget.ListView} objects, so you should not try to animate them during a
+transition. The framework enables you to select specific views you want to animate.</p>
+
+<p>Each view that the transition animates is called a <em>target</em>. You can only
+select targets that are part of the view hierarchy associated with a scene.</p>
+
+<p>To remove one or more views from the list of targets, call the {@link
+android.transition.Transition#removeTarget removeTarget()} method before starting
+the transition. To add only the views you specify to the list of targets, call the
+{@link android.transition.Transition#addTarget addTarget()} method. For more
+information, see the API reference for the {@link android.transition.Transition} class.</p>
+
+
+
+<h2 id="Multiple">Specify Multiple Transitions</h2>
+
+<p>To get the most impact from an animation, you should match it to the type of changes
+that occur between the scenes. For example, if you are removing some views and adding others
+between scenes, a fade out/fade in animation provides a noticeable indication that some views
+are no longer available. If you are moving views to different points on the screen, a better
+choice would be to animate the movement so that users notice the new location of the views.</p>
+
+<p>You do not have to choose only one animation, since the transitions framework enables you
+to combine animation effects in a transition set that contains a group of individual built-in
+or custom transitions.</p>
+
+<p>To define a transition set from a collection of transitions in XML, create a resource file
+in the <code>res/transitions/</code> directory and list the transitions under the
+<code>transitionSet</code> element. For example, the following snippet shows how to specify a
+transition set that has the same behaviour as the {@link android.transition.AutoTransition}
+class:</p>
+
+<pre>
+&lt;transitionSet xmlns:android="http://schemas.android.com/apk/res/android"
+    android:transitionOrdering="sequential">
+    &lt;fade android:fadingMode="fade_out" />
+    &lt;changeBounds />
+    &lt;fade android:fadingMode="fade_in" />
+&lt;/transitionSet>
+</pre>
+
+<p>To inflate the transition set into a {@link android.transition.TransitionSet} object in
+your code, call the {@link android.transition.TransitionInflater#from TransitionInflater.from()}
+method in your activity. The {@link android.transition.TransitionSet} class extends from the
+{@link android.transition.Transition} class, so you can use it with a transition manager just
+like any other {@link android.transition.Transition} instance.</p>
+
+
+
+<h2 id="NoScenes">Apply a Transition Without Scenes</h2>
+
+<p>Changing view hierarchies is not the only way to modify your user interface. You can also
+make changes by adding, modifying, and removing child views within the current hierarchy. For
+example, you can implement a search interaction with just a single layout. Start with the
+layout showing a search entry field and a search icon. To change the user interface to show
+the results, remove the search button when the user clicks it by calling the {@link
+android.view.ViewGroup#removeView ViewGroup.removeView()} method, and add the search results by
+calling {@link android.view.ViewGroup#addView ViewGroup.addView()} method.</p>
+
+<p>You may want to use this approach if the alternative is to have two hierarchies that are
+nearly identical. Rather than having to create and maintain two separate layout files for a
+minor difference in the user interface, you can have one layout file containing a view
+hierarchy that you modify in code.</p>
+
+<p>If you make changes within the current view hierarchy in this fashion, you do not need to
+create a scene. Instead, you can create and apply a transition between two states of a view
+hierarchy using a <em>delayed transition</em>. This feature of the transitions framework
+starts with the current view hierarchy state, records changes you make to its views, and applies
+a transition that animates the changes when the system redraws the user interface.</p>
+
+<p>To create a delayed transition within a single view hierarchy, follow these steps:</p>
+
+<ol>
+<li>When the event that triggers the transition occurs, call the {@link
+android.transition.TransitionManager#beginDelayedTransition
+TransitionManager.beginDelayedTransition()} method providing the parent view of all the views
+you want to change and the transition to use. The framework stores the current state of the
+child views and their property values.</li>
+<li>Make changes to the child views as required by your use case. The framework records
+the changes you make to the child views and their properties.</li>
+<li>When the system redraws the user interface according to your changes, the framework
+animates the changes between the original state and the new state.</li>
+</ol>
+
+<p>The following example shows how to animate the addition of a text view to a view hierarchy
+using a delayed transition. The first snippet shows the layout definition file:</p>
+
+<p class="code-caption">res/layout/activity_main.xml</p>
+
+<pre>
+&lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
+    android:id="@+id/mainLayout"
+    android:layout_width="match_parent"
+    android:layout_height="match_parent" >
+    &lt;EditText
+        android:id="@+id/inputText"
+        android:layout_alignParentLeft="true"
+        android:layout_alignParentTop="true"
+        android:layout_width="match_parent"
+        android:layout_height="wrap_content" />
+    ...
