Android Question xcustomelistview set specific item visibility

[Addo]

i am creating items like following

Sub CreateListItem(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")
   label1.Text = " Name "
   labelnumber.Text = "100 "
   Return p
End Sub

i am trying to set some items visible to False how can i do that programmatically based on items index ?

I guess you want to hide an item reducing its height to zero.

You should use:

P.S. no, it is not enough, you should modify it as you should with xCustomListView.

i tried

xclv.GetPanel(1).Visible = False

with

xclv.AddTextItem("item1", "item1")
xclv.AddTextItem("item2", "item2")

the text hidden but the item itself still visible

It's not so easy; I have to do other things now, but the way is to create a HideItem routine, based on RemoveAt (copying RemoveAt and modifiyng its code)

The expandable version is not relevant here.

You can call RemoveAt to remove an item and later add it back with InsertAt.

You can call RemoveAt to remove an item and later add it back with InsertAt.

This the "most quick way", of course (you have to store the item and its index, in a "List of type tXXXItem).

A better solution would be to add a method like SetItemVisibility(Visible As Boolean).

The tag property is already used; maybe we can create an internal type, to store the Index and Visible.
Then the ItemVisibility routine should be very similar to RemovaAt.

I know, it's a "lot" of work.

New thread? Please, no

Property (at least read-only) for DividerSize.
