Check underneath the break room table -- it might be propping up a short leg.

Let's say that for large-screen devices you want 3 fragments in portrait and 5 in landscape. The same 3 are in both; landscape adds two more. In portrait, you'd use three <fragment> elements. In landscape, you'd also use three <fragment> elements, plus a pair of <FrameLayout> elements. Those latter two are the placeholders for where dynamic fragments will go. (technically they don't have to be FrameLayouts, but could be something else -- I've been delegating the positioning to other layouts and simply using FrameLayout as the "slot" to drop in a Fragment via a FragmentTransaction) So, you use the declarative layouts for all of the sizing and positioning and stuff, but you only declare the fixed fragments' contents declaratively, and the dynamic fragments' contents dynamically. Another approach, that I show in my introductory book, would have the same five <fragment> elements in both portrait *and* landscape, and you just make the Views for the extra two be View.GONE in portrait mode. This works, and avoids the FragmentTransactions, but it feels a bit clunky to me. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://github.com/commonsguy http://commonsware.com/blog | http://twitter.com/commonsguy Android Training...At Your Office: http://commonsware.com/training -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
