How to refer to the Drawer Activity element?

I am starting to learn Android Studio and I have a question. I want to make an authorization in the application. Switching to DrawerActivity, so that the name and Email are displayed on the side. But when you try to write any information to this TextView IDE, it gives an error - supposedly my textview is null.
