Address class getCountryCode() method returns digits

public static Country getCountryFromLocation(Context cxt, List<Country> countryList, Location location, int maxAddress) {
    if (location == null || countryList == null || countryList.isEmpty()) {
        Log.d("ooo", "location == null || countryList == null || countryList.isEmpty()");
        return null;
    }

    double longitude = location.getLongitude();
    double latitude = location.getLatitude();

    Geocoder coder = new Geocoder(cxt);
    try {
        List<Address> addressList = coder.getFromLocation(latitude, longitude, maxAddress);

        for (Address address : addressList) {
            String curCountryCode = address.getCountryCode();

            Log.d("ooo", "address " + address.toString());
            if (TextUtils.isEmpty(curCountryCode)) {
                continue;
            }

            for (Country country : countryList) {
                if (country.countryCode.equals(curCountryCode)) {
                    return country;
                }
            }
        }
    } catch (IOException e) {
        e.printStackTrace();
    }
    return null;
}

I am trying to write a function which will take the longitude and latitude to get the country code which is based on ISO 3166-2. According to the method description on Address class:

/**
 * Returns the country code of the address, for example "US",
 * or null if it is unknown.
 */
public String getCountryCode() {
    return mCountryCode;
}

I should get CN based on the longitude and latitude, but I get address output like this:

 D/ooo: address Address[addressLines=[0:"河南省许昌市鄢陵县",1:"刘桥村"],feature=null,admin=河南省,sub-admin=null,locality=许昌市,thoroughfare=,postalCode=null,countryCode=155,countryName=中国,hasLatitude=true,latitude=34.16667716

155 is what I get for Country Code, please let me know what I should do to get the Country Code from the longitude and latitude. In addition, when I use GeoCoder, it will it returns different 3-digit number even thought input longitudes and latitudes are within the same country, in my case, it's China. 155 for one province, and 131 for another Chinese province..Could you explain what these number stand for ? I am sure it's not country code...

Solution

  • There are many way to getCountry Code in Android.

    1. From Locale Configuration.

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

    It will return country code base on which locale user has configured in device. Ex. I am in India and my device is configured Locale English (United States) then it will return US

    2. From TelephonyManager

    TelephonyManager manager = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);

String CountryID= manager.getSimCountryIso().toUpperCase();

    3. From Latitude/Longitude using GeoCode

    Geocoder geoCoder = new Geocoder(mActivity);
List<Address> addresses = geoCoder.getFromLocation(latitude, longitude, 1);
if (addresses.size() > 0) {
       String CountryID= addresses.get(0).getCountryCode();
}

    NOTE : All method will return country code in 2 letter like US (USA), IN(INDIA)..etc

    Get Country code in digit from letter.

    How to use this array.

    String CountryZipCode="";

String[] rl= getResources().getStringArray(R.array.CountryCodes);
    for(int i=0;i<rl.length;i++){
        String[] g=rl[i].split(",");
        if(g[1].trim().equals(CountryID.trim())){
            CountryZipCode=g[0];
            break;
        }
    }

    NOTE : You can also modify above code for get Country Code in letter from Digit.
