title: CardView cardUseCompatPadding
body: <p>I am developing an Android app for both Lollipop and Previous versions.</p>
  
  <p>I am using CardView (This cardView does not have any child, it simply placed behind my View) to create shadow.</p>
  
  <p>But the problem arise when it runs on the pre Lollipop devices.  </p>
  
  <p>so I set cardUseCompatPadding to true. I am wondering if I could get the value of this compat padding?</p>
  
  <p>Is there anywhere I could find the reference to the value?</p>
