title: How to use Floating Button Over Vertical Scroll View?
body: <p>The Gmail Android App Floating Button</p>
  
  <p>I want to add a floating button over a scroll view in Android. Such that, even if I scroll the layout, the button should remain constant at the given position (bottom-right) in this case. Just like the Gmail android mobile app, they have a send mail button intact at the bottom-right and the background is scrollable.</p>
