| 53 | * A standard toolbar for use within application content. |
| 54 | * |
| 55 | * <p>A Toolbar is a generalization of {@link android.app.ActionBar action bars} for use |
| 56 | * within application layouts. While an action bar is traditionally part of an |
| 57 | * {@link android.app.Activity Activity's} opaque window decor controlled by the framework, |
| 58 | * a Toolbar may be placed at any arbitrary level of nesting within a view hierarchy. |
| 59 | * An application may choose to designate a Toolbar as the action bar for an Activity |
| 60 | * using the {@link android.app.Activity#setActionBar(Toolbar) setActionBar()} method.</p> |
| 61 | * |
| 62 | * <p>Toolbar supports a more focused feature set than ActionBar. From start to end, a toolbar |
| 63 | * may contain a combination of the following optional elements: |
| 64 | * |
| 65 | * <ul> |
| 66 | * <li><em>A navigation button.</em> This may be an Up arrow, navigation menu toggle, close, |
| 67 | * collapse, done or another glyph of the app's choosing. This button should always be used |
| 68 | * to access other navigational destinations within the container of the Toolbar and |
| 69 | * its signified content or otherwise leave the current context signified by the Toolbar.</li> |
| 70 | * <li><em>A branded logo image.</em> This may extend to the height of the bar and can be |
| 71 | * arbitrarily wide.</li> |
| 72 | * <li><em>A title and subtitle.</em> The title should be a signpost for the Toolbar's current |
| 73 | * position in the navigation hierarchy and the content contained there. The subtitle, |
| 74 | * if present should indicate any extended information about the current content. |
| 75 | * If an app uses a logo image it should strongly consider omitting a title and subtitle.</li> |
| 76 | * <li><em>One or more custom views.</em> The application may add arbitrary child views |
| 77 | * to the Toolbar. They will appear at this position within the layout. If a child view's |
| 78 | * {@link LayoutParams} indicates a {@link Gravity} value of |
| 79 | * {@link Gravity#CENTER_HORIZONTAL CENTER_HORIZONTAL} the view will attempt to center |
| 80 | * within the available space remaining in the Toolbar after all other elements have been |
| 81 | * measured.</li> |
| 82 | * <li><em>An {@link ActionMenuView action menu}.</em> The menu of actions will pin to the |
| 83 | * end of the Toolbar offering a few |
| 84 | * <a href="http://developer.android.com/design/patterns/actionbar.html#ActionButtons"> |
| 85 | * frequent, important or typical</a> actions along with an optional overflow menu for |
| 86 | * additional actions.</li> |
| 87 | * </ul> |
| 88 | * </p> |
| 89 | * |
| 90 | * <p>In modern Android UIs developers should lean more on a visually distinct color scheme for |
| 91 | * toolbars than on their application icon. The use of application icon plus title as a standard |
| 92 | * layout is discouraged on API 21 devices and newer.</p> |
