Question

我在回收站视图中添加了5张卡片。我想在点击它时更改卡片视图的整个视图。但是，只有最后一张卡在点击其中任何一张时才会改变其视图。

我想在点击卡片视图时替换卡片列表布局以替换卡片布局如果有人帮忙，我哪里出错了 ///这是我的适配器::

    @Override
    public void onBindViewHolder(MyViewHolder holder,  int position)
    {
        ItemList itemList = items.get(position);
        holder.companyname.setText(itemList.getCompanyName());
        holder.category.setText(itemList.getCategory());
        holder.idcomp.setText(itemList.getIdcomp());
        holder.udm.setText(itemList.getUdm());
        holder.name.setText(itemList.getName());
    }

    @Override
    public int getItemCount() {
        return items.size();
    }


    public class MyViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener
    {
        public TextView companyname,category,idcomp,udm,name;
        List<ItemList> items=new ArrayList<ItemList>();
        Context context;

        public MyViewHolder(View view, Context context,List<ItemList> items)
        {
            super(view);
            this.items=items;
            this.context=context;
            companyname=(TextView)view.findViewById(R.id.companyname);
            category=(TextView)view.findViewById(R.id.category);
            idcomp=(TextView)view.findViewById(R.id.idcomp);
            udm=(TextView)view.findViewById(R.id.udm);
            name=(TextView)view.findViewById(R.id.name);
            cardlist=(LinearLayout)view.findViewById(R.id.cardlist);
            replacecard=(LinearLayout)view.findViewById(R.id.replacecard);
            view.setOnClickListener(this);


        }

        @Override
        public void onClick(View v) {
            int position=getAdapterPosition();
            ItemList itemList= this.items.get(position);
            cardlist.setVisibility(View.GONE);
            replacecard.setVisibility(View.VISIBLE);

        }
    }
