B4A Class [B4X] [XUI] AS Bottom Menu V2

A better menu, can you find here

First, i spend a lot of time in creating views, some views i need by my self, but some views not and to create a high quality view cost a lot of time. If you want to support me, then you can do it here by Paypal or with a coffee. :)

This is the V2 of the ASBottomMenu, with more Features, less code than the V1, B4X optimized and more...

Why a new thread for this? Because i have develope the class from the ground new, the event names etc. have been changed. The V2 is not compatible with the V1.

Amazing class thanks, i just found a little bug if you enable EnableMiddleButtonAsTab and you click on already active tab the underline get little messy the solution i found is in underline_slide_animation_withtext_2

        If enable_middlebutton_astab = True Then
            Dim tmp As Double = xpnl_underline.Left - totab.Left  - 40dip/4
            Dim tmp As Double = xpnl_underline.Left - totab.Left  - 40dip/2
        End If
amazing work with calculations by the way ;)

if you want to see the halo effect on the middle button

Private Sub Middle_Button_Click_Handler
    If xui.SubExists(mCallBack, mEventName & "_MiddleButtonClick",0) Then
        CallSub(mCallBack, mEventName & "_MiddleButtonClick")
    End If
    RippleEffect(PanelMiddlebutton, Ripple_Effect_Color, 250)
End Sub

Private Sub RippleEffect (Parent As B4XView, Color As Int, Duration As Int)
    Dim cvs As B4XCanvas
    Dim p As B4XView = xui.CreatePanel("")
    Dim InnerRadius As Int = Parent.Height * 1.30
    If Parent.Width <> Parent.Height Then InnerRadius = Max(Parent.Width, Parent.Height) * 1.60
    p.SetLayoutAnimated(0, 0, 0, InnerRadius, InnerRadius)
    cvs.DrawCircle(cvs.TargetRect.CenterX, cvs.TargetRect.CenterY, cvs.TargetRect.Width / 2, Color, True, 0)
    Dim bmp As B4XBitmap = cvs.CreateBitmap
    Dim iv As ImageView
    Dim p As B4XView = iv
    Dim Radius As Int = InnerRadius/2
    Dim x As Int = Parent.Width/2
    Dim y As Int = Parent.Height/2
    Parent.AddView(p, x, y, 0, 0)
    p.SetLayoutAnimated(Duration, x - Radius, y - Radius, Radius * 2, Radius * 2)
    p.SetVisibleAnimated(Duration, False)
End Sub

Great bottom tab

However, changing the current tab in code does not change the current tab visually.
I've amended the code below to call the relevant click but this is a bit untidy and could probably be better written.

Public Sub setCurrentTab(tabnumber As Int)
    If tabnumber = 1 Or tabnumber = 2 Or tabnumber = 3 Or tabnumber = 4 Or tabnumber = 5 Then
        If current_tab <> tabnumber Then
          current_tab = tabnumber
      'extra code below:
      Select tabnumber
          Case 1
          Case 2
            Case 3
            Case 4
            Case 5
        End Select
        End If
            Log("Tab Number not in range")
    End If
End Sub

I tried to use setMiddleButtonSize but have no effect
I see it, the issue is in the Base_Resize Sub, i fix it.
I add a private global variable for the middle button size, this should fix the issue.

Can you try it now? i cant test it with B4I, because my Apple Dev. account has expired for 2 months.

  • Fix setMiddleButtonSize is not working

I had problems with the SetCurrentTab and finally I solved it by modifying one of the procedures.

Here I leave it.

Public Sub setCurrentTab(tabnumber As Int)
        Select Case tabnumber
            Case 1
                current_tab = tabnumber
            Case 2
                current_tab = tabnumber
            Case 3
                current_tab = tabnumber
            Case 4
                current_tab = tabnumber
            Case 5
                current_tab = tabnumber
            Case Else
                Log("Tab Number not in range")
        End Select
End Sub

I suppose that in later versions I can solve it in a more appropriate way.

A greeting.

zuerst mal: gute Arbeit, Danke.
Dann ein paar Fragen mit der Bitte um Antwort:
- wie kann die Value Anzeige ausgeblendet werden?
- wie kann die Textanzeige aus/eingeblendet werden?
- Was nützt mir die Aufzählung zahlreicher Funktionen, wenn ich sie nicht aurufen kann?

Danke für die Arbeit, würde das View schon gerne verwenden aber die Beschreibung ist schon dürftig.
Viele Grüße Günter

If it is neccessary to give my comment/questiones in English pleas inform me.

- wie kann die Textanzeige aus/eingeblendet werden?
ist das beides nicht das gleiche?
is not that the same?

Was nützt mir die Aufzählung zahlreicher Funktionen, wenn ich sie nicht aurufen kann?
Was soll das für eine Frage sein?
What's that for a question?

Hi there.

I've just downloaded this and I get the following errors:

Unknown member: underlineanimation
Unknown member: textvisible
Unknown member: textonly
Cannot access private member: middlebuttonvisible
Unknown member: middlebuttonastab
Unknown member: middlebuttonicon

Any clues as to why this may be?

My apologies, Alexander. My mistake.

I thought the ASBottomMenu.bas file was part of the example. I downloaded that file and linked to it and now there are no problems.

Thanks for your patience.
