I do not think your approach will be very user-friendly, particularly on smaller screens. Why are you forcing all of this into a single ListView? Why not: -- A ListView above and a single TableLayout (perhaps in a ScrollView) below, where the TableLayout's contents change based upon clicks in the ListView -- A ListView in one activity and the details (in a TableLayout or whatever) in a second activity, started by clicking on a ListView row in the first activity? -- Mark Murphy (a Commons Guy) http://commonsware.com | http://github.com/commonsguy http://commonsware.com/blog | http://twitter.com/commonsguy Android Training in London: http://skillsmatter.com/go/os-mobile-server -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
