國家代碼不是從Android中的國家/地區代碼選取器中獲取的

我正在開發Android應用程序中的註冊活動。我想顯示國家的電話代碼（從設備獲取國家）。它可以顯示包含國旗，國家電話代碼，國名的國家列表。我從https://github.com/mukeshsolanki/country-picker-android得到國家代碼選擇器的代碼。它包含完整的代碼。我想在手機中設置默認國家。國家代碼不是從Android中的國家/地區代碼選取器中獲取的

TelephonyManager tm = (TelephonyManager)this.getSystemService(this.TELEPHONY_SERVICE); 
    String countryCodeValue = tm.getNetworkCountryIso(); 
    System.out.println("country = "+country);

當我使用此代碼時，我得到了國家代碼「in」。但我想顯示電話代碼和標誌，名稱。當我打開屏幕。我想自動顯示它。

我的代碼如下所示

看看這個鏈接https://github.com/dlukashev/android-phone-number-with-flags。這可能會幫助你。 –

這可能是一個很好的解決方案：https：//github.com/joielechong/CountryCodePicker/ –

試圖讓國家代碼使用緯度，長

Geocoder geocoder = new Geocoder(context, Locale.getDefault()); 

    try { 
     List<Address> addressList = geocoder.getFromLocation(
       lati, longi, 1); // lati : Latitude ,longi : Longitude 
     if (addressList != null && addressList.size() > 0) { 
      Address address = addressList.get(0); 
      code=addressList.get(0).getCountryCode(); 
      System.out.println("code :: "+addressList.get(0).getCountryCode()); 

     } 
    } catch (IOException e) { 
     Log.e(TAG, "Unable connect to Geocoder", e); 
    }

String locale = context.getResources（）。getConfiguration（）。locale.getCountry（）;
