膨胀菜单上的ResourceNotFoundException

问题描述 投票：0回答：1

我正在根据文档向我的项目中添加options_menu.xml的文档来尝试实现searchview：

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <menu xmlns:android="http://schemas.android.com/apk/res/android" name="options_menu">
        <item
            android:id="@+id/search"
            android:title="@string/search_title"
            android:icon="@drawable/ic_search"
            android:showAsAction="collapseActionView|ifRoom"
            android:actionViewClass="android.widget.SearchView" />
    </menu>
</resources>

并且我尝试在MainActivity.kt中添加菜单：

override fun onCreateOptionsMenu(menu: Menu?): Boolean {
    menuInflater.inflate(R.menu.options_menu, menu)
    return true
}

但是运行程序时出现以下错误：

我的activity_main.xml如下：

<?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"

    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <androidx.appcompat.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="#FFF"
        android:elevation="0dp"
        app:titleTextColor="@color/colorPrimary"
        android:theme="@style/ThemeOverlay.MaterialComponents.Toolbar.Surface"
        app:layout_constraintTop_toTopOf="parent"
        app:popupTheme="@style/ThemeOverlay.MaterialComponents.Toolbar.Primary" />


    <Button
        android:id="@+id/showNotifBtn"
        android:layout_width="wrap_content"
        android:layout_height="48dp"
        android:layout_marginEnd="36dp"
        android:text="Show Notification"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/toolbar" />

    <Button
        android:id="@+id/showLocationBtn"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Show Location"
        app:layout_constraintEnd_toStartOf="@+id/showNotifBtn"
        app:layout_constraintHorizontal_bias="0.614"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/toolbar" />

    <TextView
        android:id="@+id/locationText"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_marginStart="8dp"
        android:layout_marginTop="60dp"
        android:layout_marginEnd="8dp"
        android:text="TextView"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintHorizontal_bias="1.0"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/showLocationBtn" />

</androidx.constraintlayout.widget.ConstraintLayout>```

我只是遵循文档不知道出了什么问题，错误代码没有指定我缺少的资源。帮助。

您的options_menu应该在res -> menu下创建，并像这样

<?xml version="1.0" encoding="utf-8"?> <menu xmlns:android="http://schemas.android.com/apk/res/android"> <item android:id="@+id/search" android:title="@string/search_title" android:icon="@drawable/ic_search" android:showAsAction="collapseActionView|ifRoom" android:actionViewClass="android.widget.SearchView" /> </menu>
