Android Question TabStripViewPager background color

[Zockolade]

Hi,
is it possible to change the tab background color in runtime?

Thanks!

This important code allows you to get the labels that make the tab headers:

Public Sub GetAllTabLabels (tabstrip As TabStrip) As List
   Dim jo As JavaObject = tabstrip
   Dim r As Reflector
   r.Target = jo.GetField("tabStrip")
   Dim tc As Panel = r.GetField("tabsContainer")
   Dim res As List
   res.Initialize
   For Each v As View In tc
     If v Is Label Then res.Add(v)
   Next
   Return res
End Sub

Example of changing the color of the current tab color:

Sub TabStrip1_PageSelected (Position As Int)
   Log($"Current page: ${Position}"$)
   Dim i As Int
   For Each lbl As Label In GetAllTabLabels(TabStrip1)
     If i = Position Then
       lbl.SetColorAnimated(200, Colors.Green, Colors.Yellow)
     Else
       lbl.Color = Colors.Green
     End If
     i = i + 1
   Next
End Sub

Note that you should call TabString1_PageSelected(0) in Activity_Create.

For Each lbl As Label In Utils.GetAllTabLabels(TabStrip1)
        lbl.Color = Colors.RGB(39 ,174,96)

Put GetAllTabLabels in the same module.

 

[Zockolade]

    For Each lbl As Label In GetAllTabLabels(TabStrip1)
        lbl.Color = Colors.RGB(39 ,174,96)
       Next

Unfortunately the same

I now understand what you mean with "I lost underline".

Use semi transparent colors:

For Each lbl As Label In GetAllTabLabels(TabStrip1)
     If i = Position Then
       lbl.Color = 0x300608C3
     Else
       lbl.Color = 0x300E4F03
     End If
     i = i + 1
   Next
