isOverScrolled
Deprecated
Use isOverScrolled directly.
Returns whether the current Scroller is currently returning to a valid position. Valid bounds were provided by the fling method. One should check this value before calling startScroll as the interpolation currently in progress to restore a valid position will then be stopped. The caller has to take into account the fact that the started scroll will start from an overscrolled position.
Return
true when the current position is overscrolled and in the process of interpolating back to a valid value.
