Android 手勢監聽之雙擊監聽

超級簡單的自定義view

package yesun.app7;

import android.content.Context;
import android.util.AttributeSet;
import android.view.GestureDetector;
import android.view.MotionEvent;
import android.view.View;

/**

public class MyView extends View {
    private GestureDetector gestureDetector;
    private boolean background = false;

    public MyView(Context context) {
        this(context, null);
    }

    public MyView(Context context, AttributeSet attrs) {
        super(context, attrs);
        gestureDetector = new GestureDetector(context, new GestureDetector.SimpleOnGestureListener() {

            @Override
            public boolean onDoubleTap(MotionEvent e) {
                if (background)
                    setBackgroundColor(0xffff00ff);
                else setBackgroundColor(0xFF001AFF);
                background = !background;
                return super.onDoubleTap(e);
            }
        });
    }


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