Changing fragment by touch like in Facebook Messenger : <p>How to make a changing fragment by touch like in Facebook Messenger ?<br>
Or maybe they are not fragments ?<br>
I mean swap screen from Messenges to Active or Groups or Conversations using a touch and swap left or right ( we have 4 in messenger)</p>

<p>These are fragments ?
Please for any tips.
I can not find anything on the net.</p>
