Android 判斷螢幕開關狀態方式總結_Android

Android判斷螢幕開關狀態

 方法一：使用系統服務

PowerManager pm= (PowerManager) mContext.getSystemService(Context.POWER_SERVICE);    if(!pm.isScreenOn())    {      //熄屏狀態    }

方法二：使用廣播

public class ScreenReceiver extends BroadcastReceiver {  @Override  public void onReceive(Context context, Intent intent) {    if (intent.getAction().equals(Intent.ACTION_SCREEN_OFF)) {      //收到亮屏廣播    } else if (intent.getAction().equals(Intent.ACTION_SCREEN_ON)) {//收到熄屏廣播    }  }  }

//註冊廣播ScreenReceiver sOnBroadcastReciver=new ScreenReceiver();    IntentFilter recevierFilter=new IntentFilter();    recevierFilter.addAction(Intent.ACTION_SCREEN_ON);    recevierFilter.addAction(Intent.ACTION_SCREEN_OFF);    registerReceiver(sOnBroadcastReciver, recevierFilter);//取消註冊if(sOnBroadcastReciver!=null)    {      unregisterReceiver(sOnBroadcastReciver);    }

注意：亮屏和熄屏廣播只能通過動態註冊才能收到。
