How to use CollapsingToolbarLayout above scrollview?

Question

I want to create this view with the parallax effect for the top banner.

I tried this but it doesn't work:

<?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"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

<android.support.design.widget.AppBarLayout
    android:layout_height="200dp"
    android:layout_width="match_parent">
    <android.support.design.widget.CollapsingToolbarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:layout_scrollFlags="scroll|exitUntilCollapsed">

        <android.support.v7.widget.AppCompatImageView
            android:layout_width="match_parent"
            android:layout_height="200dp"
            android:background="@drawable/main_banner"/>

    </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:background="@color/vahab_background">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical"
        android:background="@color/vahab_background">

        ...

    </LinearLayout>

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

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

All the views above the navigation bar are inflated in a fragment. I want the whole parallax thing in the home tab only.
