Не показывать элементы в RecyclerView: RecyclerView: адаптер не подключен; пропускающий макет

Question

это мой код для Показать элементы категории:

public class CategoryFragmentBehavior extends FragmentBehavior {

    protected RecyclerView recyclerView;
    protected RVOutCategoryAdapter rvOutCategoryAdapter;
    protected int index;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        bundle = getArguments();
        return inflater.inflate(R.layout.tab_cat_1, container, false);
    }

    @Override
    public void onActivityCreated(@Nullable Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
        init();
    }

    protected void init() {
        super.init();

        recyclerView = (RecyclerView) activity.findViewById(R.id.rv);
        TabHome.btnCountRV.setVisibility(View.GONE);
        id = bundle.getInt(Variables.CART_ID);
        TabHome.setTvBreadcrumbs(bundle.getString(Variables.CART_TITLE), index);
    }
}

На первой вкладке категории материал отображается хорошо. это мой код на первой вкладке:

public class TabCat1 extends CategoryFragmentBehavior {

    private List<HiModel.CategoryParent> categorySub1ListBeen;

    public static TabCat1 newInstance() {
        TabCat1 fragment = new TabCat1();
        return fragment;
    }

    protected void init() {
        index = 0;
        super.init();

        categorySub1ListBeen = GlobalVariable.newInstance().getHiModel().getCategorySub1List();
        categorySub1ListBeen = ToolsBehavior.getFilterList(id, categorySub1ListBeen);

        if (categorySub1ListBeen.size() > 0)
            initRVOutCategory();
        else
            showWallDialog(getString(R.string.coming_soon), R.drawable.ic_folder_open_blue_50_48dp);
    }

    private void initRVOutCategory() {

        rvOutCategoryAdapter = new RVOutCategoryAdapter(activity, categorySub1ListBeen, new RVOutCategoryAdapter.CallBack() {
            @Override
            public void onItemClick(int position, View view) {
                HiModel.CategoryParent categoryParent = categorySub1ListBeen.get(position);
                TabHome.TabController(categoryParent, index);
            }
        });

        recyclerView.setLayoutManager(new LinearLayoutManager(activity));
        recyclerView.setAdapter(rvOutCategoryAdapter);
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        TabHome.setTvBreadcrumbs("", 0);
    }
}

Когда я нажимаю на элемент, отображается вторая вкладка, но элементы не отображаются. это мой код на второй вкладке:

public class TabCat2 extends CategoryFragmentBehavior {

    private List<HiModel.CategoryParent> categorySub2ListBeen;

    public static TabCat2 newInstance() {
        TabCat2 fragment = new TabCat2();
        return fragment;
    }

    protected void init() {
        index = 1;
        super.init();

        categorySub2ListBeen = GlobalVariable.newInstance().getHiModel().getCategorySub2List();
        categorySub2ListBeen = ToolsBehavior.getFilterList(id, categorySub2ListBeen);

        if (categorySub2ListBeen.size() > 0)
            initRVOutCategory();
        else
            showWallDialog(getString(R.string.coming_soon), R.drawable.ic_folder_open_blue_50_48dp);
    }

    private void initRVOutCategory() {
        rvOutCategoryAdapter = new RVOutCategoryAdapter(activity,categorySub2ListBeen, new RVOutCategoryAdapter.CallBack() {
            @Override
            public void onItemClick(int position, View view) {
                HiModel.CategoryParent categoryParent = categorySub2ListBeen.get(position);
                TabHome.TabController(categoryParent, index);
            }
        });

        recyclerView.setLayoutManager(new LinearLayoutManager(activity));
        recyclerView.setAdapter(rvOutCategoryAdapter);
    }
}

это мой адаптер Код:

public class RVOutCategoryAdapter extends RecyclerView.Adapter<RVOutCategoryAdapter.MyViewHolder> {

    private Context mContext;
    private List<HiModel.CategoryParent> categoryParents;

    private CallBack callBack;

    public interface CallBack {
        void onItemClick(int position, View view);
    }

    public class MyViewHolder extends RecyclerView.ViewHolder {

        protected TextView tvTitle;

        public MyViewHolder(final View view) {
            super(view);

            tvTitle = (TextView) view.findViewById(R.id.tv);
        }
    }

    public RVOutCategoryAdapter(Context mContext, List<HiModel.CategoryParent> categoryParents, CallBack callBack) {
        this.mContext = mContext;
        this.callBack = callBack;
        this.categoryParents = categoryParents;
    }

    public void setmContext(Context mContext) {
        this.mContext = mContext;
    }


    @Override
    public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_out_category, parent, false);
        return new MyViewHolder(itemView);
    }

    @Override
    public void onBindViewHolder(MyViewHolder holder, final int position) {
        HiModel.CategoryParent categorySub1ListBean = categoryParents.get(position);

        holder.setIsRecyclable(false);

        holder.tvTitle.setText(categorySub1ListBean.getName());
        holder.itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                callBack.onItemClick(position, v);
            }
        });
    }


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


    public void clear() {
        final int size = categoryParents.size();
        categoryParents.clear();
        notifyItemRangeRemoved(0, size);
    }
}

на Android 7 и ниже, элементы на второй вкладке отображаются хорошо , но не в Android 8. И выдает следующую ошибку:

RecyclerView: No adapter attached; skipping layout

Пожалуйста, помогите мне Спасибо