+&lt;/RelativeLayout>
+</pre>
+
+<p>The next snippet shows the code that animates the addition of the text view:</p>
+
+<p class="code-caption">MainActivity.java</p>
+
+<pre>
+private TextView mLabelText;
+private Fade mFade;
+private ViewGroup mRootView;
+...
+
+// Load the layout
+this.setContentView(R.layout.activity_main);
+...
+
+// Create a new TextView and set some View properties
+mLabelText = new TextView();
+mLabelText.setText("Label").setId("1");
+
+// Get the root view and create a transition
+mRootView = (ViewGroup) findViewById(R.id.mainLayout);
+mFade = new Fade(IN);
+
+// Start recording changes to the view hierarchy
+TransitionManager.beginDelayedTransition(mRootView, mFade);
+
+// Add the new TextView to the view hierarchy
+mRootView.addView(mLabelText);
+
+// When the system redraws the screen to show this update,
+// the framework will animate the addition as a fade in
+</pre>
+
+
+
+<h2 id="Callbacks">Define Transition Lifecycle Callbacks</h2>
+
+<p>The transition lifecycle is similar to the activity lifecycle. It represents the transition
+states that the framework monitors during the time between a call to the {@link
+android.transition.TransitionManager#go TransitionManager.go()} method and the completion of
+the animation. At important lifecycle states, the framework invokes callbacks defined by
+the {@link android.transition.Transition.TransitionListener TransitionListener}
+interface.</p>
+
+<p>Transition lifecycle callbacks are useful, for example, for copying a view property value
+from the starting view hierarchy to the ending view hierarchy during a scene change. You
+cannot simply copy the value from its starting view to the view in the ending view hierarchy,
+because the ending view hierarchy is not inflated until the transition is completed.
+Instead, you need to store the value in a variable and then copy it into the ending view
+hierarchy when the framework has finished the transition. To get notified when the transition
+is completed, you can implement the {@link
+android.transition.Transition.TransitionListener#onTransitionEnd
+TransitionListener.onTransitionEnd()} method in your activity.</p>
+
+<p>For more information, see the API reference for the {@link
+android.transition.Transition.TransitionListener TransitionListener} class.</p>

+
+<h2 id="presenter">Create a Card Presenter</h2>
+
+<p>A {@link android.support.v17.leanback.widget.Presenter} generates views and binds objects to them
+on demand. In the browse fragment where your app presents its content to the user, you create a
+{@link android.support.v17.leanback.widget.Presenter} for the content cards and pass it to the adapter
+that adds the content to the screen. In the following code, the <code>CardPresenter</code> is created
+in the {@link android.support.v4.app.LoaderManager.LoaderCallbacks#onLoadFinished(android.support.v4.content.Loader, java.lang.Object) onLoadFinished()}
+callback of the {@link android.support.v4.app.LoaderManager}.</p>
+
+<pre>
+&#64;Override
+public void onLoadFinished(Loader&lt;HashMap&lt;String, List&lt;Movie&gt;&gt;&gt; arg0,
+                           HashMap&lt;String, List&lt;Movie&gt;&gt; data) {
+
+    mRowsAdapter = new ArrayObjectAdapter(new ListRowPresenter());
+    CardPresenter cardPresenter = new CardPresenter();
+
+    int i = 0;
+
+    for (Map.Entry&lt;String, List&lt;Movie&gt;&gt; entry : data.entrySet()) {
+        ArrayObjectAdapter listRowAdapter = new ArrayObjectAdapter(cardPresenter);
+        List&lt;Movie&gt; list = entry.getValue();
+
+        for (int j = 0; j &lt; list.size(); j++) {
+            listRowAdapter.add(list.get(j));
+        }
