在FirestoreRecyclerAdapter上用接口实现onLongClick

public interface OnItemLongClickListener {
    void onItemLongClick(DocumentSnapshot documentSnapshot, int position);
}

private OnItemLongClickListener onItemLongClickListener;

public void setOnItemLongClickListener(OnItemLongClickListener listener) {
    this.onItemLongClickListener = listener;
}

@Override
protected void onBindViewHolder(@NonNull ViewHolder holder, int position, @NonNull Model model) {
    // 设置列表项视图的数据

    holder.itemView.setOnLongClickListener(new View.OnLongClickListener() {
        @Override
        public boolean onLongClick(View v) {
            if (onItemLongClickListener != null) {
                onItemLongClickListener.onItemLongClick(getSnapshots().getSnapshot(position), position);
            }
            return true;
        }
    });
}

adapter.setOnItemLongClickListener(new OnItemLongClickListener() {
    @Override
    public void onItemLongClick(DocumentSnapshot documentSnapshot, int position) {
        // 处理长按操作
    }
});
