Issues supporting CardView

[Aaub]

Hello,

I create an issues because I noticed 2 things using the lib with CardView. First is my app crash as soon as I try to apply createSkeleton()onto a CardView. CardView actually extend ViewGroup so it means that it would be possible to apply such a method. I tried to put breakpoints everywhere but I was not able to find exactly what is happening. Here is the stackTrace :

The other thing I noticed is when I applySkeleton()onto a RecycleView with items based on a CardView, all the CardView style does not appear when the shimmer is playing. I loose the elevation and the cornerRadius which lead to flat my items.

I have not seen any issue going in that direction.

Thank you in advance for your help
