I recently converted my application from using Activites and TabHost to using Fragments and ViewPager using the Android Compat Library for API v4 I was able to fix/resolve most problems but am unable to retain the previous behavior with filtering text in ListViews using the setTextFilterEnabled<http://developer.android.com/reference/android/widget/AbsListView.html#setTextFilterEnabled(boolean)> method.
My ViewPagerAdapter contains Fragments which each have a ListView. As users swipe through the ViewPager, I would like the currently active Fragment's ListView to filter text as users type, just like I was able to do with the TabHost-Activity model. Currently, it looks like the first Fragment's ListView will respond correctly, but if I swipe to the next Fragment and try to filter its ListView, the filtering will still apply to the first one. If I swipe past the first two and then filter, the results are non deterministic. The currently active Fragment will never apply the filter. Sometimes a neighboring fragment will, sometimes it won't. I tried to fix this by adding custom callbacks which let me monitor which Fragment is currently visible, and which are hidden. When a fragment becomes visible as the main Fragment of the ViewPager, I set the setTextFilterEnabled on its ListView to 'true', and set all others to 'false'. This didn't seem to help at all (I verified that I was toggling the flag correctly for the right Fragments). I suspect this needs some kind of deeper integration with ViewPager, but I can't really figure out what I need to wire up. Any ideas on how I can make this work? I'm happy to much with the ACL code if needed. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
