Android 解螢幕鎖與點亮螢幕

本文 KeyguardManager  km= (KeyguardManager) getSystemService(Context.KEYGUARD_SERVICE); //得到鍵盤鎖管理器對象KeyguardLock kl = km.newKeyguardLock("unLock"); //參數是LogCat裡用的Tagkl.disableKeyguard(); //解鎖PowerManager pm=(PowerManager) getSystemService(Context.POWER_SERVICE);//擷取電源管理器對象PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.ACQUIRE_CAUSES_WAKEUP | PowerManager.SCREEN_DIM_WAKE_LOCK, "bright");//擷取PowerManager.WakeLock對象,後面的參數|表示同時傳入兩個值,最後的是LogCat裡用的Tagwl.acquire();//點亮螢幕wl.release();//釋放要實現自動解鎖和點亮螢幕的功能則需要在AndroidManifest.xml添加許可權:<uses-permission android:name="android.permission.WAKE_LOCK" /> <uses-permission android:name="android.permission.DISABLE_KEYGUARD" />
