如何使用单个GestureDetector实例检测多个手势？

import android.support.v4.view.GestureDetectorCompat;
import android.view.GestureDetector;
import android.view.MotionEvent;
import android.view.View;

public class MyView extends View {
    private GestureDetectorCompat mGestureDetector;

    public MyView(Context context) {
        super(context);
        mGestureDetector = new GestureDetectorCompat(context, new MyGestureListener());
    }

    @Override
    public boolean onTouchEvent(MotionEvent event) {
        mGestureDetector.onTouchEvent(event);
        return true;
    }

    private class MyGestureListener extends GestureDetector.SimpleOnGestureListener {
        @Override
        public boolean onDown(MotionEvent event) {
            // 处理按下事件
            return true;
        }

        @Override
        public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX, float distanceY) {
            // 处理滑动事件
            return true;
        }

        @Override
        public boolean onDoubleTap(MotionEvent event) {
            // 处理双击事件
            return true;
        }
    }
}
