Question

我看过有关此问题的其他文章，但似乎无法解决，所以我希望这只是我遗漏了一些明显情况的情况。

这是我的代码： MainActivity.XML

<androidx.drawerlayout.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"
    android:fitsSystemWindows="true">

    <androidx.constraintlayout.widget.ConstraintLayout
            android:id="@+id/coordinatorLayout"
            android:layout_width="match_parent"
            android:layout_height="match_parent">

        <com.google.android.material.appbar.AppBarLayout
                android:id="@+id/appBarLayout"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
                app:layout_constraintEnd_toEndOf="parent"
                app:layout_constraintStart_toStartOf="parent"
                app:layout_constraintTop_toTopOf="parent">

            <androidx.appcompat.widget.Toolbar
                    android:id="@+id/toolbar"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:background="@color/translation_panel_blue_open_mea"
                    android:minHeight="57dp"
                    android:padding="1dp"
                    app:layout_constraintTop_toTopOf="parent"
                    app:subtitleTextColor="@color/header_grey_mea"
                    app:titleTextColor="@color/header_grey_mea"
                     android:theme="@style/AppTheme">


            </androidx.appcompat.widget.Toolbar>


    </androidx.constraintlayout.widget.ConstraintLayout>

    <com.google.android.material.navigation.NavigationView
        android:id="@+id/nav_view"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:fitsSystemWindows="true"
        android:theme="@style/AppTheme"
        app:menu="@menu/burger_menu" />

</androidx.drawerlayout.widget.DrawerLayout>

burger_menu.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <group android:checkableBehavior="single">
        <item
            android:id="@+id/menuLogout"
            android:onClick="initUserLogout"
            android:title="@string/log_out">

        </item>
        <item
            android:id="@+id/menuItemTutorial"
            android:onClick="launchTutorialView"
            android:title="@string/tutorial">

        </item>

    </group>
</menu>

AppTheme

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
        <item name="windowActionBar">false</item>
        <item name="windowNoTitle">true</item>
    </style>

和我在initBurgerMenu中运行的MainActivity函数：

private fun initBurgerMenu(){
        mDrawerLayout = findViewById(R.id.drawer_layout)
        val navigationView: NavigationView = findViewById(R.id.nav_view)
        navigationView.setNavigationItemSelectedListener { menuItem ->
            // set item as selected to persist highlight
            menuItem.isChecked = true
            // close drawer when item is tapped
            mDrawerLayout.closeDrawers()
            when (menuItem.itemId) {
                R.id.menuLogout -> {
                   initUserLogout()
                }
                R.id.menuItemTutorial -> {
                    Toast.makeText(this, "tutorial", Toast.LENGTH_LONG).show()
                }
            }
            true
        }
    }

像这样关闭您的AppBarLayout标签

<com.google.android.material.appbar.AppBarLayout
        android:id="@+id/appBarLayout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent">

        <androidx.appcompat.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:minHeight="57dp"
            android:padding="1dp"
            app:layout_constraintTop_toTopOf="parent"
            android:theme="@style/AppTheme">


        </androidx.appcompat.widget.Toolbar>

</com.google.android.material.appbar.AppBarLayout>

您在xml中的导航视图来自com.google.android.material.navigation.NavigationView，并且您可能正试图从NavigationView扩展android.support.design.widget，如果这是问题所在，请删除导入并重新导入正确的包

我收到“错误夸大类com.google.android.material.navigation.NavigationView”
