| ↳ | android.view.ScaleGestureDetector.SimpleOnScaleGestureListener |
A convenience class to extend when you only want to listen for a subset
of scaling-related events. This implements all methods in
ScaleGestureDetector.OnScaleGestureListener but does nothing.
onScale(ScaleGestureDetector) returns
false so that a subclass can retrieve the accumulated scale
factor in an overridden onScaleEnd.
onScaleBegin(ScaleGestureDetector) returns
true.
