Android CollapsingToolbarLayout without Toolbar to stop at a certain point and not completely close

Question

I understand that a toolbar is needed so that the CollapsingToolbarLayout does not completely close when you scroll: eg:

I'm trying to figure out if I can get away with the CollapsingToolbarLayout without a Toolbar in it and still won't completely close?

Here's my code:

<?xml version="1.0" encoding="utf-8"?>

                    android:layout_height="?attr/actionBarSize"
                    android:text="Nooo, don't close!"
                    android:background="@null"
                    app:layout_collapseMode="pin"
                    style="@style/ToolBarWithNavigationBack"/>
        </android.support.design.widget.CollapsingToolbarLayout>
    </android.support.design.widget.AppBarLayout>
    <android.support.v4.widget.NestedScrollView
        android:layout_width="match_parent"

It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum."
                android:lineSpacingExtra="6dp"

        </LinearLayout>

        app:layout_anchor="@id/linear_anchor"
        app:layout_anchorGravity="top|right|end"
        tools:ignore="RtlHardcoded" />

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

On this one, instead of it scrolling up to completely hide it, I want it to stop on this part of the Layout http://i.imgur.com/sN9Zzkj.png

Set minHeight to CollapsingToolbarLayout and you are done.
