Android Question Panel.Height: Release -> Ok, Debug -> not ok

[KMatle]

In a lot of my apps I use a Scrollview and put views dynamically on it. Today I've found a strange behaviour (B4A 4.30). Maybe I'm blind, but...

In release mode the panel's height is adjusted correctly (tested on 2 devices), in debug (both modes), it will not change (stays at 1000dip). Any ideas?

CMSsv.Initialize2(1000dip,"CMSsv") 
Activity.AddView(CMSsv,0,0,100%x,100%y)

later

toppos=1%y
        For i = eArtikel To lArtikel
           
            Artikel=ArtikelListe.get(i)
            filen=Artikel.Get("ImageFile")
         
            Dim ueb As Label
            ueb.Initialize("")
            ueb.Text=Artikel.Get("Ueberschrift")
            ueb.Gravity=Gravity.CENTER
            ueb.Color=Colors.DarkGray
            ueb.TextColor=Colors.ARGB(255,255,165,0)
            CMSsv.Panel.AddView(ueb,5%x,toppos,90%x,5%y)
            SetLabelTextSize(ueb,ueb.Text)
           
            toppos=toppos+5%y
            Dim ueb2 As Label
            ueb2.Initialize("")
            ueb2.Text=Artikel.Get("OnlineAb") & "  " & i & " (" & Artikel.Get("Autor") &")"
            ueb2.Gravity=Gravity.left
            ueb2.Color=Colors.DarkGray
            ueb2.TextColor=Colors.ARGB(255,255,165,0)
            CMSsv.Panel.AddView(ueb2,5%x,toppos,90%x,3%y)
            SetLabelTextSize(ueb2,ueb2.Text)
           
            toppos=toppos+4%y
            Dim im As ImageView
            im.Initialize("")
            im.Bitmap=LoadBitmap(mypath ,filen)
            im.Gravity=Gravity.CENTER
            CMSsv.Panel.AddView(im,5%x,toppos,44%x,30%y)
            Log(im.Width)
            Log(im.height)
           
            Dim te As Label
            te.Initialize("")
            te.Text=Artikel.Get("AText")
            te.Color=Colors.DarkGray
            te.TextColor=Colors.ARGB(255,255,165,0)
            CMSsv.Panel.AddView(te,50%x,toppos,45%x,30%y)
            SetLabelTextSize(te,te.Text)
                   
            toppos=toppos+32%y
       
        Next
        CMSsv.Panel.Height=toppos

working normally on both release and debug

Try to call requestLayout as done in this post: https://www.b4x.com/android/forum/t...r-panel-height-is-adjusted.49033/#post-305642

 

[KMatle]

The reason for this behaviour is setting a breakpoint. I can reproduce it.

      toppos=toppos+32%y
       
        Next
        
--->>>>>   CMSsv.Panel.Height=toppos
   
   
        Log("Panel height: " &CMSsv.Panel.Height)
        Log("CMSSV height: " &CMSsv.Height)

Setting it to "CMSsv.Panel.Height=toppos" seems to skip the line -> heigth not set

So it's clear why it works in Release and not in Debug.

@Erel : Is is a bug?

 

[Erel]

Have you tried to call requestLayout?

 

[KMatle]

Yes. It works (but adding code for debugging is not that comfortable)

Without the code:

-> Release: Everything is fine
-> Debug + with breakpoint at the same line which adjusts the height: Doesn't work
-> Debug + no breakpoint at the same line which adjusts the height: Everything is fine

Does the debugger prevent it?

Easiest solution: No breakpoint at the line which adjusts the panel's height.

Confusius once said... "if you know where the troubles are... why not just avoid them"?

Well... maybe it was not confusius ...

 

[Erel]

Does the debugger prevent it?

Seems like the message handling done by the debugger prevents the ScrollView from updating the height. However calling requestLayout may be needed in release mode as well (see the discussion in that link).
