Android Question How can I add a new event in xCustomListView?

Like this

Sub CreateListItem(Text As String, Width As Int, Height As Int) As Panel
    Dim p As Panel
    p.Initialize("Panel") '<---I add the eventname Panel here
    p.SetLayout(0, 0, Width, Height)
    p.LoadLayout("CellItem")
    Label1.Text = Text
    Return p
End Sub

Sub clv_ItemLongClick (Index As Int, Value As Object)
   log("You pressed the Long click")
End Sub

Private Sub PanelLongClickHandler(SenderPanel As B4XView)
    Dim clr As Int = clv.GetRawListItem(SenderPanel.Tag).Panel.Color
    Dim PressedColor As Int = 0xFF7EB4FA
    Dim EventName As String = "clv"
    SenderPanel.SetColorAnimated(50, clr, PressedColor)
    If xui.SubExists(Me, EventName & "_ItemLongClick", 2) Then
        CallSub3(Me, EventName & "_ItemLongClick", SenderPanel.Tag, clv.GetRawListItem(SenderPanel.Tag).Value)
    End If
    Sleep(200)
    SenderPanel.SetColorAnimated(200, PressedColor, clr)
End Sub

#If B4A
Private Sub Panel_LongClick
    PanelLongClickHandler(clv.GetRawListItem(clv.GetItemFromView(Sender)).Panel)
End Sub
#Else If B4i
    Private Sub Panel_LongClick
        PanelLongClickHandler(Sender)
    End Sub
#Else If B4J
'    Private Sub Panel_MouseLongClicked (EventData As MouseEvent)
'        PanelLongClickHandler(Sender)
'    End Sub
#End If
