I'm not seeing any evidence why getViewTypeCount() or getItemViewType() would be needed. Based on the description, the items views appear to be homogeneous.
It looks weird to me that "public void refreshView" does not take an "int position" parameter. How does it know that it needs to set the views with the data for the "position"'th item? And that's probably what the issue is - the original MyItemView created for item A is reused for item F, and B for G, so it updates the views with the wrong data. Another point - it's not necessary to call invalidate() like you're doing. -- K 2012/7/27 Justin Anderson <magouyaw...@gmail.com> > Look at and implement these methods: > > > http://developer.android.com/reference/android/widget/Adapter.html#getItemViewType(int) > > http://developer.android.com/reference/android/widget/Adapter.html#getViewTypeCount() > > Thanks, > Justin Anderson > MagouyaWare Developer > http://sites.google.com/site/magouyaware > > > > On Thu, Jul 26, 2012 at 4:59 AM, Sergio Panico <sergio.pan...@gmail.com>wrote: > >> Hi all, >> I need your help to understand the refresh behaviour of a ListView where >> I've defined a my custom view for the ListView's items. >> >> I think It's better explain it with an example: >> my adapter contains 7 items: A, B, C, D, E, F, G correctly initialized, >> filled and working.
