Can you upload listitem.bal?
Greate Thanks a lot.The error happened because the "activity" color is a gradient color.
It shouldn't have crashed. You've hit a bug in XUI library that caused this crash. It is fixed for the next update.
You should set the background color to a solid color (or the default color). If you like to have an item with a gradient color then add a panel and set its background (with the designer).
Thanks.Note that you should still use a solid color. B4XView.Color will just not crash and return a transparent color instead.
