title: Floating Action Menu Like Inbox app : What is best way to implement
body: <p>I am trying to make a floating menu like  <strong>Inbox</strong> app. As per the requirement , initially there should one Floating action button in bottom right corner of the Activity. I  have implement this without any  problem using material design  support library' <strong>FloatingActionButton</strong> class. Now the problem is when I clicked   or touch the floating Action button. In its onClick ,it should open a menu of  three more floating action button on the page just like the Inbox android app. Now how do I can implement this?</p>
  
  <p>What I am thinking right now for this  is ,open a new activity with transparent background and place 4 floating action button on this. 3 for menu items and  one  for closing these action menus and return back to previous activity.
  Second I can  use a fragment for the same  task.
  What should I use ?Activity  or  fragment as per android design support guidlines? Please suggest a better solution if anybody have any to implement the same.</p>
