    <android.support.design.widget.NavigationView
        android:id="@+id/nav_view"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"

        app:headerLayout="@layout/nav_header_navigation"
        app:menu="@menu/activity_navigation_drawer" />

</android.support.v4.widget.DrawerLayout>

查看NavigationView,可以看到　headerLayout，menu分别时抽屉的上下两部分，activity_navigation_drawer最好别用这个名称，否则可能加载系统默认布局怎么改都没用

    } 
    DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
    drawer.closeDrawer(GravityCompat.START);
    return true;
}

  • 动态修改　headLayout的内容

       View headerLayout = navView.getHeaderView(0);
  TextView tevtView = headerLayout.findViewById(R.id.textView);
  tevtView.setText("nishiminglema ");

注意　NavigationView也可以添加头部
