Class MapGestureDetector

java.lang.Object
  com.esri.android.map.MapGestureDetector

public class MapGestureDetector
extends Object

The MapGestureDetector class is used to detects various gestures and events using the supplied MotionEvents. The MapGestureDetector.OnGestureListener callback will notify users when a particular motion event has occurred on the MapView. This class should only be used with MotionEvents reported via touch (don't use for trackball) events. To use this class:

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