onClick监听器没有响应

标签： android onclicklistener android-handler

我正在为我的班级制作一个项目。这就像鼹鼠游戏。我有9个imageView。当你点击它们时，它们会变成一个空洞的预定义图像，如果没有，处理程序会将它改回正常，你将失去生命。但是对于一张照片，如果它出现并且你点击它，你就会失去生命。现在我已将图像修复为后者。如果我非常快地点击它们，显示生命的textView，永远不会更新到游戏结束，任务继续，但如果我慢慢点击，它会更新到游戏结束。我试过调试，发现当我很快点击它们时，代码永远不会转到onClick监听器。

以下是代码：

任何图片都可以使用，只要它名为mole4.png，当没有mmole时就可以使用hole.png

非常感谢。我将非常感谢您的帮助
