Android Question MaterialDateTimePicker - How to use "HighlightedDays"

[jtare]

I'm trying to use the property "HighlightedDays()() As Calendar" but I can't make it work, I'm not sure how to.

I tried

        Dim cal As Calendar
        cal.Initialize("MMM dd, yyyy",cal.US,DateTime.Date(DateTime.Now))
        date.HighlightedDays = Array(cal)

        Dim cal As Calendar
        cal.Initialize("MMM dd, yyyy",cal.US,DateTime.Date(DateTime.Now))
        date.HighlightedDays = Array As Calendar(cal)

And many others... Does someone the right way to use this property? Thanks
