Started from v28 design support library we can use Material Card View, which provides us with a material styled cardview implementation out of the box.

You can further style the cardview by using two of the attributes that come with it:

• app:strokeColor - The colour to be used for the given stroke, this must be set in order to display a stroke
• app:strokeWidth - The width to be applied to the stroke of the view
