原标题:Method OnSensorChanged() when screen is lock

On my Samsung Galaxy S 2 I have the known bug when OnSensorChanged() method does not call when screen is lock (http://code.google.com/p/android/issues/detail?id=3708 ). Is there any solution for this?

问题回答

You solve the problem by getting a partial wake lock from the power manager which keeps the CPU from sleeping when the screen goes off.

PowerManager pm = (PowerManager) getSystemService(POWER_SERVICE);
PowerManager.WakeLock lock = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "SensorRead");
lock.acquire();

保证在你这样做时释放他们,否则你不会耗尽电池。

您也希望得到这一许可。
