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
