导航视图高度我已设置为match_parent但它根本不匹配父项

Question

导航视图高度我已设置为match_parent但它根本不匹配父项 下面是xml代码：

<?xml version="1.0" encoding="utf-8"?>
<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">

    <RelativeLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:orientation="vertical"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

    <FrameLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/content">
    </FrameLayout>

    </RelativeLayout>

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">
        <ImageView
            android:id="@+id/moveimage"
            android:layout_width="50dp"
            android:layout_height="50dp"
            android:src="@drawable/ic_launcher"/>
    </RelativeLayout>

    <android.support.design.widget.NavigationView
        android:id="@+id/nav_view"
        android:layout_width="50dp"
        android:layout_height="match_parent"
        android:layout_gravity="start"
       android:fitsSystemWindows="true"
        android:background="#fff"
        app:headerLayout="@layout/nav_header" />
</android.support.v4.widget.DrawerLayout>
