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> + * + * <p><strong>XML attributes</b></strong> + * <p> + * See {@link android.R.styleable#ProgressBar ProgressBar Attributes}, + * {@link android.R.styleable#View View Attributes} + * </p> + * + * @attr ref android.R.styleable#ProgressBar_animationResolution + * @attr ref android.R.styleable#ProgressBar_indeterminate + * @attr ref android.R.styleable#ProgressBar_indeterminateBehavior + * @attr ref android.R.styleable#ProgressBar_indeterminateDrawable + * @attr ref android.R.styleable#ProgressBar_indeterminateDuration + * @attr ref android.R.styleable#ProgressBar_indeterminateOnly + * @attr ref android.R.styleable#ProgressBar_interpolator + * @attr ref android.R.styleable#ProgressBar_max + * @attr ref android.R.styleable#ProgressBar_maxHeight + * @attr ref android.R.styleable#ProgressBar_maxWidth + * @attr ref android.R.styleable#ProgressBar_minHeight + * @attr ref android.R.styleable#ProgressBar_minWidth + * @attr ref android.R.styleable#ProgressBar_progress + * @attr ref android.R.styleable#ProgressBar_progressDrawable + * @attr ref android.R.styleable#ProgressBar_secondaryProgress + */ +@RemoteView +public class IcsProgressBar extends View { + private static final boolean IS_HONEYCOMB = Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB;
