title: hide fragments in frame layout android
body: <p>I'm using a frame layout to have more than one fragment in the same section of the screen.</p>
  
  <p>So, I have a frame layout tag and then few fragment tags under it in XML.
  So, I can see the overlap of these fragments. </p>
  
  <p>I want to hide all the fragments except the one I want to show. 
  Where should I call the hide function? </p>
