Данные не попадают в RecyclerView

Question

У меня есть два файла XML, один для RecyclerView и один для списка.

Я также создал файл java для адаптера и передаю данные через адаптер. но все же я не могу получить какие-либо данные в режиме переработки. Имя файла

RecycleViewAdapter. java

public class RecyclerViewAdapter extends RecyclerView.Adapter<RecyclerViewAdapter.ViewHolder> {

    private ArrayList<String> mUrl = new ArrayList<>();
    private  ArrayList<String> mTitle = new ArrayList<>();
    private ArrayList<String> mThumbnail = new ArrayList<>();
    private ArrayList<String> mArtist = new ArrayList<>();
    private ArrayList<Integer> mDuration = new ArrayList<>();
    private Context mContext;

    public RecyclerViewAdapter(Context mContext, ArrayList<String> mUrl, ArrayList<String> mTitle, ArrayList<String> mThumbnail, ArrayList<String> mArtist, ArrayList<Integer> mDuration) {
        this.mUrl = mUrl;
        this.mTitle = mTitle;
        this.mThumbnail = mThumbnail;
        this.mArtist = mArtist;
        this.mDuration = mDuration;
        this.mContext = mContext;
    }

    @Override
    public ViewHolder onCreateViewHolder( ViewGroup parent, int viewType) {

        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.listitem,parent,false);
        ViewHolder holder = new ViewHolder(view);
        return   holder;
    }

    @Override
    public void onBindViewHolder( ViewHolder holder, int position) {

        holder.url.setText(mUrl.get(position));
        holder.title.setText(mTitle.get(position));
        holder.thumbnail.setText(mThumbnail.get(position));
        holder.artist.setText(mArtist.get(position));
        holder.duration.setText(mDuration.get(position));

    }

    @Override
    public int getItemCount() {
        return mUrl.size();

    }

    public class ViewHolder extends RecyclerView.ViewHolder{

        TextView url,title,thumbnail,artist,duration;
        LinearLayout linear_layout;

        public ViewHolder(@NonNull View itemView) {
            super(itemView);

            url = itemView.findViewById(R.id.url);
            title = itemView.findViewById(R.id.title);
            thumbnail = itemView.findViewById(R.id.thumbnail);
            artist = itemView.findViewById(R.id.artist);
            duration = itemView.findViewById(R.id.duration);
            linear_layout = itemView.findViewById(R.id.linear_layout);
        }
    }
}

Answer 1

После изучения вашего кода, я полагаю, что вы сталкиваетесь с кражей sh при привязке ваших данных к адаптеру переработчика. Вы пытаетесь связать целое число ( Duration ) с TextView, который принимает только строки. Поэтому вы должны использовать String.format следующим образом:

holder.duration.setText(String.format("%d",mDuration.get(position)));

Пожалуйста, проверьте это, и если вы работаете в исключительной ситуации, пожалуйста, опубликуйте его как ответ.
