NavigationView从右侧滑动

Question

我使用Android支持设计库中的新NavigationView.它工作正常,但当我尝试从右侧设置它滑动时,它会遇到异常:

java.lang.IllegalArgumentException: No drawer view found with gravity LEFT

我的主要布局:

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

    <include layout="@layout/activity_main_content" />

    <android.support.design.widget.NavigationView
        android:id="@+id/navigationView"
        style="@style/NavigationView"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="right"
        app:headerLayout="@layout/header"
        app:menu="@menu/menu_drawer"/>

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

任何人都可以知道如何改变这个？我尝试将"layout_gravity"更改为"end",它给出了我同样的错误.
