title: Move the Floating Action Button along with the swiped tab
body: <p>Let me brief about my idea and what I'm aiming to achieve, </p>
  
  <p>Idea is to have a swipe tab with three tabs in it and each tab screen being represented by a seperate Fragment class. I did this using the "it.neokree:MaterialTabs:0.11" library and everything is working well.
  Then I created a floating action button (FAB) using the "com.oguzdev:CircularFloatingActionMenu:1.0.2" library.</p>
  
  <p>Now <strong>what I'm trying to achieve is to fix this FAB to the fragment in the center tab and when I swipe the screen to go the previous or the next tab the FAB should slide out along with the tab fragment its in and should slide back in along with the center tab screen when I swipe back to it</strong>.    </p>
  
  <p>I have worked on it till now and now I'm able hide the view in other fragments and show it again in the center fragment by overriding the <code>setUserVisibleHint()</code> method in each fragment class like this.</p>
  
  <pre><code>@Override
  public void setUserVisibleHint(boolean isVisibleToUser) {
  super.setUserVisibleHint(isVisibleToUser);
     if (isVisibleToUser) {
         View tempView = getActivity().findViewById(R.id.myFAB);
         tempView.setVisibility(View.INVISIBLE);
        }
  }
  </code></pre>
  
  <p><strong>But the problem is I want the FAB to slide out and in along with the center tab just like other views in the tab's fragment class does, but my FAB is simply vanishing and reappearring.</strong></p>
  
  <p>In a way I want the FAB to be exclusive to the center tab and should be <strong>fixed</strong> to it.</p>
  
  <p>I also tried defining the FAB inside the center Fragment class but it doesn't seem to make any difference. Any Advice and suggestion will be very helpful. Thanks in advance</p>
