推荐答案

好问题，这是您的答案 holder.setIsRecyclable(false).

Good Question, this is your answer holder.setIsRecyclable(false).

@Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {

    LayoutInflater inflater = (LayoutInflater) parent.getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View view = inflater.inflate(R.layout.product_recycle_buyer_list_item, parent, false);
    MyViewHolder holder = new MyViewHolder(view);

    holder.setIsRecyclable(false);

    return holder;
}
