B4J Question [solved] xCustomListView not showing webview

[Lahksman]

Hi all

I'm trying to load a webview inside a customlistview but all i'm getting is a blank listview with the currect number of items.


This is the code I'm using to fill the customlistview

Sub btnSetOphalen_Click
    Dim setNummer As String = txtSetNummer.Text & "-1"
    objSet.Initialize
    Wait For(Rebrickable_API.DownloadSets(setNummer,Auth_key)) Complete (Result As Boolean)
    Wait For(Rebrickable_API.DownloadTheme(objSet.SetThemaId,Auth_key)) Complete (Result As Boolean)
    Wait For(Rebrickable_API.DownloadParts(objSet.SetNumber,Auth_key)) Complete (arParts As List)
    If Not(objSet.SetHoofdThemaId = "-1") Then
        Wait For(Rebrickable_API.DownloadParentTheme(objSet.SetHoofdThemaId,Auth_key)) Complete (Result As Boolean)
    End If
    wvSetAfbeelding.LoadUrl(objSet.SetAfbeelding)
    lblSetAantalStukken.Text = objSet.SetAantalStukken
    lblSetNaam.Text = objSet.SetNaam
    lblSetNummer.Text = objSet.SetNumber
   
    Log("# of parts: " & arParts.Size)
    xlvSetOnderdelen.Clear
    For Each v_part In arParts      
        Dim objPart As Part = v_part
        xlvSetOnderdelen.Add(CreateItem(objPart),"")
    Next
    Log("listview size: " & xlvSetOnderdelen.Size)
End Sub

Private Sub CreateItem (v_objPart As Part) As B4XView
    Dim p As B4XView = xui.CreatePanel("")
    p.SetLayoutAnimated(0,0,0,100,100)
    p.LoadLayout("ItemLayout")
    Log(v_objPart.PartAfbeelding)
    wvPartAfbeelding.LoadUrl(v_objPart.PartAfbeelding)
    Return p
End Sub

As you can see in the log, all items are created but nothing is showing.

# of parts: 11

Using WebView to show an image is most probably a mistake.

Are you sure that the WebView in ItemLayout is named wvPartAfbeelding?

 

[Lahksman]

I'm using a webview to avoid having to download all the pictures, this set only has 11 parts, but there are also sets with several hundreds of parts.
If someone has a better way of doing this, please say so.

I've double checked name and it's indeed wvPartAfbeelding, generated the member from the layout designer.

You cannot show an image without downloading. You are letting WebView do it for you. That's reasonable.

Try to reproduce it in a small project and upload it.

I tried to reproduce it in a small project but there it works as intended.

I've succesfully implemented bitmapasync, thx for the info.
