android - 一行中的按钮单击事件影响android中listview中的其他行

Question

我在 ListView 的每一行都有交付按钮。当我们点击交付按钮时，应该为该特定行项目更改背景图像(图像更改为交付完成图像)。在这里我可以通过编写来更改背景图像代码为 setBackgroundResource。但问题是它会影响 ListView 中的其他行项目，这意味着当我滚动时，它们特定行项目的其他按钮图像也会更改。我从过去三天开始尝试过这个问题，但没有用.请给我建议。

public View getView(final int position, View convertView, ViewGroup parent) {

          ![enter image description here][1]
            final ViewHolder holder;
           holder = new ViewHolder();


           if (convertView == null) {
               LayoutInflater vi = getLayoutInflater();
           convertView = vi.inflate(R.layout.ambassdor_orders_list_fields, null);
           }

           Routes rou=RouteList.get(position);

           holder.route = (Button) convertView.findViewById(R.id.deliverBtn);
           holder.memberName = (TextView) convertView.findViewById(R.id.memberNameTxt);
           holder.amount = (TextView) convertView.findViewById(R.id.amountTxt);

           holder.memberName.setText(rou.getMemberName());
           holder.amount.setText(rou.getAmount());

           holder.route.setTag(position);
           holder.memberName.setTag(position);
           holder.amount.setTag(position);

           convertView.setTag(holder);

           holder.route.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {

                holder.route.setBackgroundResource(R.drawable.done);                          

            }
            });
           convertView.setTag(R.id.routeButtton, holder.route);
           convertView.setTag(R.id.memberNameTxt, holder.memberName);
           convertView.setTag(R.id.amountTxt, holder.amount);
           return convertView;
     }

    public View getView(final int position, View convertView, ViewGroup parent) {

                final ViewHolder holder;
                holder = new ViewHolder();


               if (convertView == null) {
                   LayoutInflater vi = getLayoutInflater();
                   convertView = vi.inflate(R.layout.ambassdor_orders_list_fields, null);

                   convertView.setTag(holder);

               } else {
                   holder = (ViewHolder) convertView.getTag();
               }

               Routes rou=RouteList.get(position);

               holder.route = (Button) convertView.findViewById(R.id.deliverBtn);
               holder.memberName = (TextView) convertView.findViewById(R.id.memberNameTxt);
               holder.amount = (TextView) convertView.findViewById(R.id.amountTxt);

               holder.memberName.setText(rou.getMemberName());
               holder.amount.setText(rou.getAmount());

               holder.route.setOnClickListener(new OnClickListener() {                  public void onClick(View v) {                                  
                          holder.route.setBackgroundResource(R.drawable.done);                          

                }
                });
               return convertView;
         }  

根据您的代码，您应该保留一个字段来表示模型数据本身(路线)中路线按钮背景的状态。以便添加代码以使用此状态切换背景。

当您点击按钮时，只需更新状态(例如 rou.setDone(true))

在您的 getView 中，您可以添加以下代码来更新它

if(rou.getDone()) {
//setBackground
} else {
//revert background
}
notifyDatasetChanged()
