Запрос Gson в RecyclerView

Question

Я хочу установить ответные данные для макета. Я добился успеха, чтобы получить ответ. Как я могу установить данные ответа для определенных полей в программе повторного просмотра? Как я могу установить container_id, заголовок, описание, тег? эти поля находятся внутри в классе модели результата. класс результата находится внутри класса учебной модели. Как я могу найти и установить макет.

Класс фрагмента запроса:

 public void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);
    final ArrayList<Study> todoArrayList = new ArrayList<Study>();

    textView = view.findViewById(R.id.txt_book_name);

    Map<String, String> header = new HashMap<>();
    header.put("Content-Type", "application/x-www-form-urlencoded");

    Map<String, String> params = new HashMap<>();
    params.put("fire", "study-material");
    params.put("job_id", "317");

    RequestQueue requestQueue;
    requestQueue = Volley.newRequestQueue(Objects.requireNonNull(getContext()));

    GsonRequest<Study> gsonRequest = new GsonRequest<>(Request.Method.POST, url, Study.class, header, params,
            new Response.Listener<Study>() {
                @Override
                public void onResponse(Study response) {

List resultList = new ArrayList <> ();

                    Result result = new Result();

                    result.setContent_id(result.getContent_id());
                    result.setTitle(result.getTitle());

                    resultList.add(result);

                    todoArrayList.add(new Study(response.getMessage(),resultList,response.getStatus()));


                    Log.d(TAG, response);

                }
            }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {

            Log.d(TAG,error.toString());
        }
    });

    requestQueue.add(gsonRequest);

    final AdapterForStudy itemsAdapter = new AdapterForStudy(TodoFragment.this.getActivity(), todoArrayList);
    final RecyclerView recyclerView = (RecyclerView) view.findViewById(R.id.recycle);
    GridLayoutManager gridLayoutManager = new GridLayoutManager(TodoFragment.this.getActivity(), 2);
    recyclerView.setLayoutManager(gridLayoutManager);
    recyclerView.setHasFixedSize(true);
    recyclerView.setAdapter(itemsAdapter);
