我的XML
<LinearLayout

xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"

您必须将抽屉布局作为父元素,因此您的布局将成为
<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/drawerLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#71b6ca"
>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
android:orientation="vertical">
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#71b6ca"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:title="DocVids"/>
<FrameLayout
android:id="@+id/containerView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
</FrameLayout>
<android.support.design.widget.NavigationView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/mynav"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:layout_marginTop="-24dp"
app:menu="@menu/drawer"//Your drawer menu consisting of menu items
/>
</LinearLayout>
</android.support.v4.widget.DrawerLayout>
示例以获取有关在您的我的xml中使用导航菜单的更多信息
使导航抽屉的xml如下所示:
将抽屉布局作为父布局
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:openDrawer="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:fitsSystemWindows="true"
app:headerLayout="@layout/nav_header_home"
app:menu="@menu/activity_home_drawer" />
</android.support.v4.widget.DrawerLayout>
我搞错了,我只是无意中从XML中删除了菜单和其他内容,现在它的背面与父视图的线性布局相同,但是我正在考虑您的答案谢谢您的帮助:)
