关于屏幕解锁的实例

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:
KeyguardManager keyguardManager = (KeyguardManager)getSystemService(KEYGUARD_SERVICE); 
        KeyguardLock keyguardLock = keyguardManager.newKeyguardLock(""); 
        keyguardLock.disableKeyguard();
Android 点亮屏幕:
PowerManager pm = (PowerManager)getSystemService(POWER_SERVICE); 
WakeLock mWakelock = pm.newWakeLock(PowerManager.ACQUIRE_CAUSES_WAKEUP |PowerManager.SCREEN_DIM_WAKE_LOCK, "SimpleTimer"); 
mWakelock.acquire(); 
//... 
mWakelock.release();//关闭
