title: How to replace the activity's fragment from the fragment itself?
body: <p>My application has a Fragment inside its Activity. I would like to programmatically replace the fragment by another one from the current fragment itself.</p>
  
  <p>For example, if I click on a button inside the fragment, the fragment should be replaced with another one, but the activity should remain the same.</p>
  
  <p>Is it possible? If so, how to do it?</p>
