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 have solved the problem. Now android providing design library for material design, which has the FloatingActionButton. No need of customizing card view for floating action button.

Add design library in gradle dependencies

compile 'com.android.support:design:23.1.1'
