Android 解屏幕锁与点亮屏幕

核心提示： KeyguardManager km= (KeyguardManager) getSystemService(Context.KEYGUARD_SERVICE); //得到键盘锁管理器对象KeyguardLock kl = km.newKeyguardLock("unLock"); //参数是L

 KeyguardManager km= (KeyguardManager) getSystemService(Context.KEYGUARD_SERVICE); //得到键盘锁管理器对象
KeyguardLock kl = km.newKeyguardLock("unLock"); //参数是LogCat里用的Tag
kl.disableKeyguard(); //解锁
PowerManager pm=(PowerManager) getSystemService(Context.POWER_SERVICE);//获取电源管理器对象
PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.ACQUIRE_CAUSES_WAKEUP | PowerManager.SCREEN_DIM_WAKE_LOCK, "bright");
//获取PowerManager.WakeLock对象,后面的参数|表示同时传入两个值,最后的是LogCat里用的Tag
wl.acquire();//点亮屏幕
wl.release();//释放
要实现自动解锁和点亮屏幕的功能则需要在AndroidManifest.xml添加权限:
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="android.permission.DISABLE_KEYGUARD" />
