Android Question [Solved] Error removing title in [B4X] B4XPages + B4XDrawer example

[AnandGupta]

I want to make my own custom title bar (with icons, text, color etc.) and I need to have drawer.
I have already done it in multi activity logic. Now trying same in B4XPages.

I found

B4XPages - hide title bar?

This new feature is great and should help advance cross platform development with b4x even further. In looking it over, I was wondering if there is a way to hide the title bar?

and

[ B4X Pages ] How can i alignt center title text ?

hello everyone !! i am trying to align title bar text to center horizontally , but dont works ... :c code : Dim cs As CSBuilder cs.Initialize.Alignment("ALIGN_CENTER").Append("Menu Saúde").PopAll B4XPages.SetTitle(Me,cs)

www.b4x.com

So I removed title from B4XPages example "[B4X] B4XPages + B4XDrawer" example

[B4X] B4XPages + B4XDrawer

B4XDrawer v1.53 adds support for B4J. This is a good opportunity to create a B4XPages example using B4XDrawer. It does require some configuration so pay attention. The example is based on the three pages example...

But it is giving error,

Can you post the code in B4XPage2.B4XPage_Appear ?

 

[AnandGupta]

Can you post the code in B4XPage2.B4XPage_Appear ?

Yes.

Private Sub B4XPage_Appear
    lblHello.Text = $"Hello ${B4XPages.MainPage.txtUser.Text}!"$
    UpdateImage
    #if B4A
    Sleep(0)
    B4XPages.GetManager.ActionBar.RunMethod("setDisplayHomeAsUpEnabled", Array(True))
    Dim bd As BitmapDrawable
    bd.Initialize(HamburgerIcon)
    B4XPages.GetManager.ActionBar.RunMethod("setHomeAsUpIndicator", Array(bd))
    #End If
End Sub

Remove the code that gets the action bar as there is no action bar.
