try this out:

Using FrameLayout as child of CoordinatorLayout works quite well. The toolbar is collapsing like it's supposed to. I had a problem in the beginning, when I used outdated libraries.
Here are the gradle dependencies I'm using right now:
compile 'com.android.support:appcompat-v7:22.2.1'
compile 'com.android.support:cardview-v7:22.2.0'
compile 'com.android.support:recyclerview-v7:22.2.0'
compile 'com.android.support:design:22.2.0'
I'm using `FrameLayout` with the attribute `app:layout_behavior="@string/appbar_scrolling_view_behavior"` as a child of `CoordinatorLayout` in an activity's layout. The `FrameLayout` serves as container for fragments. My fragment layouts' root elements are either a `RecyclerView` or a `NestedScrollView`.
Here is the layout of the activity:
<android.support.design.widget.CoordinatorLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<FrameLayout
android:id="@+id/..."
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior"
/>
<android.support.design.widget.AppBarLayout
android:layout_height="192dp"
android:layout_width="match_parent"
>
<android.support.design.widget.CollapsingToolbarLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_scrollFlags="scroll|exitUntilCollapsed"
>
<ImageView
android:id="@+id/.."
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
android:scaleType="centerCrop"
android:src="@drawable/..."
app:layout_collapseMode="parallax"/>
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar_sessions"
android:layout_height="?attr/actionBarSize"
android:layout_width="match_parent"
app:layout_collapseMode="pin"
/>
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
</android.support.design.widget.CoordinatorLayout>
My first fragment's layout looks like this:
<android.support.v7.widget.RecyclerView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:scrollbars="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="..."
/>
My second fragment's layout looks like this:
<android.support.v4.widget.NestedScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="..."
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="..."
>
...
</android.support.v4.widget.NestedScrollView>
