Need to convert Json

{"1":{"param1":"101","param2":"pamagiti"},"2":{"param1":"102","param2":"pozar0"}}

AT

 Map<String, JSONArray>

Thus, for the key to be 1.2, the value {"param1": "101", "param2": "pamagiti"} and {"param1": "102", "param2": "pozar0"} respectively (in the form of JSONArray )

To do this, try this code

  Type type = new TypeToken<HashMap<String, JSONArray>>(){}.getType(); Map<String, JSONArray> myMap = new Gson().fromJson(JsonString, type); for (Map.Entry<String, JSONArray> param : myMap.entrySet()) { Log.d("com.test.application", "ID " + param.getKey() + " " + param.getValue().toString() ); }

But JSONArray is empty

 ID = 1 [] ID = 2 []

    You do not have an array there, and JSONArray is an array. Therefore, everything is empty. You now have the structure Map<String, Map>
