Android Question Remove customlistview item

[omidaghakhani1368]

Hi
I add 10 item to customlistview example below

1: for i = 0 to 10
   2: dim p1 as panel
   3: p1.initialize("")
   4: customlistview1.add(p1,100,i)
   5: p1.loadlayout("frm1")
6: next

when i remove item from 10 items,and again remove item then get error that not exist index
i use index from line 4 variable i

I save index of each panel in button tag
when i click on button i get button tag (it is index) and then remove item with index
but after remove item,count of item in list minus 1 and not exist index
how i load all views?your meaning is load all item again?

You don't need to handle the index of items (at least, not in this case).
You should use the same method you can see in the example project
(you should use the names of your views instead of Button and clv3, of course):

Sub Button_Click
    Dim index As Int
    index = clv3.GetItemFromView(Sender)

'    Dim pnl As Panel
'    pnl = clv3.GetPanel(index)
 
'    Dim lbl As Label
'    Dim chk As CheckBox
'    lbl = pnl.GetView(0)
'    chk = pnl.GetView(2)
'    lbl.Text = "Clicked!"
'    Msgbox("Item value: " & clv3.GetValue(index) & CRLF & "Check value: " & chk.Checked, "")
  
     ' This if you want remove the Item
     clv3.RemoveAt(index)
End Sub

It returns the Item index (that is related to the panel, of course, but you should work on / with Items)

In his code he is asking the index of the SENDER (the view that raised that event) and in this case its the button
