java - 解析 json 对象并附加到 recyclerview

Question

我刚刚开始学习java和Android，我正在尝试解析json数据并将数据应用到recyclerview，但我无法做到这一点。这是我的代码

public void JSON_DATA_WEB_CALL(){

        jsonArrayRequest = new JsonArrayRequest(GET_JSON_DATA_HTTP_URL,

                new Response.Listener<JSONArray>() {
                    @Override
                    public void onResponse(JSONArray response) {
                    progressBar.setVisibility(View.INVISIBLE);
                        JSON_PARSE_DATA_AFTER_WEBCALL(response);
                    }
                },
                new Response.ErrorListener() {
                    @Override
                    public void onErrorResponse(VolleyError error) {

                    }
                });

        requestQueue = Volley.newRequestQueue(this);

        requestQueue.add(jsonArrayRequest);
    }

    public void JSON_PARSE_DATA_AFTER_WEBCALL(JSONArray array){

        for(int i = 0; i<array.length(); i++) {

            GetDataAdapter GetDataAdapter2 = new GetDataAdapter();

            JSONObject json = null;
            try {

                json = array.getJSONObject(i);

                GetDataAdapter2.setImageTitleNamee(json.getString(JSON_IMAGE_TITLE_NAME));
                //GetDataAdapter2.setImageServerLarger(json.getString(JSON_IMAGE_LARGER));

                GetDataAdapter2.setImageServerUrl(json.getString(JSON_IMAGE_URL));
                GetDataAdapter2.setMrp_price(json.getString(JSON_MRP_PRICE));
                GetDataAdapter2.setDisc_price(json.getString(JSON_DISC_PRICE));

            } catch (JSONException e) {

                e.printStackTrace();
            }
            GetDataAdapter1.add(GetDataAdapter2);
        }

        recyclerViewadapter = new RecyclerViewAdapter(GetDataAdapter1, this);

        recyclerView.setAdapter(recyclerViewadapter);
    }

这是我的 JSON 响应

{"118":{"garment_color":"Blue","garment_name":"skjhkds","garment_price":"232"},"119":{"garment_color":"hjsadjjs","garment_name":"sdasd","garment_price":"23478"}}

请有人简要解释一下正确的代码。这将会非常有帮助。谢谢

Answer 1

rvAdapter = new RvAdapter(getActivity());
recyclerview.setAdapter(rvAdapterHScode);
rvAdapter.set(responce.getcodes());
recyclerview.setLayoutManager(new GridLayoutManager(getActivity(), 3));

然后在适配器中接受设定值或

在 recyclerview 适配器中调用您的响应
