title: How to swipe fragment with button click
body: <p>I have two fragments and a MainActivity class. 
  Everything works fine, but I want to swipe fragments with onClick button. For example if I click the button on fragment A, it will swipe to fragment B. Where do I need to add the code? In MainActivity or in Fragments?</p>