+        HeaderItem header = new HeaderItem(i, entry.getKey(), null);
+        i++;
+        mRowsAdapter.add(new ListRow(header, listRowAdapter));
+    }
+
+    HeaderItem gridHeader = new HeaderItem(i, getString(R.string.more_samples),
+            null);
+
+    GridItemPresenter gridPresenter = new GridItemPresenter();
+    ArrayObjectAdapter gridRowAdapter = new ArrayObjectAdapter(gridPresenter);
+    gridRowAdapter.add(getString(R.string.grid_view));
+    gridRowAdapter.add(getString(R.string.error_fragment));
+    gridRowAdapter.add(getString(R.string.personal_settings));
+    mRowsAdapter.add(new ListRow(gridHeader, gridRowAdapter));
+
+    setAdapter(mRowsAdapter);
+
+    updateRecommendations();
+}
+</pre>
+
+<h2 id="card-view">Create a Card View</h2>
+
+<p>In this step, you build the card presenter with a view holder for the card view that describes
+your media content items. Note that each presenter must only create one view type. If you have two
+different card view types then you need two different card presenters.</p>
+
+<p>In the {@link android.support.v17.leanback.widget.Presenter}, implement an
+{@link android.support.v17.leanback.widget.Presenter#onCreateViewHolder(android.view.ViewGroup) onCreateViewHolder()}
+callback that creates a view holder that can be used to display a content item.</p>
+
+<pre>
+&#64;Override
+public class CardPresenter extends Presenter {
+
+    private Context mContext;
+    private static int CARD_WIDTH = 313;
+    private static int CARD_HEIGHT = 176;
+    private Drawable mDefaultCardImage;
+
+    &#64;Override
+    public ViewHolder onCreateViewHolder(ViewGroup parent) {
+        mContext = parent.getContext();
+        mDefaultCardImage = mContext.getResources().getDrawable(R.drawable.movie);
+...
+</pre>
+
+<p>In the {@link android.support.v17.leanback.widget.Presenter#onCreateViewHolder(android.view.ViewGroup)
+onCreateViewHolder()} method, create a card view for content items. The sample below uses an
+{@link android.support.v17.leanback.widget.ImageCardView}.</p>
+
+<p>When a card is selected, the default behavior expands it to a larger size. If you want to designate
+a different color for the selected card, call {@link android.support.v17.leanback.widget.BaseCardView#setSelected(boolean)
+setSelected()}
+as shown here.</p>
+
+<pre>
+...
+    ImageCardView cardView = new ImageCardView(mContext) {
+        &#64;Override
+        public void setSelected(boolean selected) {
+            int selected_background = mContext.getResources().getColor(R.color.detail_background);
+            int default_background = mContext.getResources().getColor(R.color.default_background);
+            int color = selected ? selected_background : default_background;
+            findViewById(R.id.info_field).setBackgroundColor(color);
+            super.setSelected(selected);
+        }
+    };
+...
+</pre>
+
+<p>When the user opens your app, the {@link android.support.v17.leanback.widget.Presenter.ViewHolder}
+displays the <code>CardView</code> objects for your content items. You need to set these to receive
+focus from the D-pad controller by calling {@link android.view.View#setFocusable(boolean) setFocusable(true)}
+and {@link android.view.View#setFocusableInTouchMode(boolean) setFocusableInTouchMode(true)}.</p>
+
+<pre>
+...
+    cardView.setFocusable(true);
+    cardView.setFocusableInTouchMode(true);
+    return new ViewHolder(cardView);
+}
+</pre>
+
+<p>When the user selects the {@link android.support.v17.leanback.widget.ImageCardView}, it expands
+to reveal its text area with the background color you specify, as shown in figure 2.</p>
+
+<img itemprop="image" src="{@docRoot}images/tv/card-view.png" alt="App card view"/>
