title: Android: Dynamically set text in Navgation Drawer error
body: <p>I am trying to set Text in navigation drawer through main class after user successfully logs in. It is working fine when I use the below code:</p>
  
  <pre><code> if(LoggedFlag==1) {
          setContentView(R.layout.activity_home_logged);
  
      }
      else{
          setContentView(R.layout.activity_home);
      }
  
      Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
      setSupportActionBar(toolbar);
  
      FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
      fab.setOnClickListener(new View.OnClickListener() {
          @Override
          public void onClick(View view) {
              Intent intent = new Intent(Home.this, AddTrek.class);
              startActivity(intent);
          }
      });
  
      DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
  
      ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
              this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
      drawer.setDrawerListener(toggle);
      toggle.syncState();
  
  
      NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
      navigationView.setNavigationItemSelectedListener(this);
      /*View hd = navigationView.inflateHeaderView(R.layout.nav_header_home);
      tvNavName = (TextView)hd.findViewById(R.id.tv_nav_name);
      tvNavName.setText("hello");*/
  </code></pre>
  
  <p>But when I uncomment the setText part and run, I get two drawers one with the text that is set in xml file, and other with the text "hello".
  what changes do I have to make here to get only one drawer with the text that I pass through main class. </p>
