即使 isClickable 属性 设置为 false，我也可以点击按钮
I can click buttons even when the isClickable property set to false
Activity代码
在这里，enableOrDisable()，我正在调用 if myValue = 2，并且我已经按照之前的意图发送了 2 值 activity 但是，我仍然可以点击按钮，请发送一些解决方案该怎么做或我在做什么错？帮助将不胜感激。我正在尝试这样做，如果 myValue 不是 2 那么我的按钮都可以点击但是一旦 myValue 1 的玩家点击它就会在 firebase 中注册并被两个玩家收听并且在听完点击更改的玩家之后所有剩余的未点击按钮都为 false 和听的玩家，那个播放器按钮变为可点击但我不知道为什么两个玩家可以同时点击。

您也许应该使用“setEnabled”而不是 isClickable？
使用setEnabled属性
代码像
button1.setEnabled = false
button1.isClickable = false
问题是我是在 setContentView() 上面做的
