Custom AdapterView with complex positioning of children

Question

I am trying to implement a custom AdapterView that draws it's child in own way following Making your own 3D list. What i am trying to do is draw the children in sort of a surface where they are positioned irregularly and are of irregular sizes. The children are selectable and the AdapterView otherwise Functions like a ListView. The reason i am using a AdapterView is because i want to populate it with a adapter which gets it's data from database. How do i draw the children in it's position and implement scrolling and selection? P.S. The Height of the "Surface" is Fixed and width is set to match_parent
