I don't think this works yet (a sub variable as the 'IN'). Try this (untested, I'm not at my PC):
Dim tmpList as List = myListView.Items
For Each myLVI As ListViewItem In tmpList
Log(myLVI.Text)
Next
For now, sometimes you will have to break the code a bit down to simpler objects I'm afraid. B4X wasn't build in a day either
The more BANano evolves, the closer I will get it to all B4J can do. This is a prime example of what I will look for in the next version of BANano.
