GestureDetectorCompat

public final class GestureDetectorCompat
extends Object

java.lang.Object
   ↳ androidx.core.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.
