Description

Problem : all list items take up the size of the first item in the adapter list - this is a terrible assumption for a generic library like this one!

My adapter has a header of toolbar height ?android:attr/actionBarSize and then a list variable length images - something like facebook's newsfeed. I ended up with a vertical stack of lots of items, all of the same toolbar height.

Is ther an easy fix to this? I haven't gone through the code yet, hence not aware of how much effort this would require.

Contributor guide
