title: Android keep Nav Bar across Activities
body: <p>(I'm not sure if it's the correct terminology but Navbar is referring to the slide-out menu that's common to android apps)</p>
  
  <p>I'm new to Android development and had a question about keeping the same Navbar across screens. I noticed the default created layout (activity_main.xml by default) says to include the layout holding the content (content_main.xml by default).</p>
  
  <p>My question is would it be easier to create new activities and load the Navbar into them, somehow switch out the content_main.xml when an option from the Navbar is selected, or is there another option I'm not considering?</p>
