What is the purpose of the hasStableIds method in BaseAdapter?

according to this article and Stackoverflow , when hasStableIds returns false, when adapter calls notifyDataSetChanged () , it will decide whether to refresh Item, based on the change of ID returned in getItemId . That is to say, it has a local refresh effect. But I tried, and whether hasStableIds returns true or false, the getView method is called to refresh all visible layouts. So what exactly is the purpose of hasStableIds ?
