You are looking for ExpandableListView, which allows you to have two levels of expansion. Listview (which is what is used in the NotePad example) only allows one level.

I haven't started working with those yet, so I can't recommend any specific tutorials or examples, but now that you know the name of what you are looking for, poke around the android dev site and google about. The first search hit is here if it's worth anything.

Good luck!

I would spend some time going through the sample code and references on d.android.com

Have a look at ListView and the Notepad example project http://d.android.com/resources/samples/NotePad/index.html
