+ * <p>To add a progress bar to a layout file, you can use the {@code &lt;ProgressBar&gt;} element.
+ * By default, the progress bar is a spinning wheel (an indeterminate indicator). To change to a
+ * horizontal progress bar, apply the {@link android.R.style#Widget_ProgressBar_Horizontal
+ * Widget.ProgressBar.Horizontal} style, like so:</p>
+ *
+ * <pre>
+ * &lt;ProgressBar
+ *     style="@android:style/Widget.ProgressBar.Horizontal"
+ *     ... /&gt;</pre>
+ *
+ * <p>If you will use the progress bar to show real progress, you must use the horizontal bar. You
+ * can then increment the  progress with {@link #incrementProgressBy incrementProgressBy()} or
+ * {@link #setProgress setProgress()}. By default, the progress bar is full when it reaches 100. If
+ * necessary, you can adjust the maximum value (the value for a full bar) using the {@link
+ * android.R.styleable#ProgressBar_max android:max} attribute. Other attributes available are listed
+ * below.</p>
+ *
+ * <p>Another common style to apply to the progress bar is {@link
+ * android.R.style#Widget_ProgressBar_Small Widget.ProgressBar.Small}, which shows a smaller
+ * version of the spinning wheel&mdash;useful when waiting for content to load.
+ * For example, you can insert this kind of progress bar into your default layout for
+ * a view that will be populated by some content fetched from the Internet&mdash;the spinning wheel
+ * appears immediately and when your application receives the content, it replaces the progress bar
+ * with the loaded content. For example:</p>
+ *
+ * <pre>
+ * &lt;LinearLayout
+ *     android:orientation="horizontal"
+ *     ... &gt;
+ *     &lt;ProgressBar
+ *         android:layout_width="wrap_content"

+ *         android:layout_height="wrap_content"
+ *         android:text="@string/loading" /&gt;
+ * &lt;/LinearLayout&gt;</pre>
+ *
+ * <p>Other progress bar styles provided by the system include:</p>
+ * <ul>
+ * <li>{@link android.R.style#Widget_ProgressBar_Horizontal Widget.ProgressBar.Horizontal}</li>
+ * <li>{@link android.R.style#Widget_ProgressBar_Small Widget.ProgressBar.Small}</li>
