| Methods Summary |
|---|
| public void | fyiWillBeAdvancedByHostKThx()Called by an {@link android.appwidget.AppWidgetHost} to indicate that it will be
automatically advancing the views of this {@link AdapterViewFlipper} by calling
{@link AdapterViewFlipper#advance()} at some point in the future. This allows
{@link AdapterViewFlipper} to prepare by no longer Advancing its children.
mAdvancedByHost = true;
updateRunning(false);
|
| public int | getFlipInterval()Returns the flip interval, in milliseconds.
return mFlipInterval;
|
| public boolean | isAutoStart()Returns true if this view automatically calls {@link #startFlipping()}
when it becomes attached to a window.
return mAutoStart;
|
| public boolean | isFlipping()Returns true if the child views are flipping.
return mStarted;
|
| protected void | onAttachedToWindow()
super.onAttachedToWindow();
// Listen for broadcasts related to user-presence
final IntentFilter filter = new IntentFilter();

// OK, this is gross but needed. This class is supported by the
// remote views machanism and as a part of that the remote views
// can be inflated by a context for another user without the app
// having interact users permission - just for loading resources.
// For exmaple, when adding widgets from a user profile to the
// home screen. Therefore, we register the receiver as the current
// user not the one the context is for.
