Methods Summary
public voidgetDrawingRect(android.graphics.Rect outRect)
This method returns the drawing rect for the view which is different from the regular drawing rect, since we layout all children in the {@link NotificationStackScrollLayout} at position 0 and usually the translation is neglected. The standard implementation doesn't account for translation.

param
outRect The (scrolled) drawing bounds of the view.

        super.getDrawingRect(outRect);
        float translationX = ((ViewGroup) mParent).getTranslationX();
        float translationY = ((ViewGroup) mParent).getTranslationY();
        outRect.left += translationX;
        outRect.right += translationX;
        outRect.top += translationY;
        outRect.bottom += translationY;
public booleanhasOverlappingRendering()

        return false;

return
Whether the button is currently static and not being animated.
