I'm referring to the view itself.

view.left = 50%x - view.width/2
view.top = 50%y - view.height/2

'display the view at the center of screen

Dim v As View
...
' find the center coordinates:
Dim cx,cy As Int
cx = v.Left + v.Width/2
cy = v.Top + v.Height

' or
' put the view there:
v.Left = cx - v.Width/2
v.Top = cy - v.Height/2

Sub SetHorizontalCenter(v As View,HorizontalCenter As Float)
    v.Left = HorizontalCenter - (v.Width/2)
End Sub

Sub SetVerticalCenter(v As View,VerticalCenter As Float)
    v.Top = VerticalCenter + (v.Height/2)
