java code -

    NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
    navigationView.setNavigationItemSelectedListener(this);
    View header=navigationView.getHeaderView(0);
    textViewNavHeader =(TextView)header.findViewById(R.id.text_nav_view);

Try to add custom NavigationView.OnNavigationItemSelectedListener

NavigationView navigationView = findViewById(R.id.nav_view);
    navigationView.setNavigationItemSelectedListener(
            new NavigationView.OnNavigationItemSelectedListener() {
                @Override
                public boolean onNavigationItemSelected(MenuItem menuItem) {
                    // set item as selected to persist highlight
                    menuItem.setChecked(false);
                    // close drawer when item is tapped
                    mDrawerLayout.closeDrawers();

                    // Add code here to update the UI based on the item selected
                    // For example, swap UI fragments here

                    return true;
                }
            });
