但我正面临按照我的应用程序要求实现它的问题.
我想动态地扩展菜单资源并以编程方式更改底部导航视图的菜单项/标题.

inflateMenu(int menuResource) — Inflate a menu for the bottom navigation view using a menu resource identifier.

根据文件：

inflateMenu: void inflateMenu (int resId)
Inflate a menu resource into this navigation view.
Existing items in the menu will not be modified or removed.
Parameters
resId int: ID of a menu resource to inflate

尝试以编程方式使用此inflateMenu(int resID)方法导航视图抛出异常“未找到资源”

bottomNavigationView.inflateMenu(R.menu.bottom_navigation_menu);

是否有可能在没有任何第三方库的情况下实现它？

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    xmlns:app="http://schemas.android.com/apk/res-auto">
 
    <FrameLayout
        android:id="@+id/main_fragment_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_above="@+id/bottom_navigation" />
 
    <android.support.design.widget.BottomNavigationView
        android:id="@+id/bottom_navigation"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        app:itemBackground="@color/theme_action_bar_bg"
        app:itemIconTint="@color/white"
        app:itemTextColor="@color/white" />
</RelativeLayout>

菜单资源：

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">
    <item
        android:id="@+id/nav_bar_item_dashboard"
        android:enabled="true"
        android:icon="@drawable/ic_nav_bar_dashboard_24px"
        android:title="@string/nav_bar_item_dashboard"
        app:showAsAction="ifRoom" />
    <item
        android:id="@+id/nav_bar_item_people"
        android:enabled="true"
        android:icon="@drawable/ic_nav_bar_people_24px"
        android:title="@string/nav_bar_item_people"
        app:showAsAction="ifRoom" />
    <item
        android:id="@+id/nav_bar_item_classroom"
        android:enabled="true"
        android:icon="@drawable/ic_nav_bar_classroom_24px"
        android:title="@string/nav_bar_item_classrooms"
        app:showAsAction="ifRoom" />
 
    <item
        android:id="@+id/nav_bar_item_manage"
        android:enabled="true"
        android:icon="@drawable/ic_nav_bar_manage_24px"
        android:title="@string/nav_bar_item_manage"
        app:showAsAction="ifRoom" />
 
    <item
        android:id="@+id/nav_bar_item_more"
        android:enabled="true"
        android:icon="@drawable/ic_nav_bar_more_24px"
        android:title="@string/nav_bar_item_more"
        app:showAsAction="ifRoom" />
</menu>

在menuresource中以编程方式为“活动中的底部导航”视图进行充气：

navBar = (BottomNavigationView) findViewById(R.id.bottom_navigation);
    navBar.inflateMenu(R.menu.bottom_navigation_view);
