Android Code Snippet Change Tab Stop on Labels and Listview using CSBuilder

As the title says. The method is based on span manipulation used in the thread below. If this is an existing solution, let me know, I couldn't find it.

Sub Activity_Create(FirstTime As Boolean)
    Dim lbl As Label
    lbl.Initialize("")
    lbl.Color = Colors.LightGray
    lbl.TextSize = 30
    Activity.addView(lbl, 10dip, 50dip, Activity.Width-20dip, 50dip)
    Dim cs As CSBuilder
    cs.Initialize
    cs.color(Colors.Blue).Append("here" & TAB & "there")
    Sleep(0)        'without this it doesn't work
    CallSub3(Me, "AddFirstTabStop", cs, Array As Int(350dip))
    lbl.Text = cs.PopAll
End Sub

Sub AddFirstTabStop(cs As Object, atStop() As Int)
    Dim span As JavaObject
    span.InitializeNewInstance("android.text.style.TabStopSpan.Standard", Array(atStop(0)))
    Dim jo As JavaObject = cs
    jo.RunMethod("open", Array(span))
End Sub

Note: I have tested it with Listview and it works, however if you change the backgroundColor of the item, the tab space color is not changed.
