CustomListView - A flexible list based on ScrollView

About the divider line...

I don't get dividers when I add my custom item. So I opened the example and it seems to me that you get the divider (second CLV) by placing the views not on top (layout).
If you add a simple text item (AddTextItem) it seems that the dividerHeight is used.

Is it so?


[BTW in InsertAtTextItem there is a literal 2dip]

No, it isn't. You voluntary placed the views not in top but not to get the divider.

Anyway, I don't get it, creating the item in the same way you did.

Please start a new thread in the questions forum for the divider issue. Make sure to upload a project that demonstrates it (and uses the unmodified CustomListView class).

V1.76 was released. See first post for more information.

It seems to me that there is a bug.

To demonstate it, I'm attaching a small project (sizes are set for my tablet, in portrait mode, sorry ).

On Activity creation, I add 2 items; then, in the Button1 click event, I remove them and add 2 new items (identical).
Clickng several times you will see that the position of the new second item will be wrong.


P.S. Replaced the CLV with the new and original version 1.76 (same bug).

Note that you don't need this designer script line:

CustomListView1.SetTopAndBottom(0, Button1.Top - 4dip)

Just set the vertical anchors to BOTH.

The issue is fixed for the next update. It happens when you call RemoveAt and remove the last item. Change RemoveAt code to:

Public Sub RemoveAt(Index As Int)
   If GetSize <= 1 Then
     Clear
     Return
   End If
   Dim removePanel, p As Panel
   removePanel = panels.Get(Index)
   For i = Index + 1 To items.Size - 1
     p = panels.Get(i)
     p.Tag = i - 1
     Dim NewTop As Int = p.Top - heights.Get(Index) - dividerHeight
     p.top = NewTop
   Next
   sv.Panel.Height = sv.Panel.Height - heights.Get(Index) - dividerHeight
   items.RemoveAt(Index)
   panels.RemoveAt(Index)
   heights.RemoveAt(Index)
   removePanel.RemoveView
End Sub

Is it possible to identify a specific panel based on his own tag?

 

[Erel]

Everything is possible. Please start a new thread in the questions forum.

Can these be useful?

Public Sub GetItemFromValue(Value As Object) As Int
    Return items.IndexOf(Value)
End Sub

Public Sub GetPanelFromValue(Value As Object) As Panel
    Dim pnl As Panel
    Dim idx As Int = items.IndexOf(Value)
    If idx > - 1 Then
        pnl = panels.Get(idx)
    End If
    Return pnl
End Sub

If they are useful for you then add them.

1. You assume that all values are unique. This may not be the case.
2. CustomListView will not be updated any more. It is replaced with xCustomListView.

Are you sure?

Yes, but there may be some cases (user rankings).
Otherwise, the method (or a v.2) could return a list of panels.

2. CustomListView will not be updated any more. It is replaced with xCustomListView.

I had forgotten to have read this "new CLV"; I will add these posts to that thread (I'm kidding ).

How can i add group headers in the list view?

Thread is locked. You can start a new thread for any questions you have. Note that it is recommended to switch to xCustomListView.
xCustomListView is more powerful and is cross platform.
