推荐答案

你使用启动发 thread.start（）在 surfaceCreated 回调？如果是这样，就会有如果你没有使用一个包含检查，如果你的游戏已经开始了一个成员变量始终是一个错误。

Do you start your Thread by using thread.start() in the surfaceCreated callback? If so, there will always be an error if you're not using a member variable that contains a check if your game has been started.

您需要暂停的发在 surfaceDestroyed 回调使用等待（ ）命令，所以它不会暂停时重申你的游戏code。你开始你的应用程序（第一次或者第二次），你需要启动（），或通知（）这（暂停后），视情况而定。

You need to "pause" your Thread in the surfaceDestroyed callback using wait() command so it doesn't reiterate your game code during pause. Next time you're starting your application (for the first time or maybe second time) you need to start() it or notify() it (after pausing) depending on the circumstances.

最后，永远永远张贴code。这将吸引人们正确，正确回答这个问题。

At last, always always post code. That will engage people to answer the question properly and correct.
