Android Question Panel.LoadLayout Error

[Guenter Becker]

Whish you a happy christmas,

I am developing a customcontrol. I like to use a panel and load a layout build with the designer into it and than add the panel to the base of the custom control:

    mprops = Props
    Panel.Width = mBase.Width:Panel.Height=mBase.height
    Panel.LoadLayout("ActionBarPanel")
    mBase.AddView(Panel,0,0,mBase.Width,mBase.Height)

    mprops = Props
    Panel.Width = mBase.Width:Panel.Height=mBase.height
    mBase.AddView(Panel,0,0,mBase.Width,mBase.Height)
    Panel.LoadLayout("ActionBarPanel")

The layout only contains a panel with some child views a label and an imageview.

If I use the customcontrol on a layout loaded into an activity and run the app I get the error as follows:

*** Service (starter) Create ***
** Service (starter) Start **
** Activity (main) Create, isFirst = true **
Error occurred on line: 68 (extActionBar)

Thank you, following the information I solved it:

Sub Activity_Create(FirstTime As Boolean)
    Activity.LoadLayout("Test") 'Load Layout with custom control and jump to Activity_Resume
    CallSubDelayed(Me, "Initialization2")
    'Wait that custom controll is full initialized and jump to initialize2'
End Sub

Sub Activity_Resume
' jump back to Activit_Create and CallSubDelayed
End Sub

Sub Activity_Pause (UserClosed As Boolean)

End Sub

#region --- Initialization ---
Sub Initialization2
    ' now ist able to work tith the custom control
    extActionBar1.MainTitle.text = "Test"
End Sub
