使用recyclerview时Android fragment 滚动所有元素

Question

我正在开发一个安卓应用。我正在使用 Fragment 和 RecyclerView。在我的屏幕上有 SearchView、标题、RecyclerView 和一个 Button。我想要如下图所示的屏幕。

但它会滚动所有 View 。底部按钮出现在 recyclerview 最后一个元素的最后。我的布局代码如下所示。

layout.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical"
        android:weightSum="1">

        <SearchView
            android:id="@+id/search_view"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_weight="0.25"
            android:queryHint="Search Item" />

        <LinearLayout
            android:id="@+id/lItemsHeader"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_marginLeft="5dip"
            android:layout_marginRight="5dip"
            android:layout_marginTop="2dip"
            android:layout_weight="0.25"
            android:background="@color/title_background">

            <TextView
                android:id="@+id/item2"
                style="@style/ItemsHeader"
                android:layout_width="wrap_content"
                android:layout_height="match_parent"
                android:layout_marginLeft="3dip"
                android:width="0dip"
                android:text="@string/caption_item"
                android:textColor="@color/background1" />
        </LinearLayout>

        <android.support.v7.widget.RecyclerView
            android:id="@+id/my_recycler_view"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_weight="0.25"
            android:scrollbars="vertical" />

        <LinearLayout
            androidrientation="horizontal"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_marginTop="60dp"
            android:layout_weight="0.25">

            <Button
                android:id="@+id/btn1"
                android:layout_width="75dp"
                android:layout_height="35dp"
                android:layout_marginBottom="2dp"
                android:layout_marginLeft="5dp"
                android:layout_marginRight="10dp"
                android:layout_weight="1"
                android:background="@color/title_background"
                android:text="Save &amp; Close"
                android:textColor="#FFFFFF"
                android:textSize="@dimen/text_size_small" />
        </LinearLayout>
    </LinearLayout>
</RelativeLayout>

如何解决问题？请帮助我。
