/**
 * {@link android.view.FocusFinder#findNextFocus(android.view.ViewGroup, android.view.View, int)}
 * and
 * {@link android.view.View#requestFocus(int, android.graphics.Rect)}
 * work together to give a newly focused item a hint about the most interesting
 * rectangle of the previously focused view.  The view taking focus can use this
 * to set an internal selection more appropriate using this rect.
 *
 * This Activity excercises that behavior using three adjacent {@link com.android.frameworktest.util.InternalSelectionView}
 * that report interesting rects when giving up focus, and use interesting rects
 * when taking focus to best select the internal row to show as selected.
