Here the RestaurantListFragment is still visible after I navigate To RestaurantDetailFragment

<?xml version="1.0" encoding="utf-8"?>
<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"
    android:id="@+id/nav_graph"
    app:startDestination="@id/restaurantListFragment">

    <fragment
        android:id="@+id/scanQRFragment"
        android:name="com.example.dine.ui.view.home.scan_qr.ScanQRFragment"
        android:label="fragment_scan_q_r"
        tools:layout="@layout/fragment_scan_q_r" />
    <fragment
        android:id="@+id/restaurantListFragment"
        android:name="com.example.dine.ui.view.home.restaurants.RestaurantListFragment"
        android:label="fragment_restaurant_list"
        tools:layout="@layout/fragment_restaurant_list" >
        <action
            android:id="@+id/action_restaurantListFragment_to_restaruntDetailFragment"
            app:destination="@id/restaruntDetailFragment"
            app:popUpTo="@id/restaurantListFragment" />
    </fragment>
    <fragment
        android:id="@+id/myPlateFragment"
        android:name="com.example.dine.ui.view.home.my_plate.MyPlateFragment"
        android:label="fragment_my_plate"
        tools:layout="@layout/fragment_my_plate" />
    <fragment
        android:id="@+id/accountFragment"
        android:name="com.example.dine.ui.view.home.account.AccountFragment"
        android:label="fragment_account"
        tools:layout="@layout/fragment_account" />
    <fragment
        android:id="@+id/restaruntDetailFragment"
        android:name="com.example.dine.ui.view.restaurant_detail.RestaruntDetailFragment"
        android:label="RestaruntDetailFragment"
        tools:layout="@layout/fragment_restarunt_detail" />
</navigation>

这是我用于此导航片段的导航图文件。

private fun onItemSelected() {
        findNavController().navigate(R.id.action_restaurantListFragment_to_restaruntDetailFragment)
}

我在某个动作上调用了 onItemSelected()方法,任何帮助都将非常有用。谢谢

从餐厅列表导航到RestaurantDetail片段时,就像这样。很久以来我一直在遭受这个问题的困扰
