This might give you an Idea ... The code below has not been tested !

adaption of this code here .. https://www.b4x.com/android/forum/threads/b4x-okhttputils2-with-wait-For.79345/#content
... and using the xCustomListview example.

B4X:

Sub DownloadImage(Link As String)
    Dim j As HttpJob
    j.Initialize("", Me)
    j.Download(Link)
    Wait For (j) JobDone(j As HttpJob)
    If j.Success Then
        clv.Add(CreateListItem(j.GetBitmap, clv.AsView.Width, 130dip), "MyReturnValue")
    End If
    j.Release
End Sub

Sub CreateListItem(bmp As Bitmap, Width As Int, Height As Int) As Panel
    Dim p As B4XView = xui.CreatePanel("")
    p.SetLayoutAnimated(0, 0, 0, Width, Height)
    p.LoadLayout("CellItem")
    ImageView1.Bitmap = bmp
    Return p
End Sub

Edit ... I presume you have an ImageView (ImageView1) included in your CLV RowItems layout.
