我需要把手放在列表中的屬性上。

所以應該是功能->屬性-> name_en(類似對象的列表)

我嘗試這樣：

JSONParser parser = new JSONParser();

Object obj = parser.parse(Json_str);

JSONObject jsonObject = (JSONObject) obj;

JSONArray jsonFeaturesArr = new JSONArray(jsonObject.getJSONArray("features"));

為了創建第一個Json Array，但我什至無法做到。我收到錯誤消息：JSONObject類型的方法getJSONArray(String)未定義

(我對“ getJSONObject”有同樣的錯誤)。一定是缺少的東西，我是Java / android新手。

如果我解決錯誤，該如何深入Json？

提前感謝幫助。
