title: CardView bottom border is cut off inside ScrollView android
body: <p>I am putting the cardview inside scrollview, we expect to see that at the bottom, the border should be shown（see pic below）. But its not. The problem is that I cannot scroll to the bottom to see the border of cardview.</p>
  
  <p>All the solutions on SO is to change layout_margins to paddings, but its not the case for cardview if we want to show the border. I basically tried everything. But still doesnt work.
