I found a solution using a reflector to get X coordinate combined with CustomListView_ItemClick.
If X > screen.width /2 then user clicked the second item.
I guess there was probably a cleaner method...
B4X:
Dim r As Reflector
r.Target = p
r.SetOnTouchListener("scvTest_Touch")
(...)
Sub scvTest_Touch(viewtag As Object, action As Int, X As Float, Y As Float, motionevent As Object) As Boolean
Log(x)
End Sub
