我创建了一个MainActivity的项目，它有两个标签（和两个片段）。
我尝试添加NavigationDrawer，但我遇到了一些错误，说我无法在tabView旁添加此错误。我怎么能正确地做到这一点？
这是我的MainActivity：

以下是我layout activity_fragment MainActivity的{{1}}：
<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">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<include
layout="@layout/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<FrameLayout
android:id="@+id/flContent"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
<android.support.design.widget.NavigationView
android:id="@+id/nvView"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="@android:color/white"
app:menu="@menu/drawer_view"
app:headerLayout="@layout/nav_header">
</android.support.design.widget.NavigationView>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/activity_fragment"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context="com.drgnme.listhamrah.MainActivity">
<android.support.v4.view.ViewPager
android:id="@+id/viewpager"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
</RelativeLayout>
</android.support.v4.widget.DrawerLayout>
这是nav_header.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="192dp"
android:background="?attr/colorPrimaryDark"
android:padding="16dp"
android:theme="@style/ThemeOverlay.AppCompat.Dark"
android:gravity="bottom">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Header"
android:textColor="@android:color/white"
android:textAppearance="@style/TextAppearance.AppCompat.Body1"/>
</LinearLayout>
这是toolbar.xml
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/toolbar"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:fitsSystemWindows="true"
android:minHeight="?attr/actionBarSize"
app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
android:background="?attr/colorPrimaryDark">
</android.support.v7.widget.Toolbar>
这是drawer_view.xml中的res/menu：
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<group android:checkableBehavior="single">
<item
android:id="@+id/nav_first_fragment"
android:icon="@drawable/ic_one"
android:title="One"
android:checked="true"/>
<item
android:id="@+id/nav_second_fragment"
android:icon="@drawable/ic_two"
android:title="Two"/>
<item
android:id="@+id/nav_third_fragment"
android:icon="@drawable/ic_three"
android:title="Three"/>
<item android:title="Sub items">
<menu>
<group android:checkableBehavior="single">
<item
android:icon="@drawable/ic_one"
android:title="Sub item 01"/>
<item
android:icon="@drawable/ic_three"
android:title="Sub item 02"/>
</group>
</menu>
</item>
</group>
</menu>
最后这是我在logcat中的错误：
