use this to change the text of material Drawer

navigationView.getMenu().getItem(0).setTitle("any text");

or 

navigationView.getMenu().findItem(R.id.nav_calculator).setTitle("xxx");

Secondly your method of getting string is also not right the right way is 

String s= getResources().getString(R.string.appbar_scrolling_view_behavior);

TextView name = findViewById(R.id.username);

this is wrong because username is in the navigationHeader and not in view

so, you should to get NavigationHeader and then get username
for example

TextView name = navigationView.getHeaderView(0).findViewById(R.id.username);

You could try this:

TextView name = (TextView) navigationView.getHeaderView(0).findViewById(R.id.username);
