title: How to remove the default app navigation header on a android app?
body: <p>I seen some questions pertaining to this, however there solutions where to do it in the code. I would like to get rid of the navigation header that comes default on the android app when selecting a template.</p>
  
  <p>Now, I do not want to do this with java code. How can I remove the panel from my activity_main.xml?</p>
  
  <p>This is the header I am taking about:

  <p>I would like to remove it completely, not temporarily, to have more space to place elements in my app.</p>
