FocusChangeWithInterestingRectHintTestpublic class FocusChangeWithInterestingRectHintTest extends android.test.ActivityInstrumentationTestCase | {@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 tests that behavior using three adjacent {@link android.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. |
