我正在尝试使用NavigationView创建一个Activity，但它在启动时会因ADB中的错误而一直崩溃。

这是我得到的错误：

这是我的活动布局：

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/drawer_layout"
android:fitsSystemWindows="true">

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

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

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

</LinearLayout>

<!-- 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/nav_view"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:layout_gravity="start"
    android:background="@android:color/white"
    app:menu="@menu/drawer_view" />

</android.support.v4.widget.DrawerLayout>

这是工具栏布局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="?attr/colorPrimary"
        app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
        app:layout_scrollFlags="scroll|enterAlways"/>

    <android.support.design.widget.TabLayout
        android:id="@+id/tab_layout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="?attr/colorPrimary"
        app:tabGravity="fill"
        app:tabMode="fixed" />

</LinearLayout>

我不确定是什么原因导致此错误。我已经对这段代码进行了几个小时的更改而没有解决方案（错误不断变化）。

编辑：menu / drawer_view：

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">

<group android:checkableBehavior="single">
    <item
        android:id="@+id/nav_scout"
        android:title="Scout" />
    <item
        android:id="@+id/nav_view"
        android:title="View" />
</group>

<item android:title="More options">
    <menu>
        <item
            android:id="@+id/nav_settings"
            android:icon="@drawable/ic_menu_manage"
            android:title="Settings" />
        <item
            android:id="@+id/nav_feedback"
            android:icon="@drawable/ic_menu_send"
            android:title="Help &amp; feedback" />
    </menu>
</item>
</menu>
