Question

我有一个适配器，我试图将联系人详细信息检索到列表视图

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

    View view = convertView; 
    final ViewHolder holder;
    if (view == null) { 
    view = inflater.inflate(R.layout.profile, null); 
    holder = new ViewHolder();
    holder.text = (TextView) view.findViewById(R.id.name);
    holder.textContNo = (TextView) view.findViewById(R.id.contactno);
    holder.textEmailId = (TextView) view.findViewById(R.id.emailId); 
    view.setTag(holder);
    } else
        holder = (ViewHolder) view.getTag();


    Profile contact = listCont.get(position); 
    holder.text.setText(contact.getName()); 

    QuickContactBadge photo = (QuickContactBadge ) view.findViewById(R.id.quickContactBadge1);  
    photo.setTag(contact.getMobileNo()); 
    new LoadImage(photo).execute(contact.getMobileNo());

我在日志中收到了follogin错误

在此行附近获取classcastexception：holder =（ViewHolder）view.getTag（）; 在哪里我做错了，感谢任何帮助

Answer 1

我认为这样的返回类型声明，

return view;

Android：视图持有者的classCastException
