GestureDetectorCompat

public final class GestureDetectorCompat
extends Object

java.lang.Object
↳	android.support.v4.view.GestureDetectorCompat

Detects various gestures and events using the supplied MotionEvents. The GestureDetector.OnGestureListener callback will notify users when a particular motion event has occurred. This class should only be used with MotionEvents reported via touch (don't use for trackball events).

This compatibility implementation of the framework's GestureDetector guarantees the newer focal point scrolling behavior from Jellybean MR1 on all platform versions.

To use this class:

Create an instance of the GestureDetectorCompat for your View
In the onTouchEvent(MotionEvent) method ensure you call onTouchEvent(MotionEvent). The methods defined in your callback will be executed when the events occur.
