<!-- Wrapped in a CardView to simulate elevation of the main view.
  - There will be margins around the card on devices that are pre-Lollipop,
  - and the margin size is proportional to the set cardElevation. As a result, the
  - default item animation when collapsing/expanding the ViewHolder shows the views
  - that are common to both VHs (primarily the time text and the on-off switch)
  - shifting slightly during the transition. We are neglecting this blight because
  - we don't expect many devices below Lollipop using our app.
  -->
<!-- TODO: Write a layout for v21 that instead uses the elevation attribute normally.
  - You may have to set a non-transparent background on the main view.
  - Alternatively, just keep the CardView because that takes care of the non-transparent
  - background issue for free.
