+/**
+ * <p>
+ * Visual indicator of progress in some operation. Displays a bar to the user
+ * representing how far the operation has progressed; the application can
+ * change the amount of progress (modifying the length of the bar) as it moves
+ * forward. There is also a secondary progress displayable on a progress bar
+ * which is useful for displaying intermediate progress, such as the buffer
+ * level during a streaming playback progress bar.
+ * </p>
+ *
+ * <p>
+ * A progress bar can also be made indeterminate. In indeterminate mode, the
+ * progress bar shows a cyclic animation without an indication of progress. This mode is used by
+ * applications when the length of the task is unknown. The indeterminate progress bar can be either
+ * a spinning wheel or a horizontal bar.
+ * </p>
+ *
+ * <p>The following code example shows how a progress bar can be used from
+ * a worker thread to update the user interface to notify the user of progress:
+ * </p>
+ *
+ * <pre>
+ * public class MyActivity extends Activity {
+ * private static final int PROGRESS = 0x1;
+ *
+ * private ProgressBar mProgress;
+ * private int mProgressStatus = 0;
+ *
+ * private Handler mHandler = new Handler();
+ *
+ * protected void onCreate(Bundle icicle) {
+ * super.onCreate(icicle);
+ *
+ * setContentView(R.layout.progressbar_activity);
+ *
+ * mProgress = (ProgressBar) findViewById(R.id.progress_bar);
+ *
+ * // Start lengthy operation in a background thread
+ * new Thread(new Runnable() {
+ * public void run() {
+ * while (mProgressStatus < 100) {
+ * mProgressStatus = doWork();
+ *
+ * // Update the progress bar
+ * mHandler.post(new Runnable() {
+ * public void run() {
+ * mProgress.setProgress(mProgressStatus);
+ * }
+ * });
+ * }
+ * }
+ * }).start();
+ * }
+ * }</pre>
+ *
+ * <p>To add a progress bar to a layout file, you can use the {@code <ProgressBar>} 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>
+ * <ProgressBar
+ * style="@android:style/Widget.ProgressBar.Horizontal"
+ * ... /></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—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—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>
+ * <LinearLayout
+ * android:orientation="horizontal"
+ * ... >
+ * <ProgressBar
+ * android:layout_width="wrap_content"
+ * android:layout_height="wrap_content"
+ * style="@android:style/Widget.ProgressBar.Small"
+ * android:layout_marginRight="5dp" />
+ * <TextView
+ * android:layout_width="wrap_content"
+ * android:layout_height="wrap_content"
+ * android:text="@string/loading" />
+ * </LinearLayout></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>
+ * <li>{@link android.R.style#Widget_ProgressBar_Large Widget.ProgressBar.Large}</li>
+ * <li>{@link android.R.style#Widget_ProgressBar_Inverse Widget.ProgressBar.Inverse}</li>
+ * <li>{@link android.R.style#Widget_ProgressBar_Small_Inverse
+ * Widget.ProgressBar.Small.Inverse}</li>
+ * <li>{@link android.R.style#Widget_ProgressBar_Large_Inverse
+ * Widget.ProgressBar.Large.Inverse}</li>
+ * </ul>
+ * <p>The "inverse" styles provide an inverse color scheme for the spinner, which may be necessary
+ * if your application uses a light colored theme (a white background).</p>
