Android 当手指移动时，触控式监听器不会释放按钮

我有一个带有15个按钮的

RelativeLayout

，我正在做一个新项目，我希望我的应用程序可以这样做：当用户触摸例如按钮1时，Mp1将开始播放，直到用户抬起手指或将其移动到按钮2，然后按钮2上的mp2应该启动，依此类推

但这里是发生的情况，用户触摸屏幕时，升降机工作正常，但如果用户移动手指（而不是提升），如果按下按钮1，它仍将处于按下状态（向下操作），直到用户抬起手指。 大概是这样的：

我的问题:

当手指离开按钮边框以停止按钮并打开按下的按钮（手指触摸的位置）时，我需要添加什么？ 我的代码：

试试这个：

sound1.setOnTouchListener(new OnTouchListener() {
            public boolean onTouch(View v, MotionEvent event) {
                if (event.getAction() == android.view.MotionEvent.ACTION_DOWN) {
                    pressed1 = true;
                    mp1 = MediaPlayer.create(MainClass.this, R.raw.item1);
                    mp1.start();
                    sound1.setBackgroundResource(R.drawable.pad_pressed);
                    if (looping == true) {
                        mp1.setLooping(true);
                    } else if (looping == false) {
                        mp1.setLooping(false);
                    }

                } else if (event.getAction() == android.view.MotionEvent.ACTION_UP || event.getAction() == android.view.MotionEvent.ACTION_CANCEL) {
                    pressed1 = false;
                    mp1.stop();
                    mp1.reset();
                    mp1.release();
                    sound1.setBackgroundResource(R.drawable.pad_normal);
                }
                return true;
            }
        });

ACTION\u CANCEL

在父对象控制运动时发生。你可以找到更多关于

非常感谢这篇文章==>
您可以检查事件是否在视图中，或者是否未使用View.getLocationOnScreen（），它不会帮助您触发单击另一个按钮，但它至少可以停止对上一个按钮的单击。您可以在按钮所在的位置发布xml吗是的，这正在工作，但有一件事是这样的。我以前从未在派生类中使用过OnTouchEvent，我应该如何使用OnTouchEvent？我在哪里可以设置按钮ID，我尝试了所有我认为无效的方法。你需要
onTouchEvent
？在这里，此事件被禁用，因为它与RelativeLayout中的onTouch冲突。那么，我还可以如何设置使这些按钮执行某些操作？我应该用什么？我想你可以玩按钮上的标签。我已经更新了我的答案。如果你按下或点击b1，你有一首歌。通过滑动到另一个按钮，新歌曲开始。如果您移动到该区域之外，歌曲将停止。
