Android Question Material design - Elevation

[Pendrush]

Panel1.Color = Colors.Yellow ' <- comment this line
Panel1.Elevation = 10dip

If I comment line Panel1.Color = Colors.Yellow, then panel get elevation.
When I try to change panel.color, panel don't accept elevation.
Tested on Nexus 5 android 6.0.1.
I actuality need to change panel color with some elevation, anyone know how?

did you try it with colordrawable and background? something like this:

    Dim cd As ColorDrawable
    cd.Initialize(Colors.Yellow,0dip)
    p.Background = cd

I haven't tried this, because I have an old version of B4A ...

Yes, but effect is the same, after color changing, panel lost shadow, but when i try Log (Panel1.Elevation) I can see that elevation is set, but no shadow at all.

It looks like a bug in Android. Might be related to this: https://code.google.com/p/android/issues/detail?id=78248

As a workaround you can use SetColorAnimated with a duration of 1 (1ms) to change the color:

Panel1.SetColorAnimated(1, 0, Colors.Yellow)

I have try everything but SetColorAnimated.
Thank you.
