ListView 的 ViewHolder的， 代码里不应该是判mConvertView为空否去new holder吗，通过tag获取也应该是mConvertView吧？

[cervy]

public static ViewHolder get(Context context, View convertView,
ViewGroup parent, int layoutId, int position)
{
if (convertView == null)
{
View itemView = LayoutInflater.from(context).inflate(layoutId, parent,
false);
ViewHolder holder = new ViewHolder(context, itemView, parent, position);
holder.mLayoutId = layoutId;
return holder;
} else
{
ViewHolder holder = (ViewHolder) convertView.getTag();
holder.mPosition = position;
return holder;
}
}
