我想绑定 BottomNagation 和 NagationView。但是“运行”会产生以下内容

app:menu="@menu/bottom_navigation"

问题出在资源菜单中。

这是一个菜单示例，其中一切正常：

<?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/action_favorites" android:enabled="true" android:icon="@drawable/ic_favorite_white_24dp" android:title="@string/text_favorites" app:showAsAction="ifRoom" /> <item android:id="@+id/action_schedules" android:enabled="true" android:icon="@drawable/ic_access_time_white_24dp" android:title="@string/text_schedules" app:showAsAction="ifRoom" /> <item android:id="@+id/action_music" android:enabled="true" android:icon="@drawable/ic_audiotrack_white_24dp" android:title="@string/text_music" app:showAsAction="ifRoom" /> </menu>
