Android Code Snippet Elevation Color

This extends Erels XUI shadow function to use the color parameter also in B4A, by using
setOutlineAmbientShadowColor and setOutlineSpotShadowColor
Works since API 28

Public Sub SetShadow (View As B4XView, Offset As Double, Color As Int)
    #if B4J
    Dim DropShadow As JavaObject
    'You might prefer to ignore panels as the shadow is different.
    'If View Is Pane Then Return
    DropShadow.InitializeNewInstance(IIf(View Is Pane, "javafx.scene.effect.InnerShadow", "javafx.scene.effect.DropShadow"), Null)
    DropShadow.RunMethod("setOffsetX", Array(Offset))
    DropShadow.RunMethod("setOffsetY", Array(Offset))
    DropShadow.RunMethod("setRadius", Array(Offset))
    Dim fx As JFX
    DropShadow.RunMethod("setColor", Array(fx.Colors.From32Bit(Color)))
    View.As(JavaObject).RunMethod("setEffect", Array(DropShadow))
    #Else If B4A
    Offset = Offset * 2
    View.As(JavaObject).RunMethod("setElevation", Array(Offset.As(Float)))
    View.As(JavaObject).RunMethod("setOutlineAmbientShadowColor",Array(Color ))
    View.As(JavaObject).RunMethod("setOutlineSpotShadowColor",Array(Color ))
    #Else If B4i
    View.As(View).SetShadow(Color, Offset, Offset, 0.5, False)
    #End If
End Sub

To set the alpha value of the shadow you need to add it to your manifest:
the default values in the Material and AppCompat themes as of API 28 are 0.039 (3.9%) for ambientShadowAlpha and 0.19 (19%) for spotShadowAlpha

SetApplicationAttribute(android:theme, "@style/MyAppTheme")

CreateResource(values-v20, theme.xml,
<resources>
    <style name="MyAppTheme" parent="@android:style/Theme.Material.Light">
        <item name="android:ambientShadowAlpha">0.1</item>
        <item name="android:spotShadowAlpha">0.4</item>
    </style></resources>)
