        View view = convertView;





        LayoutInflater li = (LayoutInflater) con
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        if(convertView == null)
        {
            view = li.inflate(R.layout.subbalancedetailsnew, parent, false);
            holder = new ViewHolder();

            view.setTag(holder);
        }
        else
        {
            holder =(ViewHolder)view.getTag();

        }

Answer 1

首先，您必须在textview中设置该值，并且需要调用notifyDataSetChanged（）;通知您的适配器类。

或者您可以使用更新的值更新ArrayList并调用notifyDataSetChanged（）;如果您使用任何ArrayList来设置适配器。

Answer 2

尝试：

((TextView)yourListView.getChildAt(position).findViewById(R.id.yourTextView)).setText("your text");

如何使用基准适配器更新listview中的当前textview值行
