Josh,
I have getViewTypeCount (2 here) & getItemViewType (0/text_row, 1/
icon_row) in my adapter so it knows about the two row types.
ConvertView is set to the correct row type.
The question is how correctly apply merge & remove
LinearLayout given:
* layout/icon_row.xml w/ <LinearLayout>/icon_row
* layout/icon_text.xml w/ <Linearlayout>/icon_text
If I simply replace <LinearLayout> with <merge> in above xml's,
inflate will throw exception w/o a ViewGroup parent.
So I need to pass in ViewGroup to my Adapter somehow.
Thanks.
