Android - AutoCompleteTextView how do you append an item to the results list which is always displayed?

Question

I'm trying to append "Not able to find venue click here" to the end of the results list for an AutoCompleteTextView. I need this to display for any results found so that users can add a venue manually

thanks,

andy

try to wrap Adapter in HeaderViewListAdapter and try to use for AutoCompleteTextView

use this constructor

headeradapter= new HeaderViewListAdapter(ArrayList<ListView.FixedViewInfo> headerViewInfos, ArrayList<ListView.FixedViewInfo> footerViewInfos, adapter);

venue_auto_complete.setAdapter(headeradapter);
