Can repro this issue at android platform on the latest 17.11.0 Preview 1.0(8.0.60-ci.net8.24273.1/8.0.40).

Looking at this some more, I see the following with each of the buttons:

• no background => "use default OS background" - so for image buttons, the OS does not have a ripple
• transparent => this has a ripple, but it is not visible since the ripple is white and appears under the image
• white => this has a ripple but it is not visible since the ripple is white and appears under the image
• color => the white ripple is visible and under the image.

Since ImageButton has no ripple so it feels wrong, I will make sure it gets a ripple if no background is set.

For normal Button, there is a RippleColor property, but for the ImageButton, it is all fake as an image button is not a thing supported by Android and we are using a fancy image control.

But, changing the ripple color sounds like a feature request and we could see about adding that if people want it.

The standard buttons also have this behaviour. The problem could be the background color from the button or from the parent element. If the color is white, transparent or not set no ripple is not working.

Perhaps it makes sense -if possible- to set a colour for the ripple. If the ripple is always white and is sometimes not visible the user has not the android typical feedback.

Interesting. I didn't know that. Is this accessable via platform specific code: On<Android>() or via handler?

Thank you

This is not really a xplat feature, so we don't have an api for it. But, if you want you can add your own mapper for Android. And maybe even your own attached property - or even an effect to not have to do anything.

PlatformView.RippleColor = color.ToPlatform();

That in an effect is all that is needed.
