If you want to see the halo effect on tab.

B4X:
Private Sub TriggerTabClickEvent(t As B4XView)
    If CurrentTab = Tabs.IndexOf(t) + 1 Then Return
   
    RippleEffect( t, xui.Color_Gray, 250)

Add to WobbleMenu.bas.

B4X:
'https://www.b4x.com/android/forum/threads/b4x-xui-simple-halo-animation.80267/#content
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.Initialize(p)
    cvs.DrawCircle(cvs.TargetRect.CenterX, cvs.TargetRect.CenterY, cvs.TargetRect.Width / 2, Color, True, 0)
    Dim bmp As B4XBitmap = cvs.CreateBitmap
    p.RemoveViewFromParent
    Dim iv As ImageView
    iv.Initialize("")
    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
    p.SetBitmap(bmp)
    Parent.AddView(p, x, y, 0, 0)
    p.SetLayoutAnimated(Duration, x - Radius, y - Radius, Radius * 2, Radius * 2)
    p.SetVisibleAnimated(Duration, False)
    Sleep(Duration)
    p.RemoveViewFromParent
End Sub

Hi, Excellent library for bottom navigation. Thanks.

I need some help in this library.

  1. How to change color of bottom navigation bar.
  2. Please give a sample for tab click event
  3. Can you increase or reduce the number of tabs/icons

1) Are you planning add which tab is firstly selected? Because, setting this by currenttab at runtime, transition is visible.

Edit: Why so many 1,1,1,1,1,1..... at log when app starting?

Sorry for the late reply. I was busy last few days.
get some visual errors on real device when tapping on wobble menu buttons (wobble bottom/width 100%x) https://paste.pics/df4c15123692f97ea01f372bbda35095

and the second visual error is when i put wobble menu (same height and shorter. i didn't try with same width..) on panel which is on top https://paste.pics/bba6f58ed75f31563d141b217b293947

android v8 on device

way to fix that?
@stanks did you modified any code of this library?

1) Are you planning add which tab is firstly selected? Because, setting this by currenttab at runtime, transition is visible.
@yiankos1 No because that will look wired. This curve looks good in the center at startup.
Why so many 1,1,1,1,1,1..... at log when app starting?
Don't know. I'll check that today!
