That happen if you set view anchor to both in designer. So you will not be able get the width of that view in code

i have the error also if set item_privacy as empty layout and remove autoscale

Never load a layout to a zero sized panel.
Correct code:

Sub CreateListPrivacy(Width As Int) As Panel
Dim p As Panel
 
    p.Initialize("")
p.SetLayout(0, 0, 100%x, 40dip) '<--- set the size before loading the layout
    p.LoadLayout("privacy_item")
   
    Return p
End Sub

i have moved SetLayout because the item Height setted to 80dip, with android 9 sometimes, is too small

i have replace with the height of panel inside the layout (PanelDate.Height)

how to set the height correctly?

 

[Erel]

There is no such thing. You need to set the height as you need it.

if i set the anchor to expand and height=80dip the border down is out of layout

This layout is incorrect:

The distance from the bottom edge is set to 350dip. You have several options to fix it. The simplest one is to anchor the top panel to the top instead of BOTH.
I also recommend you to remove the AutoScaleAll call for these items as the variant size is different than the real size.
