关于手势识别

public class Gesture implements OnGestureListener {
    private GestureDetector gestureDetector;
    public void onTouchEvent(MotionEvent event) {
        gestureDetector.onTouchEvent(event);
    }
    public Gesture(Context context) {
        gestureDetector = new GestureDetector(context, this);
    }
    @Override
    public boolean onDown(MotionEvent e) {
        // TODO Auto-generated method stub
        return false;
    }
    @Override
    public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX,
            float velocityY) {
        // TODO Auto-generated method stub
                                                                                                              
        return false;
    }
    @Override
    public void onLongPress(MotionEvent e) {
        // TODO Auto-generated method stub
    }
    @Override
    public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX,
            float distanceY) {
        // TODO Auto-generated method stub
        return false;
    }
    @Override
    public void onShowPress(MotionEvent e) {
        // TODO Auto-generated method stub
    }
    @Override
    public boolean onSingleTapUp(MotionEvent e) {
        // TODO Auto-generated method stub
        return false;
    }
}

gesture = new Gesture(context);//在适当时刻初始化Gesture

gesture.onTouchEvent(event);//放在onTouchEvent中，即将event传递到gesture让其进行识别
