Android Question How to set the "focus" color of buttons in the manifest

My app has a bunch of buttons in it. The app runs on an Amazon Firestick, so it uses the remotes "D-Pad" to navigate among the buttons.

When a button gets the "focus", it changes color (hilights). But the color change from normal button background to hilight background is very small and hard to notice.

I want to make the difference between the button's normal background color and "focus" background color have more contrast so its real easy to see which button has the focus.

I am hoping this can be done via a theme in the manifest instead of having to add code in each buttons "Got_Focus" event.

But I can't figure out how to do this - I have no idea what the name of that color attribute is.

Any help will be greatly appreciated.

I was hoping there was a way to set the focused color through a theme so I wouldn't have to manually run code for each button, but I guess that is not possible.

Thanks for the suggestion.

I ended up creating a sub to automatically format the buttons even if I add new ones in the future:

B4X: 
Sub FormatButtons(P as Panel)

    Dim Focused, NotFocused As ColorDrawable
    Focused.Initialize(Colors.Blue, 0dip)
    NotFocused.Initialize(Colors.RGB(100,100,100),0)
 
    For Each v As View In P
     
        If GetType(v).ToLowerCase = "android.widget.button" Then

            Dim sld As StateListDrawable
            sld.Initialize
            sld.AddState(sld.State_Focused, Focused)
            sld.AddState(sld.State_Enabled, NotFocused)

            v.Background = sld
         
        End If
     
    Next

End Sub
