title: How to set default checked item in NavigationView?
body: <p>When I click on the <code>NavigationView</code> item its selection color changes. But I don't know how to check the first element by default. </p>
  
  <pre><code>private void setupDrawerContent(NavigationView navigationView) {
    navigationView.setNavigationItemSelectedListener(
      new NavigationView.OnNavigationItemSelectedListener() {
        @Override
        public boolean onNavigationItemSelected(MenuItem menuItem) {
          menuItem.setChecked(true);
          mDrawerLayout.closeDrawers();
          return true;
       }
     });
  }
  </code></pre>
