title: How to put content inside android with navigation drawer template
body: <p>Im' new to android development, I'm creating new project android with template that having navigation drawer. it show the if - else state on selected menu item on drawer. and the content part suppose to be on main_content.xml.</p>
  
  <p>My question is: how to change content of the main content part when i select different menu? if i load another intent, it will have different design, unless i copy the layout all over again, but it would be repetitive and hard to maintain.</p>
  
  <p>Or is there any other way to do it?</p>
