Well you better post some code to get the right advice on your issue but based on the text inside your question I can suggest these steps,

  • setOnGroupExpandListener(new OnGroupExpandListener(){..}); on your expandable listview.

You will get onGroupExpand method where you will write your logic to refresh or do whatever you need to do in background in an Asynctask obviously.

  • Once you are done with the background work then inside onPostExecute() of your Asynctask set the adapter again or just call notifydatasetchanged if you have modified the data a bit.
