Android Question Pictures in the CustomListView

[johnerikson]

Is it possible to add pictures in the CustomListView class
In the Example of CustomListView class, there are no pictures (bitmaps)
If it possible, how?

Yes, you can add pictures. CLV is a very flexible object.
Just keep in mind that each CLV's item is a panel, so if you add an ImageView to your panel you'll see it when that panel is displayed (as part of the CLV).

An easy way to add elements to CLV's items is using the Designer to prepare a layout made up of all the items you want to show on a panel, then use that layout on the panel you add to the CLV. Different items could refer to different layouts.

Yed it's possible. Create a layout with an imageview then in the loop initialize the bitmap and it to imageview.

Thanks, it works
I add an Imageview in designer and change the code in the example like this

Sub CreateListItem(sImage As String, Text As String, Width As Int, Height As Int) As Panel
    Dim p As Panel
    p.Initialize("")
    p.SetLayout(0, 0, Width, Height)
    p.LoadLayout("CellItem")
    ImageView1.SetBackgroundImage(LoadBitmapResize(spathRot, sImage, ImageView1.Width, ImageView1.Height, True))
    Label1.Text = Text
    Return p
End Sub

Note that the latest version of CustomListView is xCustomListView. You should use it unless you are using an old version of B4A.

Example with images: https://www.b4x.com/android/forum/threads/cards-list-with-customlistview.87720/

If you are loading many images then you should add and remove items as explained here: [B4X] [XUI] CustomListView - lazy loading / virtualization

Thanks a lot!
It works. There seems to be no limit to possibilities, limitations is difficulties to find them!

After changing the method like the example https://www.b4x.com/android/forum/threads/87930 that appear to work
but Clv1_VisibleRangeChanged event not raised. By making a call to the event, I see the first cards.

What can I have missed?

I use:
Windows 10
jdk1.8.0_152
Android-27
B4A 7.80
Galaxy S8+

I´m going to try it!
