Android:如何从单个按钮到多个片段的导航器进行交易？

<navigation xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">
    <fragment
        android:id="@+id/firstFragment"
        android:name="com.example.FirstFragment"
        android:label="First Fragment" >
        <action
            android:id="@+id/action_firstFragment_to_secondFragment"
            app:destination="@id/secondFragment" />
    </fragment>
    <fragment
        android:id="@+id/secondFragment"
        android:name="com.example.SecondFragment"
        android:label="Second Fragment" />
</navigation>

<androidx.fragment.app.FragmentContainerView
    android:id="@+id/navHostFragment"
    android:name="androidx.navigation.fragment.NavHostFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:defaultNavHost="true"
    app:navGraph="@navigation/navigation" />

val navController = Navigation.findNavController(this, R.id.navHostFragment)

button.setOnClickListener {
    navController.navigate(R.id.action_firstFragment_to_secondFragment)
}
