How to call notifyDataSetChanged() from a generic Adapter

An OnItemClickListener for a ListView has the following method:

@Override
public void onItemClick(AdapterView<?> parent, View v, int position, long id)

I'd like to have the adapter behind the ListView refresh, and I believe this is done through the use of:

BaseAdapter.notifyDataSetChanged()

How do I use the parent parameter in the onItemClick method to do this? So far I've tried:

parent.getAdapter().notifyDataSetChanged();

This throws an error because the object returned is of class HeaderViewListAdapter, which for reasons unknown isn't a subclass of BaseAdapter.

Solution

  • AFAIK, there isn't any method in HeaderListView for data refresh/reload. The only way I can think of doing this is to reassign the adapter.
