title: How do I expand CardViews to show more detail like Google Keep cards?
body: <p>I have some CardViews in my app and I want them to function like the cards in Google Keep. For example, when I click on a card that has text, it expands (with the animation) into another view. </p>
  
  <p>If you're not sure what I mean, create a note on the Google Keep Android app, tap on the card that appears when the note is created. This is exactly what I want to happen in my app. </p>
  
  <p>How do I go about doing this? </p>
