Integer値からString PlaceTypeを取得する方法は？

Question

Google Places APIを初めて習得しました。この問題の解決策を探しています。

私のアプリの最初の部分では、私は現在の場所のplaceTypesを取得したいと思います。私はそれを成功させましたが、Integer値のリストを返します。これは、異なるPlace.TYPE_ *に関連付けられます。

私の全体的な目標は、私の場所の現在の場所タイプを取得し、次にURL経由でPlaceSearchを行うことです。これを行うには、私は自分のURLに挿入できるように、文字列型に私の場所のリスト内の整数を変換する必要があります。

注：URLに "レストラン"という単語だけでなく "レストラン"の整数値を挿入しようとしましたが、代わりにホテル、オフィスビルなど間違った結果を返しました。 。

例えば、私のURLは次のようになります。

https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=" + lat + "," + lng+"&radius=2000&type=restaurant&key=my_key 

お知らせURL内の単語 "レストラン"。それがInteger値で置き換えられ、正しい結果が返されませんでした。

[EDITED]

あなたはこれを試すことができます。

private String getPlaceTypeForValue(int value) throws Exception { 
    Field[] fields = Place.class.getDeclaredFields(); 
    String name; 
    for (Field field : fields) { 
     name = field.getName().toLowerCase(); 
     if (name.startsWith("type_") && field.getInt(null) == value) { 
      return name.replace("type_", ""); 
     } 
    } 
    throw new IllegalArgumentException("place value " + value + " not found."); 
} 

私はそれを検証するテストを作成し、ちょうどいくつかの種類が欠落し、動作するはずです：administrative_area_level_4、administrative_area_level_5、postal_code_suffixとstreet_number。

整数型は、それが常に文字列として呼ばのドキュメントで、どこから来ている私は理解していませんでした。

タイプ - 結果を指定したタイプに一致する場所に限定します。指定できるタイプは1つだけです（複数のタイプが指定されている場合、最初の入力に続くすべてのタイプは無視されます）。 list of supported typesを参照してください。
