Answer 1

If you're talking about the arrow that is used to collapse/expand the list then you can remove it by using setGroupIndicator()

in the activity you can call

getExpandableListView().setGroupIndicator(null);

that will remove the arrow permanently though. If you want to only hide it if the list is empty you can do it through xml attributes like this

To launch an activity when the list is expanded/collapsed you can override onGroupExpanded (or collapsed) in your ListAdapter implementation and used that to fire up your activity
