Unable to get exact circle shape when using card view

Question

I\'m using card view for floating action button in android material design. I\'m using following code for get the circle

Answer 1

I tried your code and found out that the Cards were less round with respect to the increase in the card elevation value.Try setting it to zero and this at least makes it look better.

card_view:cardElevation="0dp";

But a probably better option would be to use the FloatingActionButton for the round button
