android触摸手势OnGestureListener

OnGestureListener 可以处理一些简单的触摸手势&＃xff0c;比如滑动&＃xff0c;长按等&＃xff0c;

OnGestureListener不能直接设置侦听的&＃xff0c;可以设置OnTouchListener&＃xff0c;让其指向OnGestureListener

public class GestureView extends View implements OnTouchListener, OnGestureListener
{GestureDetector mGestureDetector;public GestureView(Context context){super(context);this.setOnTouchListener(this);mGestureDetector &＃61; new GestureDetector(this);}&＃64;Overridepublic boolean onDown(MotionEvent e){Log.i("&＃64;fred", "触摸手势&＃xff1a;onDown");return true;}&＃64;Overridepublic boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY){if (e2.getX() - e1.getX() > 50){Log.i("&＃64;fred", "触摸手势&＃xff1a;onFling");}return true;}&＃64;Overridepublic void onLongPress(MotionEvent e){Log.i("&＃64;fred", "触摸手势&＃xff1a;onLongPress");}&＃64;Overridepublic boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX, float distanceY){Log.i("&＃64;fred", "触摸手势&＃xff1a;onScroll");return true;}&＃64;Overridepublic void onShowPress(MotionEvent e){Log.i("&＃64;fred", "触摸手势&＃xff1a;onShowPress");}&＃64;Overridepublic boolean onSingleTapUp(MotionEvent e){Log.i("&＃64;fred", "触摸手势&＃xff1a;onSingleTapUp");return true;}&＃64;Overridepublic boolean onTouch(View v, MotionEvent event){// 将MotionEvent事件传到GestureDetectorreturn mGestureDetector.onTouchEvent(event);}}

比如点击一下屏幕&＃xff1a;
