Android Question Custom Listview methods not working after being populated

[elitse]

I populated a customlistview from a JSON file. I added a button which was supposed to clear the custom list view and add new items, but this is not happening.

    ' this part works'
    MenuItems = map1.Get("bulletins")
    For i = 0 To MenuItems.Size - 1
        m = MenuItems.Get(i)
        If m.Get("callSign")="ALL" And m.Get("aircraftType")=actype Then
            lstbulletin.AddTextItem(m.Get("summary"),i)
            
        End If
            
    Next
    

Private Sub Button1_Click
    'this is not working'
    lstbulletin.Clear
    lstbulletin.AddTextItem("hi",100)
    
End Sub

Are you using B4XPages? Are you loading the layout once?

Such problems are usually related to layouts being loaded multiple times by mistake.

Hi Erel. Thanks for the quick reply. You were right

'TabStrip1.LoadLayout("MainPage", "Bulletins")

I had this code at the beginning. Does this mean we can't add the main page to a tabstrip view?

You are not giving us enough information...

Private Sub B4XPage_Created (Root1 As B4XView)
    Root = Root1
    Root.LoadLayout("MainPage")
    B4XPages.GetManager.SetTitle(Me,"Boeing Bulletins")
    Initialize_bulletin
    
    [B]'TabStrip1.LoadLayout("MainPage", "Bulletins")[/B]
    'TabStrip1.LoadLayout("details", "Details")
    
    
    
    
End Sub

When I commented out code in bold above, problem was resolved. Thanks. I
