BottomNavigationView没有显示我的菜单,不知道该怎么办,我试过删除gradle中的依赖项,但它不起作用,我只是在学习android studio如何工作,所以也许我忘记了一些愚蠢的事情,请帮助我
how it looks like
content_main:
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout 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/ConstraintLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<com.google.android.material.bottomnavigation.BottomNavigationView
android:layout_width="0dp"
android:layout_height="60dp"
android:layout_gravity="bottom"
android:background="#297385"
android:visibility="visible"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:menu="@menu/bottom_menu"
tools:visibility="visible" />
</androidx.constraintlayout.widget.ConstraintLayout>
这是bottom_menu:
<?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/settings"
android:title="@string/settings"
android:icon="@drawable/settings"
app:showAsAction="ifRoom"
android:visible="true"
/>
<item
android:id="@+id/notes"
android:visible="true"
android:title="@string/notes"
android:icon="@drawable/note"
app:showAsAction="ifRoom"
/>
<item
android:id="@+id/shop_list"
android:visible="true"
android:title="@string/shop_list"
android:icon="@drawable/list"
app:showAsAction="ifRoom"
/>
<item
android:id="@+id/new_item"
android:visible="true"
android:title="@string/new_item"
android:icon="@drawable/ic_new"
app:showAsAction="ifRoom"
/>
</menu>
Gradle中的依赖项:

//
