无法更新ListView中的不同行

Question

我已根据此link创建了一个示例，该示例在ListView中的几行中具有不同的布局。这是布局

由于我只希望第一行有不同的布局，每当位置为零时我都应用布局一（姓名和电话），其余我应用布局二（地址）。

我遇到的问题是当我在适配器上触发notifyDataSetChanged时，只有我的地址被更改但名称＆amp;电话行即第一行不更新。我在选择子菜单项时触发notifyDataSetChanged。

这是代码。

public static final int TYPE_ADDRESS = 1;
public static final int TYPE_NAME = 0;
public static final int TYPE_MAX_COUNT =2;

@Override
public int getItemViewType(int position) {
    if(position == 0)
        return TYPE_NAME;
    else
        return TYPE_ADDRESS;
}
@Override
public int getViewTypeCount() {
    return TYPE_MAX_COUNT;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {


    ViewHolder holder=null;
    int type = getItemViewType(position);
    System.out.println("getView " + position + " " + convertView + " type = " + type);




 if (convertView == null) {
     holder = new ViewHolder();


    switch (type) {
        case TYPE_ADDRESS:
                    convertView = mInflater.inflate(R.layout.layout_address, null);
                    holder.address = (TextView) convertView.findViewById(R.id.address_id);                  
                    holder.address.setText(data.getAddress(position));


                    break;

        case TYPE_NAME:                        
                    convertView = mInflater.inflate(R.layout.layout_name, null);                    
                    holder.name = (TextView)convertView.findViewById(R.id.name_id);
                    holder.phone = (TextView)convertView.findViewById(R.id.phone_id);



                    holder.name.setText(data.getName(position));
                    holder.phone.setText(data.getPhone(position));




                    break;
    }

        convertView.setTag(holder);          

   }else {

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



    return convertView;
}



static class ViewHolder {
        TextView address;
        TextView name;
        TextView phone;

    }

AFAIK，您需要在if (convertView == null){}else{}块之外管理视图（如设置文本），因为您无论如何都需要调用它，而不仅仅是视图创建。这可能是问题吗？

if (convertView == null) {
     holder = new ViewHolder();


    switch (type) {
        case TYPE_ADDRESS:
                    convertView = mInflater.inflate(R.layout.layout_address, null);
                    holder.address = (TextView) convertView.findViewById(R.id.address_id);                                     

                    break;

        case TYPE_NAME:                        
                    convertView = mInflater.inflate(R.layout.layout_name, null);                    
                    holder.name = (TextView)convertView.findViewById(R.id.name_id);
                    holder.phone = (TextView)convertView.findViewById(R.id.phone_id);

                    break;
    }

        convertView.setTag(holder);          

   }else {

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

   switch (type) {
        case TYPE_ADDRESS:
              holder.address.setText(data.getAddress(position));
              break;
        case TYPE_NAME:                        
              holder.name.setText(data.getName(position));
              holder.phone.setText(data.getPhone(position)); 
              break;
