I can parse json data to my recyclerview. but when i meet json that has array data in it, my app forceclose when i try to get that. How to solve this? or anyone has similar sample code with this case?

                progressBar.setVisibility(View.GONE);

                nodeApi resource = response.body();
                List<nodeApi.steps_count> dataList = resource.steps_count;

                Adapter_meeting rv_adapter = new Adapter_meeting(dataList, Activity_Stepcounter.this);
                rv.setLayoutManager(new LinearLayoutManager(Activity_Stepcounter.this));
                rv.setAdapter(rv_adapter);
                rv.hasFixedSize();
                rv_adapter.notifyDataSetChanged();
            }

            @Override

On these lines:

holder.tv_tanggalEvent.setText(mitem_meeting.get(position).getStartTimeMillis());
holder.tv_lokasiEvent.setText(mitem_meeting.get(position).getStartTime());
holder.tv_waktuEvent.setText(mitem_meeting.get(position).getEndTime());

Compilator thinks, that you are passing String resource, but you are actually passing simple String. Just add "" and it should start working.

holder.tv_tanggalEvent.setText(mitem_meeting.get(position).getStartTimeMillis() "");    
holder.tv_namaEvent.setText(mitem_meeting.get(position).getStartTime() "");
holder.tv_waktuEvent.setText(mitem_meeting.get(position).getEndTime() "");

You should pass text to textviews in form of String resource with placeholders, but it doesn't really make sense, when you don't pass there anything except the changing value.

CodePudding user response：

holder.tv_namaEvent.setText(mitem_meeting.get(position).getValue());

You are trying to set Int. Try:

String value = String.valueOf(mitem_meeting.get(position).getValue());
holder.tv_namaEvent.setText(value);

Please check all fields for null and read about name convention in Android :)

Also time in milis should be stored in Long type. You can also read about Kotlin language, mvvn pattern etc.

Thanks, i got help from discord

I have to make jsonresponse first and then convert it to arraylist using nodeApi.java.

public class JsonResponse {
    private nodeApi[] steps_count;

    public nodeApi[] getStep_count() {
        return steps_count;
    }

    public void setnodeApi(nodeApi[] step_count) {
        this.steps_count = step_count;
    }
}

Activity_Stepcounter.java

 Call<JsonResponse> call = jsonPlaceHolderApi.getStep();
        call.enqueue(new Callback<JsonResponse>() {
            @Override
            public void onResponse(Call<JsonResponse> call, Response<JsonResponse> response) {
                progressBar.setVisibility(View.GONE);

                JsonResponse jsonResponse = response.body();
                listStep = new ArrayList<>(Arrays.asList(jsonResponse.getStep_count()));


                Adapter_meeting rv_adapter = new Adapter_meeting(listStep, Activity_Stepcounter.this);
                rv.setLayoutManager(new LinearLayoutManager(Activity_Stepcounter.this));
                rv.setAdapter(rv_adapter);
                rv.hasFixedSize();
                rv_adapter.notifyDataSetChanged();
            }

            @Override
            public void onFailure(Call<JsonResponse> call, Throwable t) {
                call.cancel();
            }
        });

**there are some refactor/rename.
