Android Question ScrollView not scrolling

[GiovanniPolese]

Hi to Everybody
I have a strange situation, using a ScrollView. The following code worked in the past. Now I am trying to re-use it and the scrollview that I used, doesn't scroll automatically. The ScrollView is named "Lista" and is defined in the designer (with internal height 500, the default). The sub assumes a global iRow counter that is sequentially incremented by other operations.

Sub AddLineToList
    
    Dim Row As Panel
    Dim pos As Int
    Dim RowHeight,nRowPage As Int
   
    RowHeight=26dip

    nRowPage=Lista.Height/RowHeight

    Row.Initialize("")
    '.....
    ' Row is filled by other Views that I omit to avoid confusion
    ' then Row is added to the Lista.Panel at iRow-1 position

    Lista.Panel.AddView(Row,1,2dip+(iRow-1)*(RowHeight) ,Lista.Width-6,RowHeight)
    
    pos=RowHeight*(iRow-nRowPage+1)

    If pos>0 Then
        Lista.ScrollPosition=pos ' doesn't work ... nothing happens .
    End If
End Sub

In my case, I have 23 nRow. Initially pos is negative, but also when it becomes positive (adding rows, incrementing iRow), the ScrollView doesn't scroll up...BUT, as I said, such code worked in other Apps and I don't figure out what is now happening or what I am missing..
Thanks in advance for any hint.

I posted quite some time ago this Scrollview examples summary, the examples are old, but the principles remain the same.
There does exist the Flexible Table Class, but this one is a monster.

Usually I don't need monsters. Your summary is rather complete for normal needs. Thanks again.
