Java Android游戏从后退按钮和菜单按钮崩溃

我为我缺乏android开发方面的知识提前道歉，我对此非常陌生

我用java从头开始编写了一个游戏。如果我按下菜单按钮或后退按钮，游戏将立即崩溃。我相信它会在菜单按钮上崩溃，因为我使用的是Window.FEATURE\u NO\u TITLE，我不知道为什么后退按钮会使游戏崩溃（有时它会使游戏崩溃，有时它会退出，然后当我再次打开它时，游戏会崩溃）。 如果我按下Home按钮，然后尝试返回应用程序，它也会崩溃，我猜这与surfaceCreated方法有关

基本上，我不需要这些按钮来做任何事情，所以我真正想做的就是禁用它们，这听起来很简单，但我还没有成功做到这一点

我为自己想出了一个解决方案，因为我正在使用Window.FEATURE\u NO\u TITLE。当我按下菜单按钮时，我意识到扩展ActionBarActivity会使它崩溃，所以我将其更改为仅扩展Activity。为了修复关闭和重新加载，我只是使用SurfacedStroyed方法终止了游戏

我不知道为什么选择ActionBarActivity作为默认值。

没有代码？没有堆栈跟踪？没有答案。检查：您应该在

android.app.Activity.onCreatePanelMenu（Activity.java:2579）发布崩溃的代码。
