Respons JSON tidak dapat dibaca di kelas adaptor tetapi terlihat di logcat menggunakan pustaka http retrofit

Saya telah mengikuti panduan dari https://www.androidhive.info/2016/05/android-working-with-retrofit-http-library/ untuk mendapatkan respons json. Namun responsnya tidak muncul di RecyclerView setelah diurai pada kelas Adaptor. Namun respon JSON terlihat di logcat yang saya buat. Silakan periksa skrip saya di bawah ini:

EkonomiFragment.java

final RecyclerView recyclerView = (RecyclerView) rootView.findViewById(R.id.recyclerViewEkonomi);
    recyclerView.setLayoutManager(new LinearLayoutManager(getContext().getApplicationContext()));

    ApiInterface apiService = ApiClient.getClient().create(ApiInterface.class);

    Call<EkonomiResponse> call = apiService.getEkonomi(rssUrlE);
    call.enqueue(new Callback<EkonomiResponse>(){
        @Override
        public void onResponse(Call<EkonomiResponse> call, Response<EkonomiResponse> response){
            List<Ekonomi> ekonomis = response.body().getItems();
            for(int x=0; x<ekonomis.size(); x++){
                Log.i("Judul", ekonomis.get(x).getTitle());
            }
            Log.d(TAG, "JSON Ekonomi: " + ekonomis);

            //Toast.makeText(rootView.getContext(), "Berhasil", Toast.LENGTH_LONG).show();
            recyclerView.setAdapter(new EkonomiAdapter(ekonomis, R.layout.list_item_berita_e, rootView.getContext()));
            //recyclerView.setAdapter(new EkonomiAdapter(ekonomis, R.layout.list_item_berita_e, rootView.getContext()));
        }

        @Override
        public void onFailure(Call<EkonomiResponse> call, Throwable t) {
            // Log error here since request failed
            Log.e(TAG, t.toString());
            Toast.makeText(rootView.getContext(), "Gagal", Toast.LENGTH_LONG).show();
        }
    });

EkonomiAdapter.java

public class EkonomiAdapter extends RecyclerView.Adapter<EkonomiAdapter.EkonomiViewHolder>{

private List<Ekonomi> ekonomis;
private int rowLayout;
private Context context;

public static class EkonomiViewHolder extends RecyclerView.ViewHolder {
    CardView ekonomiLayout;
    TextView newsTitle;
    TextView pubDate;
    WebView newsDescription;

    public EkonomiViewHolder(View v) {
        super(v);
        ekonomiLayout = (CardView) v.findViewById(R.id.berita_layout_e);
        newsTitle = (TextView) v.findViewById(R.id.title_e);
        pubDate = (TextView) v.findViewById(R.id.pubDate_e);
        newsDescription = (WebView) v.findViewById(R.id.description_e);
    }
}

public EkonomiAdapter(List<Ekonomi> ekonomis, int rowLayout, Context context) {
    this.ekonomis = ekonomis;
    this.rowLayout = rowLayout;
    this.context = context;
}

@NonNull
@Override
public EkonomiViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
    View view = LayoutInflater.from(parent.getContext()).inflate(rowLayout, parent, false);
    return new EkonomiViewHolder(view);
}

@Override
public void onBindViewHolder(@NonNull EkonomiViewHolder holder, int position) {
    Log.i("JSON", ekonomis.get(position).getTitle());
    holder.newsTitle.setText(ekonomis.get(position).getTitle());
    holder.pubDate.setText(ekonomis.get(position).getPubDate());
    holder.newsDescription.getSettings().setJavaScriptEnabled(true);
    holder.newsDescription.loadData(ekonomis.get(position).getDescription(), "text/html; charset=utf-8", "UTF-8");
}

@Override
public int getItemCount() {
    return 0;
} }
