嗨，CollapsingToolbar嵌套滚动不起作用，也不能在 android 中折叠工具栏

<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <android.support.design.widget.AppBarLayout
        android:id="@+id/MyAppbar"
        android:layout_width="match_parent"
        android:layout_height="256dp"
        android:fitsSystemWindows="true">

        <android.support.design.widget.CollapsingToolbarLayout
            android:id="@+id/collapse_toolbar"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:background="@color/material_deep_teal_500"
            android:fitsSystemWindows="true"
            app:layout_scrollFlags="scroll|exitUntilCollapsed">

            <FrameLayout
                android:layout_width="match_parent"
                android:layout_height="wrap_content">
                <LinearLayout
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content">
                    <ImageView
                        android:id="@+id/bgheader"
                        android:layout_width="match_parent"
                        android:layout_height="match_parent"
                        android:background="@drawable/ssss"
                        android:fitsSystemWindows="true"
                        android:scaleType="centerCrop"
                        app:layout_collapseMode="parallax" />
                </LinearLayout>
                <ImageView
                    android:id="@+id/ddd"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:layout_gravity="bottom|end"
                    android:layout_margin="15dp"
                    android:background="@drawable/dedd"
                    />
            </FrameLayout>
            <android.support.v7.widget.Toolbar
                android:id="@+id/MyToolbar"
                android:layout_width="match_parent"
                android:layout_height="?attr/actionBarSize"
                app:layout_collapseMode="pin" />

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


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

        <android.support.v4.widget.NestedScrollView
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_gravity="fill_vertical"
            android:fillViewport="true"
            android:layout_below="@+id/MyAppbar"
               app:layout_behavior="@string/appbar_scrolling_view_behavior">

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

        </android.support.v4.widget.NestedScrollView>



</RelativeLayout>

我根据whatsapp显示组名和图像。当滚动孔页面折叠工具栏和listview显示像whatsapp一样。
