Hi Frank you can use this:

'Adds an ULV to the activity
ULV.Initialize(0, 0, "", "ULV")
ULV.Color = Colors.White
ULV.SelectionMode = ULV.SELECTION_SINGLE '<---- This is for select Single Row
Activity.AddView(ULV, 0, 0, 100%x, 100%y)
....


Sub Item_ContentFiller(ItemID As Long, LayoutName As String, LayoutPanel As Panel, Position As Int)
'Sets the text of the label
If ULV.IsSelected(Position) Then
'The selected rows are green
LayoutPanel.Color = Colors.Green '<---- This if you select row is GREEN
Else
'Alternatively, the rows are coloured in white or in light gray
If Position Mod 2 = 0 Then
LayoutPanel.Color = Colors.White
Else
LayoutPanel.Color = Colors.LightGray
End If
End If
.....

if Keycode = Keycodes..... then
i = i + 1
ULV.JumpTo(i,True) '<--- This is for jump in position that you want
ULV.SetSelected(i, True) '<--- This is for colour ( as you tap about row, Select row )
End If

    ULV.SelectionMode = ULV.SELECTION_SINGLE
    Activity.AddView(ULV, 0, 0, 100%x, 100%y)

    'Creates a layout to display the fruit name and builds the items list (1 item = 1 fruit)
    ULV.AddLayout("FRUIT_NAME", "Item_LayoutCreator", "Item_ContentFiller", ItemHeight, True)
    ULV.BulkAddItems(Fruits.Size, "FRUIT_NAME", 0)
  
    ULV.SetSelected(0, True)
