Как исправить «Ошибка привязки ресурсов Android»? используя NavigationView и фрагменты

Я хочу использовать бургер-меню для своего приложения Android Studio, и я пытаюсь следовать этому руководству: https://github.com/codepath/android_guides/wiki/Фрагмент-Навигация-Ящик

И в моем файле activity_main.xml у меня есть эта ошибка:

Android resource linking failed 
E:\Smoozy\Documents\Findcontent\app\src\main\res\layout\activity_main.xml:76:
 error: resource menu/drawer_view (aka com.example.findcontent:menu/drawer_view) not found.
error: failed linking file resources.

Вот мой каталог файлов:https://imgur.com/a/8bqT9rY

Мой drawer_view.xml находится в папке моего макета, и я попытался удалить «меню» из оператора кода app:menu = "@menu/drawer_view"/>.

 <!-- This DrawerLayout has two children at the root  -->
<android.support.v4.widget.DrawerLayout
    xmlns:android = "http://schemas.android.com/apk/res/android"
    xmlns:app = "http://schemas.android.com/apk/res-auto"
    android:id = "@+id/drawer_layout"
    android:layout_width = "match_parent"
    android:layout_height = "match_parent">
    <!-- The navigation drawer that comes from the left -->
    <!-- Note that `android:layout_gravity` needs to be set to 'start' -->
    <android.support.design.widget.NavigationView
        android:id = "@+id/nvView"
        android:layout_width = "wrap_content"
        android:layout_height = "match_parent"
        android:layout_gravity = "start"
        android:layout_weight = "1"
        android:background = "@android:color/white"
        app:menu = "@menu/drawer_view"/>

    <!-- This LinearLayout represents the contents of the screen  -->
    <FrameLayout
        android:layout_width = "match_parent"
        android:layout_height = "match_parent"
        android:orientation = "vertical">

        <!-- The ActionBar displayed at the top -->
        <include
            layout = "@layout/toolbar"
            android:layout_width = "match_parent"
            android:layout_height = "wrap_content" />

        <!-- The main content view where fragments are loaded -->
        <FrameLayout
            android:id = "@+id/flContent"
            app:layout_behavior = "@string/appbar_scrolling_view_behavior"
            android:layout_width = "match_parent"
            android:layout_height = "match_parent" />
    </FrameLayout>


</android.support.v4.widget.DrawerLayout>
</androidx.constraintlayout.widget.ConstraintLayout>

Это код, который пытается достичь этого:

public void selectDrawerItem(MenuItem menuItem) {
    // Create a new fragment and specify the fragment to show based on     nav item clicked
    Fragment fragment = null;
    Class fragmentClass;
    switch(menuItem.getItemId()) {
        case R.id.nav_first_fragment:
            fragmentClass = FirstFragment.class;
               getSupportFragmentManager().beginTransaction().replace(R.id.flContent, new FirstFragment()).commit();

            break;
        case R.id.nav_second_fragment:
            fragmentClass = SecondFragment.class;
            getSupportFragmentManager().beginTransaction().replace(R.id.flContent, new SecondFragment()).commit();
            break;
        case R.id.nav_third_fragment:
            fragmentClass = ThirdFragment.class;
            getSupportFragmentManager().beginTransaction().replace(R.id.flContent, new ThirdFragment()).commit();
            break;
        default:
            fragmentClass = FirstFragment.class;
    }

    try {
        fragment = (Fragment) fragmentClass.newInstance();
    } catch (Exception e) {
        e.printStackTrace();
    }

    // Insert the fragment by replacing any existing fragment
    FragmentManager fragmentManager = getSupportFragmentManager();
    fragmentManager.beginTransaction().replace(R.id.flContent, fragment).commit();

    // Highlight the selected item has been done by NavigationView
    menuItem.setChecked(true);
    // Set action bar title
    setTitle(menuItem.getTitle());
    // Close the navigation drawer
    mDrawer.closeDrawers();
}

// ...

Спасибо!
