完全州名を公式州住所コードに変換する必要があります。たとえば、String New Yorkの場合、私はNYを制作する必要があります。これをすべてハッシュマップに入れることができましたが、これにはユーティリティが必要ですか？私はAndroid環境にいます。私はこの1つのutilのためだけに大きなライブラリをインポートしたくないです。ありがとう米国の州名を州コードに変換するUtilはありますか？例えば。アリゾナ州からアリゾナ州へ？
私はそれが既製持っている - あなたはそれを使用することができます。

私はあなたが私を救った入力の量のためにこれを100倍upvoteすることができたらいいと思う。アルファベット順を維持するために、HashMapをLinkedHashMapに変更することをお勧めします。 –
ソート順を維持する私の以前のコメントは、元の質問の観点からはあまり意味がないと思います。私はこのリストにUIのドロップダウンを入力したいと思っていました。 –
カナダの州もいくつか追加しました。 OPは米国の州の名前を尋ねている。 – Hamdi
コードと値を使ってMap<String, String>をビルドします。これは簡単で、データはほとんどありません。このための「ユーティリティ」はありません。構築するアプリケーションに固有のものです。
私はそうは思わない（少なくとも私は聞いたことがない）。しかし、あなたはいつもそれを達成するために辞書を使うことができます。
私は、最も簡単な方法はHashMapであると思います。たとえそれを変換するライブラリがあったとしても、おそらく同じものを使うでしょう。
Map<String, String> states = new HashMap<String, String>();
states.put("Arizona", "AZ");
states.put("California", "CA");
// So on and so forth...
// Then you could create a method like
public String toStateCode(String s) {
return states.get(s);
}
私はこの質問に答えていない知っているが、念のために誰かが反対のことを必要とする：州/地方を使用しますキーとしての省略形と値としての名前。地図を再フォーマットするのに数分かかりました。また、受け入れられた答えのQuebecの略語は間違っています。

あなたもカナダの州をいくつか追加しました。 OPは米国の州の名前を尋ねている。 – Hamdi
私はカナダの州が必要でした。それらを含めることを傷つけない。 –
あなたはおそらくこのために共用ライブラリで一緒に作業しているはずですが、正確な名前で投稿/スレッドを続ける努力を賞賛します。 –
