Hi
If I understand correctly, you want to put data in a listview.
Listview is not a good solution. Use xCustomListView

[B4X] [XUI] xCustomListView - cross platform CustomListView

Update: As several other libraries depend on xCustomListView library, it is no longer recommended to use the code module. Use the library instead. There are several extension classes that add more features to xCLV. They are listed at the end of this post. Video tutorial: xCustomListView is...

A little more detail would help for better help.

There are parameters that have not been defined. It can't work
Can you post a project to clearly see what is wrong

You can always add CLV. You are doing something wrong.

here is an example. A small part of the project cannot be added. If it doesn't work out, I'll throw the project to you

it just can't be added to the AH Page Container if you know the code, please write

 

[Andrew (Digitwell)]

A way to do this is to add the customlistview to a layout. Load the layout into a panel and then add the panel to the PageContainer.
CustomListViews were not designed to be added outside a layout.

        Case TYPE_SETTINGS
            CustomListView1.Initialize("","")
            pan.AddView(CustomListView1.AsView, 0, 0, 100%x, 100%y)
    
    
    Should be:
    
    Case TYPE_SETTINGS
        private p as b4xview = xui.createpanel("p")
        p.setLayoutAnimated(0,0,0,100%x,100%y)
        p.loadlayout("LayoutwithCLVonly") ' Make sure you set the anchors to cover the complete page
        pan.addview(p,0,0,100%x,100%y)
