无法在Recyclerview之间放置广告，使用firebase UI来获取firestore数据。

Question

我的适配器类

public class ShayariAdapter extends FirestoreRecyclerAdapter<ShayariModel, ShayariAdapter.ShayariViewHolder> {

    private OnItemClickListener listener;
    public interface OnItemClickListener {
        void onItemClick(DocumentSnapshot documentSnapshot, int position);
    }

    public void setOnItemClickListener(OnItemClickListener listener) {
        this.listener = listener;
    }

    public ShayariAdapter(@NonNull FirestoreRecyclerOptions<ShayariModel> options) {
        super(options);
    }

    @Override
    protected void onBindViewHolder(@NonNull ShayariViewHolder holder, int position, @NonNull ShayariModel model) {
        holder.body.setText(model.getBody());
        holder.category.setText(model.getCategory());
        holder.author.setText(model.getAuthor());
    }

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


    class ShayariViewHolder extends RecyclerView.ViewHolder {
        TextView body, author;
        TextView category;
        ImageView shareShayari;
        public ShayariViewHolder(@NonNull View itemView) {
            super(itemView);
            body = itemView.findViewById(R.id.shayariText);
            category = itemView.findViewById(R.id.category);
            author = itemView.findViewById(R.id.authorName);
            shareShayari = itemView.findViewById(R.id.shareShayari);

            shareShayari.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    int position = getAdapterPosition();
                    if (position != RecyclerView.NO_POSITION && listener != null) {
                        listener.onItemClick(getSnapshots().getSnapshot(position), position);
                    }
                }
            });
        }
    }
}

我无法在recyclerview项目之间添加广告，因为有简单的适配器教程，但找不到FirebaseUI Recyclerview适配器的教程。

我已经尝试了google codelab教程，但卡在getItemViewType。尝试了许多事情，并卡在这个

FirebaseUI不允许你改变用于渲染视图的数据。 它只是一个非常简单的方式来开始将数据从Firestore显示到RecyclerView中。 如果你有更高级的情况，需要添加或修改查询结果，你将需要建立自己的适配器。
