It's not quite what I want (expandable list). I want two different and independent lists, side by side. – user1705941 Sep 28 '12 at 10:47
ok, but would have to build the tree recursively and dynamic with various levels – user1705941 Sep 28 '12 at 11:00

you can create two Listview and put them side by side. 1st list will contains 1,2,3,4...n and when you click on any number for e.g. you clicked on 2 then 2.1,2.2,2.3....2.n will appear on 2nd list.

This might help you to understand how ListView is working in Android http://www.vogella.com/articles/AndroidListView/article.html

Second list is a submenu of first list. I hope you noticed – user1705941 Sep 28 '12 at 11:16
yes I can notice it, so what is the issue you are facing when you create two ListViews and put them side by side? – kaushal Sep 28 '12 at 11:24
recursively when i clicked in the second list must appear a third and so on – user1705941 Sep 28 '12 at 11:30
If you know how to add/remove ListView at run time then you can achieve this – kaushal Sep 28 '12 at 11:56
