Comment naviguer d'un fragment imbriqué à un fragment parent à l'aide de la navigation Jetpack?

J'ai la navigation principale: SplashFragment -> RegistrationFragment -> RootFragment

<fragment
    Android:id="@+id/splashFragment"
    Android:name="com.low6.low6.features.splash.SplashFragment"
    Android:label="Splash"
    tools:layout="@layout/fragment_splash" >
    <action
        Android:id="@+id/action_next"
        app:clearTask="true"
        app:destination="@id/registrationFragment" />
</fragment>

<fragment
    Android:id="@+id/registrationFragment"
    Android:name="com.low6.low6.features.registration.RegistrationFragment"
    Android:label="Register">
    <action
        Android:id="@+id/action_next"
        app:clearTask="true"
        app:destination="@id/rootFragment" />
</fragment>

<fragment
    Android:id="@+id/rootFragment"
    Android:name="com.low6.low6.core.RootFragment"
    Android:label="@string/home"
    tools:layout="@layout/fragment_root" />

Et j'ai imbriqué la navigation d'enregistrement: RegistrationPersonalFragment -> RegistrationContactFragment -> RegistrationSecurityFragment

<fragment
    Android:id="@+id/registrationPersonalFragment"
    Android:name="com.low6.low6.features.registration.RegistrationPersonalFragment"
    Android:label="Register">

    <action
        Android:id="@+id/action_next"
        app:destination="@+id/registrationContactFragment" />
</fragment>

<fragment
    Android:id="@+id/registrationContactFragment"
    Android:name="com.low6.low6.features.registration.RegistrationContactFragment"
    Android:label="Register">

    <action
        Android:id="@+id/action_next"
        app:destination="@+id/registrationSecurityFragment" />
</fragment>

<fragment
    Android:id="@+id/registrationSecurityFragment"
    Android:name="com.low6.low6.features.registration.RegistrationSecurityFragment"
    Android:label="Register">

    <action
        Android:id="@+id/action_next"
        app:destination="@+id/rootFragment" />
</fragment>

Comment rediriger du dernier RegistrationSecurityFragment imbriqué vers RootFragment en utilisant le composant de navigation Jetpack?

Actuellement

<action
    Android:id="@+id/action_next"
    app:destination="@+id/rootFragment" />

Et

   navigateTo(R.id.action_next)

Donne moi

Grâce à la réponse de @Vladimir, j'ai trouvé cette solution

val mainNavView = requireActivity().findViewById<View>(R.id.mainNavFragment)
Navigation.findNavController(mainNavView).navigate(R.id.action_next)

Vous pouvez le faire comme ça;

in Child Fragment

// parentFragment = getParentFragment() for Java
(parentFragment as MyParentFragment).myNavigationHandler(myArguments)

dans le fragment parent

fun myNavigationHandler(myArguments) {
    Navigation.findNavController(binding.root)
        .navigate(MyFragmentDirections.actionMyAction(myArguments))
}

Dans votre code, vous pouvez transmettre l'ID de ressource de l'action globale à la méthode navigate() pour chaque élément d'interface utilisateur.

your_button.setOnClickListener(new View.OnClickListener() {
   @Override
   public void onClick(View view) {
       Navigation.findNavController(view).navigate(R.id.main_fragment);
   }
});
