Answer 1

I have tried the responses listed but i found that i can use the getGroupCount() method to get the number of groups.

Using this method i can iterate and expand every group of my ExpandableListView

for (int i = 0; i < myExpandableListView.getExpandableListAdapter().getGroupCount(); i++) {
      //Expand group
      myExpandableListView.expandGroup(i);
 }
