Android ScrollView clipping child elevation shadow

I was facing the same problem, I solved it by adding cardUseCompatPadding attribute to the card view:

app:cardUseCompatPadding="true"

The shadow will not be cut out or cropped after using this solution.

this just worked for me in a similar problem:

the right way to get a child view to show shadow is to set padding on the parent and set android:clipToPadding="false" on that parent.
