Как добавить один дополнительный элемент-заголовок в RecyclerView?

class MyRecyclerAdapter extends RecyclerView.Adapter<BillRecyclerAdapter.ViewHolder>{
 
    Context ctx;
    private List<ProductCatalog> list;
 
    public MyRecyclerAdapter(Context context, List<ProductCatalog> list){
        this.ctx=context;
        this.list=list;
    }
 
 
    @Override
    public MyRecyclerAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
 
        View v = LayoutInflater.from(ctx).inflate(R.layout.item,parent,false);
        BillRecyclerAdapter.ViewHolder vh = new MyRecyclerAdapter.ViewHolder(v);
        return vh;
    }
 
    @Override
    public void onBindViewHolder(ViewHolder holder, int position) {
        ProductCatalog pc = list.get(position);
 
        holder.name.setText(pc.name);
        holder.count.setText(pc.count);
        holder.price.setText(pc.price);
 
    }
 
 
    @Override
    public int getItemCount() {
        return list.size();
    }
 
    public static class ViewHolder extends RecyclerView.ViewHolder{
 
        private TextView name;
        private TextView count;
        private TextView price;
 
        public ViewHolder(View itemView) {
            super(itemView);
            name=(TextView)itemView.findViewById(R.id.name);
            count=(TextView)itemView.findViewById(R.id.count);
            price=(TextView)itemView.findViewById(R.id.price);
        }
    }
 
}

RecyclerView mRecyclerView = (RecyclerView)findViewById(R.id.recyclerview);
mRecyclerView.setHasFixedSize(true);
LinearLayoutManager mLayoutManager = new LinearLayoutManager(this);
mRecyclerView.setLayoutManager(mLayoutManager);
MyRecyclerAdapter mAdapter = new MyRecyclerAdapter(this, list);
mRecyclerView.setAdapter(mAdapter);
