SimpleOnScaleListener

interface SimpleOnScaleListener : ScaleGestureDetector.OnScaleListener

A convenience class to extend when you only want to listen for a subset of scale-related events.

This implements all methods in OnScaleListener but does nothing. OnRotateListener.onRotate returns false so that a subclass can retrieve the accumulated rotation factor in an overridden OnRotateListener.onRotateEnd. OnRotateListener.onRotateBegin returns true.
