This question has been ask a lot, but i have not seen a recent answer.

This in contained in my main activity :

<androidx.fragment.app.FragmentContainerView
    android:id="@ id/fragment_container_view"
    android:name="androidx.navigation.fragment.NavHostFragment"
    app:navGraph="@navigation/navigation_map" />

I have tried

-> The fragment manager is deprecated

-> The support fragment manager does not work

I would like to know what is the fragment loaded in my FragmentContainerView

CodePudding user response：

I'll use the supportFragmentManager as suggested

The findFragmentById was not working for it though, but this seen in another linked question goes well :

navHostFragment = supportFragmentManager.fragments.first()

And the the usual

wantedFragment = navHostFragment.getChildFragmentManager().getFragments().first()
