Answer 1

   FirebaseAuth firebaseauth = FirebaseAuth.getInstance(); 

   NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);   //displays text of header of nav drawer.
    View headerview = navigationView.getHeaderView(0);

    TextView tt1 = (TextView) headerview.findViewById(R.id.textview_username);
    tt1.setText(firebaseauth.getCurrentUser().getDisplayName());//username of logged in user.  

   TextView tt = (TextView) headerview.findViewById(R.id.textView_emailid);
    tt.setText(firebaseauth.getCurrentUser().getEmail());    //email id of logged in user.

    final ImageView img1 = (ImageView) headerview.findViewById(R.id.imageView_userimage);
    Glide.with(getApplicationContext())
            .load(firebaseauth.getCurrentUser().getPhotoUrl()).asBitmap().atMost().error(R.drawable.ic_selfie_point_icon)   //asbitmap after load always.
            .into(new SimpleTarget<Bitmap>() {
                @Override
                public void onResourceReady(Bitmap resource, GlideAnimation<? super Bitmap> glideAnimation) {
                    img1.setImageBitmap(resource);
                }
            });

The textview and imageview are from @layout/nav_header_main.xml

If you're using bindings you can do

val headerView = binding.navView.getHeaderView(0)
val headerBinding = NavDrawerHeaderBinding.bind(headerView)
headerBinding.textView.text = "Your text here"

Answer 3

As mentioned in the bug 190226, Since version 23.1.0 getting header layout view with: navigationView.findViewById(R.id.navigation_header_text) no longer works.

A workaround is to inflate the headerview programatically and find view by ID from the inflated header view.

For example:

View headerView = navigationView.inflateHeaderView(R.layout.navigation_header);
headerView.findViewById(R.id.navigation_header_text);

Ideally there should be a method getHeaderView() but it has already been proposed, let's see and wait for it to be released in the feature release of design support library.

I know this is an old post but i am sure that this might help someone down the road.

You can simply get the headerView element of the Navigation view by doing this:

 NavigationView mView = ( NavigationView ) findViewById( R.id.nav_view );

 if( mView != null ){
     LinearLayout mParent = ( LinearLayout ) mView.getHeaderView( 0 );

     if( mParent != null ){
        // Set your values to the image and text view by declaring and setting as you need to here. 
     }
 }

I hope that this helps someone.
