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() {
                @Override
                public void onResourceReady(Bitmap resource, GlideAnimation glideAnimation) {
                    img1.setImageBitmap(resource);
                }
            });

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