    View rowView = convertView;
    ContactStockView sv = null;

        // Get a new instance of the row layout view
        LayoutInflater inflater = activity.getLayoutInflater();
        rowView = inflater.inflate(
                R.layout.activity_row, null);

        // Hold the view objects in an object,

        protected TextView number;
        protected ImageButton btncall;
    }

推荐答案

您应该声明字符串数量即可。变化

you should declare the string number in get view method not outside it. change

number=currentStock.getNumber();

到

final String number=currentStock.getNumber();

和删除串（即数）禁区外getview方法

and delete the string(ie,number) from outside getview method
