Вы можете сделать это довольно легко с Gson и вот хороший учебник youtube

Вот небольшой пример кода 

    public void getFromServer(){
    final String url =YOUR URL HERE
    final ArrayList<ElementEntity> arrayOfCities = new ArrayList<>();

    // prepare the Request
    final JsonArrayRequest getRequest = new JsonArrayRequest(Request.Method.GET,url,null,
            new Response.Listener<JSONArray>()
            {
                @Override
                public void onResponse(JSONArray response) {
                    // display response
                    Log.d("Response", response.toString());

                    for(int i = 0; i< response.length();i++){
                        try {
                            JSONObject jresponse = response.getJSONObject(i);
                            YourObject yourObject = gson.fromJson(jresponse.toString(),YourObject .class);
                            arrayOfYourObject.add(yourObject);
                        } catch (JSONException e) {
                            e.printStackTrace();
                        }
                    }
                }
            },
            new Response.ErrorListener()
            {
                @Override
                public void onErrorResponse(VolleyError error) {
                    Log.d("Error.Response", "error");
                }
            });

    // add it to the RequestQueue
    queue.add(getRequest);
}
...
