iOS Question B4i - CustomListView - A line to separate items

[ciginfo]

I have to add a line between different items in a customlistview.
I thaught it was possible to modify Private HighlightColor in the customListView module (Private HighlightColor As Int = Colors.Black) but it does not change.
Can I modify "dividerHeight = 1dip" and how modify the color othe line which divide?
Thank you

I can change in CustomListView module
"dividerHeight = 5dip" 'sets dividers thickness
and
"sv.Color = Colors.Black" 'sets dividers Colors
And I obtain what I hope.
