在RecyclerView下方显示LinearLayout

Question

我用a RecyclerView来显示一个项目列表,我想在列表下面显示一个包含一些细节的方框,但我不知道怎么做,我已经尝试了很多东西,但是我不能显示框我想.

我的想法是实现如下图所示:

以下是我的代码:

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
    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:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    tools:context="...MainActivity"
    android:background="@color/backgroundColor">

    <android.support.design.widget.AppBarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:theme="@style/AppTheme.AppBarOverlay">

        <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/AppTheme.PopupOverlay" />

    </android.support.design.widget.AppBarLayout>

    <android.support.v7.widget.RecyclerView
        android:id="@+id/user_subscriptions"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:paddingTop="12dp"
        android:paddingBottom="10dp"
        app:layout_behavior="@string/appbar_scrolling_view_behavior"/>


     // HERE I'M TRYING TO ADD THE BOX.


    <android.support.design.widget.FloatingActionButton
        android:id="@+id/fab"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom|end"
        android:layout_margin="@dimen/fab_margin"
        android:src="@drawable/ic_add" />

</android.support.design.widget.CoordinatorLayout>

不知道怎么办呢？谢谢!
