Hi Romain, Thanks for your response, though I had a couple of questions for you;
1) None of the LinearLayout's contain the layout_wieght attribute...So I'm not sure that's my problem. 2) Could you please breifly explain the logic behind why the framework requires n passes over the ListViws items? 3) Give that this is an overhead, can you suggest an approach that does not suffer this?
