如何跨导航堆栈重用android片段(Android中的iOS标签栏实现)？

<com.google.android.material.bottomnavigation.BottomNavigationView
    android:id="@+id/bottomNavigationView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:menu="@menu/bottom_navigation_menu" />

<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:id="@+id/navigation_home"
        android:title="Home"
        android:icon="@drawable/ic_home" />
    <item
        android:id="@+id/navigation_dashboard"
        android:title="Dashboard"
        android:icon="@drawable/ic_dashboard" />
    <item
        android:id="@+id/navigation_notifications"
        android:title="Notifications"
        android:icon="@drawable/ic_notifications" />
</menu>

<navigation xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    app:startDestination="@id/homeFragment">

    <fragment
        android:id="@+id/homeFragment"
        android:name="com.example.app.HomeFragment"
        android:label="Home"
        tools:layout="@layout/fragment_home" />

    <fragment
        android:id="@+id/dashboardFragment"
        android:name="com.example.app.DashboardFragment"
        android:label="Dashboard"
        tools:layout="@layout/fragment_dashboard" />

    <fragment
        android:id="@+id/notificationsFragment"
        android:name="com.example.app.NotificationsFragment"
        android:label="Notifications"
        tools:layout="@layout/fragment_notifications" />
</navigation>

val navView: BottomNavigationView = findViewById(R.id.bottomNavigationView)
val navController = findNavController(R.id.nav_host_fragment)

navView.setupWithNavController(navController)
