The RecylerView items are not showing

I'm trying to implement RecyclerView in an app. I followed the android hive guide but the items won't show. After a lot of checks I still couldn't find the problem.

Do I need to use implementation RecylerView in my build.app I'm using androidX I'm using this RecylcerView in a fragment not activity

My adapter class:

public class CouponsAdapter extends RecyclerView.Adapter<CouponsAdapter.ViewHolder> {
    private List<CouponsModel> couponsList;

    public class ViewHolder extends RecyclerView.ViewHolder {
        private TextView productIds,couponUsage,couponLimit,couponAmount,couponCode,couponType,date;


        public ViewHolder(@NonNull View itemView) {
            super(itemView);
            productIds=(TextView)itemView.findViewById(R.id.products_ids);
            couponUsage=(TextView)itemView.findViewById(R.id.usage_limit);
            couponAmount=(TextView)itemView.findViewById(R.id.coupon_amount);
            couponCode=(TextView)itemView.findViewById(R.id.coupon_code);
            couponType=(TextView)itemView.findViewById(R.id.coupon_type);
            date=(TextView)itemView.findViewById(R.id.date);

        }

    }

public CouponsAdapter (List<CouponsModel> couponsList){
        this.couponsList=couponsList;


}
    @NonNull
    @Override
    public ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        View view= LayoutInflater.from(parent.getContext()).inflate(R.layout.coupons_list,parent,false);


        return new ViewHolder(view);
    }
    @Override
    public void onBindViewHolder(@NonNull ViewHolder holder, int position) {

        CouponsModel couponsModel=couponsList.get(position);
        holder.date.setText(couponsModel.getDate());
        holder.couponType.setText(couponsModel.getCouponType());
        holder.couponCode.setText(couponsModel.getCouponCode());
        holder.couponAmount.setText(couponsModel.getCouponAmount());
        holder.couponUsage.setText(couponsModel.getCouponUsage());
        holder.productIds.setText(couponsModel.getProductIds());

    }

    @Override
    public int getItemCount() {
        if(couponsList.size() == 0)
            return 1;
        return couponsList.size();
    }

My fragment :

  // Inflate the layout for this fragment
        View view= inflater.inflate(R.layout.fragment_coupons, container, false);
        recyclerView=view.findViewById(R.id.coupons_recyler_view);
        couponsAdapter=new CouponsAdapter(couponsModelList);
        recyclerView.setAdapter(couponsAdapter);

        int x=32;
        couponsModelList.add(new CouponsModel(x,x,x,x,"free50","free",x));
        couponsAdapter.notifyDataSetChanged();
        return view;

    }

You are missing Layout-manager .Just add this line to your code.

recyclerView.setLayoutManager(new LinearLayoutManager(this,LinearLayoutManager.VERTICAL,false));

You should set Layout Manager to your RecyclerView.

If layout manager is not set, you will get the following error: No layout manager attached; Skipping layout
