Locale クラスからアイデアを得ることができます。
getAvailableLocales() を呼び出してから、配列を繰り返し処理します- getDisplayCountry() 。その国名を初めて見た場合は、それを展開可能なリストに追加します（例：ArrayListインスタンス）。
例えば。
Javaでは、Java.utilの3つのクラスはすべてAndroidで使用可能です。
import Java.util.*;
class Countries {
public static void main(String[] args) {
Locale[] locales = Locale.getAvailableLocales();
ArrayList<String> countries = new ArrayList<String>();
for (Locale locale : locales) {
String country = locale.getDisplayCountry();
if (country.trim().length()>0 && !countries.contains(country)) {
countries.add(country);
}
}
Collections.sort(countries);
for (String country : countries) {
System.out.println(country);
}
System.out.println( "# countries found: " + countries.size());
}
}
このデスクトップPCでの出力
Albania
Algeria
Argentina
Australia
..
Venezuela
Vietnam
Yemen
# countries found: 95

Locale.getISOCountries（） を使用して、2文字の国コードすべてのリストを取得できます。 2文字の国コードからLocaleオブジェクトを構築し、 Locale.getDisplayName（） を使用して国名を取得できます。
String[] isoCountryCodes = Locale.getISOCountries();
for (String countryCode : isoCountryCodes) {
Locale locale = new Locale("", countryCode);
String countryName = locale.getDisplayCountry();
}
Galaxy Note 3でAndroid 4.3を実行すると、getISOCountries（）は246の国コードを返します。これは、今日（11/24/14）の公式に割り当てられた249のISO国コードにかなり近いです。
GetAvailableLocales（）を呼び出すと、デバイスにインストールされているロケールのみが返されます。このロケールには、ほとんどの国がありません。
私はこのためのクラスを作成しました、それが助けになるかもしれません。

ジオネームWebサービスを使用します。
- 国のリストを取得するには
http://api.geonames.org/countryInfoJSON?username=demo
注：ユーザー名->デモをyour_usernameに変更します
- 国に従って州のリストを取得するには（最初のWebサービス結果のgeonameIdを使用）
エクサ。国がインドの場合、geonameId = 1269750
http://api.geonames.org/childrenJSON?geonameId=1269750&username=demo
- 状態に応じて都市のリストを取得するには（2番目のWebサービス結果のgeonameIdを使用）
エクサ。マハラシュトラ州の場合、geonameId = 1264418
http://api.geonames.org/childrenJSON?geonameId=1264418&username=demo

var normalArray = arrayListOf<Country>()
fun preparedata() {

val locale = Locale("",countryCode)
var countryName: String? = locale.displayCountry
if (countryName == null) {
countryName = "UnIdentified"
}
val simpleCountry = Country(countryName,countryCode)
normalArray.add(simpleCountry)
}
normalArray = ArrayList(normalArray.sortedWith(compareBy { it.countryName }))
}
国はデータクラスです
data class Country(val countryName:String, val countryCode:String){
}
国リストとその詳細を表示するサンプルプロジェクトを次に示します。
@ Ameen Maheen解決策にはいくつかのエラーがあります。国名に従って、正しい国コード ..だから私は国と国コードのリストを修正しました...世界中に24国があります...だから解決策があります:)

public static String[] getCountry() {
return country;
}
public static String[] getCode() {
return code;
}
}
そして、これらのクラスを使用する方法は次のとおりです。
////GETTING THE COUNTRY AND CODE ARRAY ARE AS FOLLOW:-
ArrayList<String> codeArrayList = new ArrayList<String>(Arrays.asList(CountryDetails.getCode()));
ArrayList<String> countryArrayList = new ArrayList<String>(Arrays.asList(CountryDetails.getCountry()));
/////SETTING THE ADAPTER ACCORDING TO THE COUNTRY NAMES
ArrayAdapter<String> adapter = new ArrayAdapter<String>(SignUpScreen.this, Android.R.layout.simple_list_item_1, countryArrayList);
YOUR_LIST_VIEW.setAdapter(adapter);///HERE YOUR_LIST_VIEW IS YOUR LISTVIEW NAME
YOUR_LIST_VIEW.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
Toast.makeText(this,"COUNTRY NAME==>>"+countryArrayList.get(i),Toast.LENGTH_SHORT+" HERE IS THE COUNTY CODE==>>"+codeArrayList.get(i),Toast.LENGTH_SHORT).show();
}
});
