国家/地区代码未从 Android 中的国家/地区代码选择器获取

Question

我正在 Android 应用程序中开发注册活动。 我想显示国家/地区电话代码（从设备获取国家/地区）。 它可以显示包含国旗、国家电话代码、国家名称的国家列表。 我从https://github.com/mukeshsolanki/country-picker-android获取国家代码选择器的代码。 它包含完整的代码。 我想设置默认国家是在手机里。

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

当我使用这个代码时，我得到了国家代码“in”。 但我想显示电话代码和标志，姓名。 当我打开屏幕。 我想自动显示它。

我的代码如下所示

Answer 1

尝试使用 Lat, long 获取国家/地区代码

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);
    }

Answer 2

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

Answer 3

你可以使用这个库点击这里然后你可以做到这一点

 new DialogPlusBuilder().blurBackground()
               .buildCountriesListDialog(true,new DialogPlus.CountriesDialogListener() {
                   @Override
                   public void onItemClicked(CountryDataModel countryDataModel, DialogPlus dialogPlus) {
                       super.onItemClicked(countryDataModel, dialogPlus);
                       Toast.makeText(MainActivity.this,countryDataModel.getName()+ countryDataModel.getPhone_code(), Toast.LENGTH_SHORT).show();
                   }
               })
               .show(this.getSupportFragmentManager(), "Countries List Dialog");
