安卓回收商视图不显示项目

我想在我的回收商视图中显示这些项目，但它根本没有显示，我看不到错误。也许你们可以帮我。

主要活动.java

    RecyclerView recyclerView = (RecyclerView)findViewById(R.id.rec);
List<MenuData> list = new ArrayList<>();
        recyclerView.setHasFixedSize(true);
        LinearLayoutManager linearLayoutManager = new LinearLayoutManager(this);
        linearLayoutManager.setOrientation(LinearLayoutManager.VERTICAL);
        recyclerView.setLayoutManager(linearLayoutManager);

        MenuRecAdapter menuRecAdapter = new MenuRecAdapter(list);
        recyclerView.setAdapter(menuRecAdapter);

回收器查看适配器：

    public class MenuRecAdapter extends RecyclerView.Adapter<RecViewHolder>{

    private List<MenuData> mList;
    Activity context;

    public MenuRecAdapter(List<MenuData> mList){
        this.mList = mList;
    }

    public int getItemCount(){
        return mList.size();
    }

    public RecViewHolder onCreateViewHolder(ViewGroup viewGroup, int position){

        View v = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.menuitem, viewGroup, false);
        RecViewHolder pvh = new RecViewHolder(v);
        return pvh;
    }

    public void onBindViewHolder(RecViewHolder holder, int i){
        holder.menuTeXT.setText(mList.get(i).text);
    }

    @Override
    public void onAttachedToRecyclerView(RecyclerView recyclerView) {
        super.onAttachedToRecyclerView(recyclerView);
    }

}

项目视图持有者：

  public class RecViewHolder extends RecyclerView.ViewHolder {

    public TextView menuTeXT;

    public RecViewHolder(View itemView){
        super(itemView);

        menuTeXT = (TextView)itemView.findViewById(R.id.menuTXT);
    }
}

以及我想放入回收器视图的数据（未显示的数据）：

    class MenuData {

    String text;

    MenuData(String text){
        this.text = text;
    }

    private List<MenuData> list;

    private void initializeData(){
        list = new ArrayList<>();
        list.add(new MenuData("Featured"));
        list.add(new MenuData("Categories"));
        list.add(new MenuData("Sell"));
        list.add(new MenuData("Settings"));
        list.add(new MenuData("Logout"));
    }

}
