问题
My app is currently using the Fragments/v4 compatibility package to support Android versions all the way down to 1.6. This means all my Fragments inherit from the compatibility package's version of Fragment
. I'm currently trying to rework parts of the app to take advantage of Honeycomb features, like ActionBar
.
I already use my own action-bar-like implementation on pre-3.0 devices, and the Honeycomb Action Bar otherwise. This bit isn't an issue.
The problem I have is trying to implement tabs using the ActionBar. ActionBar.TabListener
expects the native Fragment
and FragmentTransaction
classes to work - so trying to use my Fragment classes (which inherit from the compatibility library) doesn't compile.
So, does anyone have any ideas how I can use fragments that use the compatibility package version of Fragment
with ActionBar
tabs?
tldr: how can I use ActionBar tabs with fragments that inherit from the v4 compatibility library?

I asked this question on the android-developers mailing list.
The approach I've taken is the one suggested by CommonsWare, whereby the provided FragmentTransaction parameter is ignored entirely: http://groups.google.com/group/android-developers/msg/d8d84cdd2f753b71
