Anchor и BottomSheet

Хочу сделать, что бы когда BottomSheet появлялся на экране, что бы поднималась и View вместе с ним, для этого использую CoordinatorLayout и Anchor, проблема в том, что BottomSheet поднимается, а View остается внизу:

<android.support.design.widget.CoordinatorLayout

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

        android:background="@color/colorMain"
        android:titleTextColor="@color/colorWhite"
        android:layout_gravity="top"
        app:subtitleTextColor="@color/colorWhite"
        app:theme="@style/ToolbarTheme"></android.support.v7.widget.Toolbar>
    <android.support.v7.widget.RecyclerView
        android:id="@+id/rvChat"
        android:layout_marginTop="?attr/actionBarSize"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_above="@+id/rvWriteMessage"

        app:layout_anchorGravity="top|end"
        android:layout_above="@+id/rvIcons"
        android:layout_marginLeft="5dp">
        <!--android:layout_gravity="end|bottom"-->
        <View

            android:layout_above="@+id/rvInside"
            android:background="@color/colorGreyTransparent" />

        <RelativeLayout
            android:id="@+id/rvInside"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_alignParentBottom="true"
            android:layout_marginBottom="3dp"
            android:layout_marginRight="2dp"
            android:background="@color/colorWhite"
            >

            <ImageView
                android:id="@+id/imgSticker"
                android:layout_width="36dp"
                android:layout_height="36dp"
                android:layout_alignParentLeft="true"
                android:layout_centerVertical="true"
                android:background="@drawable/ic_tag_faces_24dp" />
            <io.github.rockerhieu.emojicon.EmojiconEditText
                android:id="@+id/etMessage"

                android:layout_centerVertical="true"
                android:layout_marginLeft="50dp"
                android:layout_marginRight="5dp"
                android:layout_toLeftOf="@+id/imgCamera"
                android:background="@drawable/rectangle_edit_text"
                android:hint="@string/conversation_activity_hint"
                android:textCursorDrawable="@color/colorMain"
                emojicon:emojiconSize="32sp" />
            <ImageView

                android:background="@drawable/circle_button"
                android:padding="7dp"
                android:src="@drawable/ic_add" />

            <ImageView
                android:id="@+id/btnSend"
                android:layout_width="36dp"
                android:layout_height="36dp"
                android:layout_alignParentRight="true"
                android:layout_centerVertical="true"
                android:layout_margin="5dp"
                android:background="@drawable/button_rectangle"
                android:padding="7dp"
                android:src="@drawable/ic_send" />
        </RelativeLayout>
    </RelativeLayout>

Layout для BottomSheet:

<?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:id="@+id/llBottomSheet"
    android:layout_width="match_parent"
    android:layout_height="200dp"
    android:background="@android:color/darker_gray"
    android:orientation="vertical"
    app:behavior_hideable="true"
    app:behavior_peekHeight="200dp"
    app:layout_behavior="android.support.design.widget.BottomSheetBehavior">

    <TextView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:gravity="center"
        android:layout_alignParentBottom="true"
        android:text="Bottom sheet content"
        android:textColor="@android:color/white" />
</RelativeLayout>

Что сейчас получается при подъеме BottomSheet (rvWriteMessage остается внизу экрана):
