Android Question looking for Library

[MikeFree]

what kind of library has to be linked using following code :
(nav as NavigationController)

 

[mangojack]

That code / declaration seems more associated witha B4i app / project

Private Sub Application_Start (Nav As NavigationController)

Is it definitely a B4A app your working on ? What are you trying to do ?

Maybe post a few extra lines of code following this.
[code] paste / place your code between code tags ... [/code]

 

[MikeFree]

compiler stuck at this line:
Private Sub Application_Start (Nav As NavigationController) ...

'Button create at runtime

Private Sub Application_Start (Nav As NavigationController)
    NavControl = Nav
    Page1.Initialize("Page1")
    Page1.RootPanel.LoadLayout("1")
    NavControl.ShowPage(Page1)
    Page1.TopRightButtons = Array( _
     CreateFABarButton(Chr(0xF054), "right") _
     ,CreateFABarButton(Chr(0xF053), "left") _
     ,CreateFABarButton(Chr(0xF00C), "v") _
     ,CreateFABarButton(Chr(0xF00D), "x"))
    NavControl.ToolBarVisible = True
End Sub


Private Sub CreateFABarButton(text As String, tag As Object) As BarButton
    Dim bb As BarButton
    Dim b As Button
    b.InitializeCustom("BarButton", 0xFF007AFF, 0xFFE3EBF4)
    b.CustomLabel.Font = Font.CreateNew2("FontAwesome", 24)
    b.Text = text
    b.Tag = tag
    b.SetLayoutAnimated(0, 1, 0, 0, 30, 40)
    bb.InitializeCustom(b)
    Return bb
End Sub

Private Sub BarButton_Click
    Dim b As Button = Sender
    Log(b.Tag & " was clicked")
End Sub

1. Please use [code]code here...[/code] tags when posting code.
2. This is B4i code.

 

[MikeFree]

is a aquivalent code available for B4A ?

has anyone a idea ?

 

[Erel]

We don't know what you are trying to do.

 

[MikeFree]

want to create and delete a button on runtime... is this possible with B4A ??

 

[Erel]

Of course. I recommend you to start with the programming guides: https://www.b4x.com/android/documentation.html
