如何獲取用戶位置基於移動SIM卡android在c＃中「

Question

我想獲取用戶的當前位置（經度和緯度）始終只使用基於SIM的網絡，而不是通過使用任何其他網絡（如WiFi ，移動數據，全球定位系統和其他網絡，甚至所有這些都在手機的禁用模式）。不一定準確的位置，但即使大致的位置。

有沒有可能得到它？如果任何人可以解釋幷包括代碼;我在谷歌搜索但沒有得到正確的相關答案。

您可以使用LocationManager.NETWORK_PROVIDER來獲取谷歌縱橫nd經度無需打開GPS

btnNWShowLocation.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View arg0) { 

      Location nwLocation = appLocationService 
        .getLocation(LocationManager.NETWORK_PROVIDER); 

      if (nwLocation != null) { 
       double latitude = nwLocation.getLatitude(); 
       double longitude = nwLocation.getLongitude(); 
       Toast.makeText(
         getApplicationContext(), 
         "Mobile Location (NW): \nLatitude: " + latitude 
           + "\nLongitude: " + longitude, 
         Toast.LENGTH_LONG).show(); 

      } else { 
       showSettingsAlert("NETWORK"); 
      } 

     } 
    });
