Update selected state of navigation drawer after back press

Whats the proper way to handle the selected state of the navigation drawer after back press?

I have a navigation drawer with n entries (in a listview) like the SDK sampl

Here is a solution in kotlin.

In the fragment that you want to be selected and highlighted by the drawer, you simply do:

    override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
    super.onViewCreated(view, savedInstanceState)

    val navView: NavigationView = activity!!.findViewById(R.id.nav_view)
    navView.setCheckedItem(R.id.name_of_this_fragment)

    ...
}
