iOS Question Dynamic ScrollView creation

[jazzzzzzz]

Am porting one of my b4a app to b4i. Am attaching a scroll view initializing part ,this "initialiseView" sub is called when ever a pull refresh happens in scroll view. when refresh occur I dynamically remove current scroll panel contents and then adds all views from beginning (So that new data from my server will added to the scroll view) coding is working well but as this is not in Page_resize %x and %y values cannot be assured and after all refreshes the view goes small inside the scroll view.

Suggest a way to dynamically create this type of scroll view with contents with page_resize usage and all.

Sub initialiseView
   
    If dashScroll.IsInitialized = False Then
        dashboard.RootPanel.Color = Colors.LightGray
        dashScroll.Initialize("dashScroll",100%x,45%y*currentContests.Size-1)
        dashboard.RootPanel.AddView(dashScroll,0,0,100%x,100%y)   
        AddRefresh(dashScroll)
        downlaoder.Initialize
        Log("first"&45%y&"  width"&dashboard.RootPanel.Height)
    Else

        dashScroll.Panel.RemoveAllViews
        dashScroll.ContentHeight = 45%y*currentContests.Size-1
        dashScroll.ContentWidth = 100%x
        Log("secon"&45%y&"  width"&dashboard.RootPanel.Height)
    End If
   
    For i=0 To currentContests.Size-1
       
        Dim p As Panel
        Dim iv As ImageView
        Dim heading As Label
        Dim description As Label
        Dim photoNum As Label
        Dim photoNumIcon As ImageView
        Dim headingShadow As ImageView
        Dim uploadPicIcon As ImageView
       
        Dim m As Map
        m=currentContests.Get(i)
       
        p.Initialize("panel")
        heading.Initialize("")
        description.Initialize("")
        photoNum.Initialize("")
        photoNumIcon.Initialize("")
        headingShadow.Initialize("")
        uploadPicIcon.Initialize("uploadPicIcon")
       
        p.Color=Colors.White
        iv.Initialize("")
        Main.downloadLinks.Put(iv,m.Get("cover_photo"))

       
        heading.Text = m.Get("contest_name")
        heading.Text = heading.Text.ToUpperCase
        heading.TextColor=Colors.White   
       
        description.Text = m.Get("description")
        description.TextColor=Colors.White

        photoNum.Text = m.Get("photo_count")
        photoNum.TextColor=Colors.White
       
        photoNumIcon.Bitmap = LoadBitmap(File.DirAssets,"image_holder.png")
        headingShadow.Bitmap =    LoadBitmap(File.DirAssets,"shadow.png")
        uploadPicIcon.Bitmap =    LoadBitmap(File.DirAssets,"picture-add.png")
       
        p.AddView(iv,0,0,100%x,45%y)
        p.AddView(headingShadow,0,33%y,100%x,12%y)
        p.AddView(heading,2%x,34%y,100%x,10%y)
        p.AddView(description,2%x,40%y,100%x,4%y)
        p.AddView(photoNum,10%x,3%y,10%x,5%y)
        p.AddView(photoNumIcon,2%x,2%y,8%x,8%x)
        p.AddView(uploadPicIcon,85%x,2%y,13%x,11%x)
       
        uploadPicIcon.Tag=i
        p.Tag=i
        dashScroll.Panel.AddView(p,0,i*45%y,100%x,45%y)   
    Next
    downlaoder.Download(Main.downloadLinks)
End Sub

Log("first"&45%y&"  width"&dashboard.RootPanel.Height)

this 45%y gives wierd outputs on all refreshes as its not in Page_Resize.
Please suggest a way to structure it for b4i

1. Don't load the same bitmaps multiple times. Load them once before the first loop.

2. Use dashboard.RootPanel.Width and dashboard.RootPanel.Height outside of the Resize event.

3. Handle the resize event and adjust the scrollview based on the updated page size.

I recommend you to use CustomListView. It will make your code simpler.
