android CoordinatorLayout使用问题

[hahahahehehelalala]

再用CoordinatorLayout的时候有个问题，布局如下
<android.support.design.widget.CoordinatorLayout
android:id="@+id/cl"
android:layout_width="match_parent"
android:layout_height="wrap_content">

<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">

<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_scrollFlags="scroll">

<TextView
android:id="@+id/tv1"
android:layout_width="match_parent"
android:layout_height="200dp"
android:background="#ffffffff"
android:text="adfaafdadsfasdf"
app:layout_scrollFlags="scroll" />

<TextView
android:id="@+id/tv2"
android:layout_width="match_parent"
android:layout_height="20dp"
android:layout_below="@+id/tv1"
android:background="#ffffffff"
android:text="adsfasdflllllllllllll"
app:layout_scrollFlags="scroll" />
</RelativeLayout>

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

<ListView
android:id="@+id/list"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior">

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

我想实现在向上滑动listview时，上面的textview也跟着向上滑动，怎么设置呢

去掉 app:layout_scrollFlags="scroll"

换成recyclerview实现的
