Android Question Scroll View -- My label to add is null?

[Torby]

This is my first post here. Do you have code tags?

Trying to make a scrollview's items vary in height according to the text size., so inside my loop, I have:

TopOfLine = y
Dim l As Label
l.Initialize("")
l.Gravity = Gravity.Left
l.TextSize = 32
l.TextColor = Colors.White
A = s.IndexOf2("|",0)
A = s.IndexOf2("|",A+1)
B = s.IndexOf2("|",A+1)
n = i+1
l.Width = w  ' *********** blows up here! ***********************
l.Text = n & ". " & s.SubString2(A+1,B)
l.Height = su.MeasureMultilineTextHeight(l, l.Text)
svOrder.Panel.Height = svOrder.Panel.Height + l.Height
LabelList.Add(l)
svOrder.Panel.AddView(l,5,y,svOrder.Width-5,l.Height)
y = y + l.Height

And above,

Dim w As Int = svList.Width
Dim y As Int = 0

However, it blows up when I try to set l.Width claiming a null pointer reference. It's already set l.TextSize and l.TextColor and l.Gravity.

Perhaps I should use another label for sizing the text, and not the one I just dimmed?

Dimly yours,

p.s. Oh, you do have code tags. And they are most beautiful.

To modify the Width or Height, you have to add the view to an activity or panel, in this case, to the ScrollView's panel.

So add it first, then adjust it.

Thanks.

And now it shows just like I wanted. Thanks.

I recommend you to use CustomListView class. clv.AddTextItem will automatically set the height based on the text length.
