I don't know if I asked correctly? I would like to run CLV in activity. I don't know what I'm doing wrong, I still have this error.
B4X:

I prepared a small project that shows the problem. The data are loaded from the database in the original.

I used both libraries. CustomListView (1.76) and xCustomListView (1.70).
