如何檢查android wifi連接？

Question

我想檢查它是否連接到WiFi。如果連接，手機保持沉默。當程序運行的應用程序停止工作

ConnectivityManager connManager = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE); 
      NetworkInfo mWifi = connManager.getNetworkInfo(ConnectivityManager.TYPE_WIFI); 

      if (mWifi.isConnected()) { 
       final AudioManager audioManager= 
         (AudioManager)getSystemService(getApplicationContext().AUDIO_SERVICE); 
       audioManager.setRingerMode(AudioManager.RINGER_MODE_SILENT); 

      } 
      else 
      { 
       final AudioManager audioManager= 
         (AudioManager)getSystemService(getApplicationContext().AUDIO_SERVICE); 
       audioManager.setRingerMode(AudioManager.RINGER_MODE_NORMAL); 
      }

您可以直接使用此方法，如果連那麼它將返回true，否則返回false記住它不會在模擬器上工作，請測試它真實的設備..謝謝

private boolean isNetworkAvailable() { 
     ConnectivityManager connectivityManager = (ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE); 
     NetworkInfo netInfo = connectivityManager.getActiveNetworkInfo(); 
     if(netInfo != null && netInfo.isConnected()) { 
      //we are connected to a network 
      return true; 
     } 
     else 
      return false; 
    }
