Android 判斷屏幕開關狀態方式總結

Android判斷屏幕開關狀態

 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

    }


  }
  }

//注冊廣播
ScreenReceiver sOnBroadcastReciver=new ScreenReceiver();
    IntentFilter recevierFilter=new IntentFilter();
    recevierFilter.addAction(Intent.ACTION_SCREEN_ON);
    recevierFilter.addAction(Intent.ACTION_SCREEN_OFF);
    registerReceiver(sOnBroadcastReciver, recevierFilter);


//取消注冊
if(sOnBroadcastReciver!=null)
    {
      unregisterReceiver(sOnBroadcastReciver);
    }

注意：亮屏和熄屏廣播只能通過動態注冊才能收到。
