如何将水平recyclerView连接到垂直recyclerView？

您需要创建一个元素的垂直列表，其中一个元素处于水平位置。因此，需要使用两个recyclerViewAdapter，但问题是不理解这个。它是如何完成的？已经有一个垂直适配器

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

@NonNull
private List<BaseProductsItem> baseProductsItems;
@Nullable
private OnItemClickListener onItemClickListener;

public ProductsAdapter(@NonNull List<BaseProductsItem> baseProductsItems,
                       @Nullable OnItemClickListener onItemClickListener) {
    this.baseProductsItems = baseProductsItems;
    this.onItemClickListener = onItemClickListener;
}

@NonNull
@Override
public RecyclerView.ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
    View view;
    switch (viewType){
        case ProductsType.TITLE:
            view = LayoutInflater.from(parent.getContext())
                    .inflate(R.layout.item_title_products, parent, false);
            return new TitleVH(view);
        case ProductsType.DEPOSIT:
            view = LayoutInflater.from(parent.getContext())
                    .inflate(R.layout.item_deposits_products, parent, false);
            return new DepositVH(view);
        case ProductsType.CREDIT:
            view = LayoutInflater.from(parent.getContext())
                    .inflate(R.layout.item_credits_products, parent, false);
            return new CreditVH(view);
        case ProductsType.DEBIT_CARD:
            view = LayoutInflater.from(parent.getContext())
                    .inflate(R.layout.item_debitcards_products, parent, false);
            return new DebitCardVH(view);
        case ProductsType.CREDIT_CARD:
            view = LayoutInflater.from(parent.getContext())
                    .inflate(R.layout.item_creditcards_products, parent, false);
            return new CreditCardVH(view);
