推荐答案

添加安卓keepScreenOn =真正的来为这次活动你的布局XML资源的一些小部件。只要该部件是在屏幕上可见，屏幕也不会自动关闭。

Add android:keepScreenOn="true" to some widget in your layout XML resource for this activity. So long as that widget is visible on the screen, the screen will not turn off automatically.

A WakeLock 建议的那样，其他的答案，在技术上将工作。但你必须手动释放 WakeLock （如果你陷入困境，高达，屏幕上会停留在很长一段时间）。而且，由于你的可以的搞砸了，你需要的 WAKE_LOCK 许可。使用 keepScreenOn 避免这一切。

A WakeLock, as suggested by other answers, technically will work. But then you have to manually release the WakeLock (if you mess that up, the screen will stay on a long time). And, since you could mess it up, you need the WAKE_LOCK permission. Using keepScreenOn avoids all of that.
