There are literally so many examples for your requirement!

Anyway, you might want to look into this blog, if you already haven't.

"does it mean that I have to create two layout for the group and the child view?"

OF course, yes! , I mean you can choose to not create layouts, but then again it's your choice and this has very less to do with ExpandableList

The GroupList ideally would contain a list of Teams line List = {"Development Team", "Data Process Team"} (This will predominantly used for display purpose only like calculating the height of the list etc.)

The ChildList ideally would contain a list of lists (Hashmap of Lists rather)

Hashmap> =

Development Team: List = {"John", "Bill"} Data Process Team: List = {"John", "Bill"}
