title: Android NavigationDrawerFragment layout appears in the fragments
body: <p>I am programming an application in Android Studio and I decided to use the NavigationDrawerActivity for the main screen activity. Automatically, Android Srudio creates two .java classes (Main.java an NavigationDrawerActivity.java) and three layouts.</p>
  
  <p>My problemis: when I want to put a button in the main screen (where the navigation drawer can be opened, of course), the other Fragments that are accessed from the Navigation Drawer have also the button of the main Activity. I mean, the layout of the main activity doesný dissappear from the fragments!</p>
  
  <p>What can I do?</p>
  
  <p>Thank you so much!</p>
