OnGestureListener 可以处理一些简单的触摸手势，比如滑动，长按等，

OnGestureListener不能直接设置侦听的，可以设置OnTouchListener，让其指向OnGestureListener

public class GestureView extends View implements OnTouchListener, OnGestureListener{GestureDetectormGestureDetector;public GestureView(Context context){super(context);this.setOnTouchListener(this);mGestureDetector = new GestureDetector(this);}@Overridepublic boolean onDown(MotionEvent e){Log.i("@fred", "触摸手势：onDown");return true;}@Overridepublic boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY){if (e2.getX() - e1.getX() > 50){Log.i("@fred", "触摸手势：onFling");}return true;}@Overridepublic void onLongPress(MotionEvent e){Log.i("@fred", "触摸手势：onLongPress");}@Overridepublic boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX, float distanceY){Log.i("@fred", "触摸手势：onScroll");return true;}@Overridepublic void onShowPress(MotionEvent e){Log.i("@fred", "触摸手势：onShowPress");}@Overridepublic boolean onSingleTapUp(MotionEvent e){Log.i("@fred", "触摸手势：onSingleTapUp");return true;}@Overridepublic boolean onTouch(View v, MotionEvent event){// 将MotionEvent事件传到GestureDetector return  mGestureDetector.onTouchEvent(event);}}
