Presumably not, if your analysis is correct, and I suspect it is. To get the visual effect you want, use ListView and ExpandableListView as the contents of the tabs, not activities. Then, you can provide them with unique widget IDs. You will save memory, save CPU time, save battery life, reduce the odds that you will encounter a StackOverflowException for having too complicated of a UI, and solve this problem, all at the same time. -- Mark Murphy (a Commons Guy) http://commonsware.com Android App Developer Books: http://commonsware.com/books.html
