我正在使用改造来根据其设备填充我的清单活动。数据在 json 文件中。

我确实尝试过这种方法来填充数据，但是只要有类似的类别，它就会填充两次。例如 {Equipment1, checklist1, date1, activity1}, {Equipment1, checklist2, date2, activity2}，它会用不同的清单相应地填充 Equipment1 两次。

下图显示了 DP-03 应该只出现一次并且这 2 个数据需要在一个卡片视图中的错误。

JSONObject obj = new JSONObject(jresponse);
String count = obj.getString("count");

if(!(count.equals("0")))
{


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


    for (int i= 0; i<dataArray.length();i++)
    {
        SectionDataModel sectionDataModel = new SectionDataModel();
        SingleItemDataModel singleItemDataModel = new SingleItemDataModel();
        JSONObject dataobj = dataArray.getJSONObject(i);
        ArrayList<SingleItemDataModel> singleItemDataModelArrayList = new ArrayList<>();

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




            singleItemDataModel.setChecklist(dataobj.getString("Checklists"));
            singleItemDataModel.setActivity(dataobj.getString("Activity"));
            singleItemDataModel.setStatus(dataobj.getString("Status"));
            singleItemDataModel.setTime(dataobj.getString("Date"));

singleItemDataModelArrayList.add(singleItemDataModel);
        sectionDataModel.setDescription(singleItemDataModelArrayList);
        sectionDataModelArrayList.add(sectionDataModel);

     }

    // Create RecyclerView Adapter
    recyclerViewDataAdapter = new RecyclerViewDataAdapter(getContext(), sectionDataModelArrayList);

    // Create the recyclerview
    RecyclerView my_recycler_view = view.findViewById(R.id.my_recycler_view);
    my_recycler_view.setHasFixedSize(true);
    my_recycler_view.setAdapter(recyclerViewDataAdapter);
    my_recycler_view.setLayoutManager(new LinearLayoutManager(view.getContext(), LinearLayoutManager.VERTICAL, false));

}

else
    {
        Toast.makeText(getContext(), "no data", Toast.LENGTH_SHORT).show();

        final AlertDialog.Builder builder = new AlertDialog.Builder(getContext());

        //Set Title
        builder.setTitle("There is no data available");
        builder.setMessage("Please reselect again.");
        builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
            }
        });
        builder.show();
}
} catch (JSONException e) {
    e.printStackTrace();
}
