【问题描述】：
我正在开发具有 15 个按钮的应用程序。每个按钮都有不同的声音。我希望在按下按钮时播放声音，当抬起手指停止声音并且效果很好时，LogCat 中不会显示延迟和错误/警告。
但后来我在屏幕规格较差的设备（没有多点触控的设备）上测试了我的应用，我注意到一次只能按下 1 个按钮，直到手指抬起为止。
所以我需要这样的东西：
当手指在按钮 1 的边界内时，按钮 1 将被按下。当手指移动并离开 button1 边框时，按钮 1 将不再被按下，当手指进入按钮 2 或按钮 4 边框或任何其他按钮时，该按钮将被按下。所以我需要激活手指所在的按钮。 但是使用我的代码，即使在手指离开按钮 1 的边界后，按钮 1 仍然被按下。 这里有图片：
这是我的 XML 布局：
