I noticed that Adapter object is not null, but the list is still showing “No records available to display. I think the issue has to do with the way that I am s

I have a very basic shell of a code I’m working on (for UI) before I dump in all my activities. A problems is that my device runs on 3.1 instead of 3.2 so I can’t just attach and detach my tabs. I’ve found this code called EffectiveNavigation from the Android SDK Samples (I think) and edited it to suit my code. Problem is, the navigational tabs only function when the Fragments called are Fragments, not when it’s a FragmentActivity or a ListFragment. I have no idea what’s happening and I hope tha

Short Background: Basically my group’s first android application that we are constructing for a Senior Design class at our University. It was essentially a navigation and user interface practice while implementing a database. The instructor plans to use the application in the future so we had to make it backwards compatible for android 2.3.xProblem: It would seem SherlockListFragment doesn’t implement a onListLongItemClick and it has a mind of its own inside the code. It disallows me to override
