推荐答案

您必须声明此使用，权限AndroidManifest：

you have to declare this uses-permission on AndroidManifest:

<uses-permission android:name="android.permission.WAKE_LOCK" />

而在你的code活动：

And in your code Activity:

PowerManager powerManager = (PowerManager)context.getSystemService(Context.POWER_SERVICE);
WakeLock wakeLock = powerManager.newWakeLock(PowerManager.FULL_WAKE_LOCK, "My Lock");
wakeLock.acquire();

不过，别忘了释放此锁，当你的应用程序被暂停或摧毁这样做：

Just remember to release this lock when your application is paused or destroyed by doing this:

wakeLock.release();

通常情况下，它的建议致电获得方式的 onResume（）您的活动，并在发布法里面的的onPause （）。这样，我们保证我们的应用程序仍处于被暂停的情况下表现良好或恢复。

Usually, it's suggested to call the acquire method inside the onResume() of your activity and the release method in onPause(). This way we guarantee that our application still performs well in the case of being paused or resumed.
