android - listview recyclerview 问题？

Question

我有一个 ListView ，其中我有一个 View ，我已经为其设置了可见性。现在在按钮上单击此 ListView 的子元素之一我想显示此 View ，但它显示在多个位置listview。我知道这是由于回收 View 造成的，但我无法为其实现解决方案。有人有建议吗，这是我的代码

if(convertView == null)
    {
        convertView = inflator.inflate(R.layout.fragment_open_orders_row, null);
        fulfilledView = new FulFilledOrdersHolder();

        fulfilledView.title = (TextView) convertView.findViewById(R.id.tv_open_order_title);
        fulfilledView.order_datetime = (TextView) convertView.findViewById(R.id.tv_open_order_datetime);
        fulfilledView.customer_address = (TextView) convertView.findViewById(R.id.tv_open_order_address);
        fulfilledView.customer_name = (TextView) convertView.findViewById(R.id.tv_open_order_name);
        fulfilledView.product_price = (TextView) convertView.findViewById(R.id.tv_open_order_price);

        fulfilledView.product_image = (ImageView) convertView.findViewById(R.id.imv_open_orders);

        fulfilledView.details = (Button) convertView.findViewById(R.id.button_open_orders_details);
        fulfilledView.call = (Button) convertView.findViewById(R.id.button_open_orders_call);

        fulfilledView.slide = (RelativeLayout) convertView.findViewById(R.id.sliding);
        fulfilledView.slide.setVisibility(View.GONE);
        convertView.setTag(fulfilledView);
    }
    else
    {
    fulfilledView = (FulFilledOrdersHolder) convertView.getTag();
    }

    fulfilledView.title.setText(values.get(position).getTitle());
    fulfilledView.order_datetime.setText(values.get(position).getOrder_datetime());


    fulfilledView.details.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

                fulfilledView.slide.setVisibility(View.VISIBLE);

        }
    });

Answer 1

尝试在默认值为 false 的列表项模型类中添加一个 bool 标志:

private boolean isSlideVisible;

public boolean isSlideVisible() {
   return isSlideVisible;
}

public void setSlideVisible(boolean isSlideVisible) {
    this.isSlideVisible = isSlideVisible;
}

现在更改特定项目的标志反之状态并通知适配器:

fulfilledView.details.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
      if(values.get(position).isSlideVisible()){
         values.get(position).setSlideVisible(false);
      }else{
         values.get(position).setSlideVisible(true);      
      }
      notifyDataSetChanged ()
    }
 });

根据标志值显示幻灯片 View :

if(values.get(position).isSlideVisible()){
   fulfilledView.slide.setVisibility(View.VISIBLE);
}else{
   fulfilledView.slide.setVisibility(View.GONE);
}
