AndroidManifest.xml加两个权限


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

Android屏幕解锁:

WakeLock mWakelock = pm.newWakeLock(PowerManager.ACQUIRE_CAUSES_WAKEUP |PowerManager.SCREEN_DIM_WAKE_LOCK, "SimpleTimer"); 
mWakelock.acquire(); 
//... 
mWakelock.release();//关闭
