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？

Research direction
The issue centers on ViewHolder.get(Context, View convertView, ...), with the relevant recycling and tag lookup shown in the report. Start by tracing how ListView supplies recycled views and how the holder is stored and retrieved; done means the intended lookup path is confirmed and the reported behavior is covered by a test or clearly documented.
Written by the indexing model from the issue text.
Description
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;
}
