使用FirestoreRecyclerAdapter单击RecyclerView时在新集合中添加项目

public class MyAdapter extends FirestoreRecyclerAdapter<Item, MyAdapter.ViewHolder> {
    private OnItemClickListener listener;

    public MyAdapter(@NonNull FirestoreRecyclerOptions<Item> options, OnItemClickListener listener) {
        super(options);
        this.listener = listener;
    }

    @Override
    protected void onBindViewHolder(@NonNull ViewHolder holder, int position, @NonNull Item model) {
        holder.bind(model);
    }

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

    public interface OnItemClickListener {
        void onItemClick(Item item);
    }

    public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
        private TextView textView;

        public ViewHolder(@NonNull View itemView) {
            super(itemView);
            textView = itemView.findViewById(R.id.textView);
            itemView.setOnClickListener(this);
        }

        public void bind(Item item) {
            textView.setText(item.getName());
        }

        @Override
        public void onClick(View v) {
            int position = getAdapterPosition();
            if (position != RecyclerView.NO_POSITION) {
                Item item = getItem(position);
                listener.onItemClick(item);
            }
        }
    }
}
