如何将json数据填充到嵌套的RecyclerView中

Question

如何通过按类别进行翻新，将json中的数据填充到嵌套的RecyclerView中？

我确实尝试使用两个函数通过嵌套的for循环来检索和填充。请给我一些有关如何填充json数据的示例。谢谢

@SuppressLint("WrongConstant")
private void writeRecycler(String jsonresponse) {

    try{
        // Getting the whole Json object from response

        JSONObject obj = new JSONObject(jsonresponse);

        ArrayList<SectionDataModel> sectionDataModelArrayList = new ArrayList<>();
        JSONArray dataArray = obj.getJSONArray("data");

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

            SectionDataModel sectionDataModel = new SectionDataModel();
            JSONObject dataobj = dataArray.getJSONObject(i);

            sectionDataModel.setEqpName(dataobj.getString("equipment"));

            ArrayList<SingleItemDataModel> singleItem = new ArrayList<SingleItemDataModel>();
            for(int j = 0; j<singleItem.size(); j++){
                SingleItemDataModel singleItemDataModel = new SingleItemDataModel();
                JSONObject jobj = dataArray.getJSONObject(j);

                singleItemDataModel.setChecklist(jobj.getString("Checklists"));
                singleItemDataModel.setActivity(jobj.getString("Activity"));
                singleItemDataModel.setStatus(jobj.getString("Status"));
            }
            sectionDataModel.setDescription(singleItem);
            sectionDataModelArrayList.add(sectionDataModel);
        }
