put card.xml in your drawables directory, put colors.xml in your values directory or add the colors to your colors.xml file.


set the background of a view to card,
as you can see in card.xml the drawable handles the card margin, so you don't have to add a margin to your view


 ``` xml
<View 
  android:layout_width="fill_parent"
