Stop scroll on CollapsingToolbarLayout so it doesn't completely collapse

Question

I have a CollapsingToolbarLayout setup and im placing a wallpaper there. I want to be able to stop it from collapsing all the way.

I have tried minheight and many other things but can't figure it out.

How can i get it to stop collapsing to the second screenshot?

CollapsingToolbarLayout works really closely with Toolbar and as such the collapsed height depends on the toolbar.

I was able to solve your problem using this layout (Note it goes into the normal CoordinatorLayout/AppBarLayout Setup, With Fab and a NestedScrollView or RecyclerView):

<android.support.design.widget.CollapsingToolbarLayout
    android:id="@+id/collapsing_toolbar"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    app:layout_scrollFlags="scroll|exitUntilCollapsed"
    app:statusBarScrim="?attr/colorPrimaryDark"
    app:contentScrim="@android:color/transparent"
    app:titleEnabled="false"
    >
    <!-- There isnt a contentSCrim attribute so the toolbar is transparent after being
         collapsed
         Disabled the title also as you wont be needing it -->

    <ImageView
        android:id="@+id/image_v"
        android:layout_width="match_parent"
        android:layout_height="360dp"
        android:layout_gravity="center"
        android:scaleType="centerCrop"
        android:src="@drawable/md2"
        android:fitsSystemWindows="true"
        app:layout_collapseMode="parallax"
        tools:ignore="ContentDescription"
        />
        <!-- Normal Imageview. Nothing interesting -->

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="168dp"
        app:layout_collapseMode="pin"
        app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
        />
        <!-- The toolbar is styled normally. However we disable the title also in code.
        Toolbar height is the main component that determines the collapsed height -->

    <TextView
        android:text="@string/app_name"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom"
        android:background="?attr/colorPrimaryDark"
        android:paddingLeft="72dp"
        android:paddingRight="0dp"
        android:paddingBottom="24dp"
        android:paddingTop="24dp"
        android:textColor="@android:color/white"
        android:textAppearance="@style/TextAppearance.AppCompat.Headline"
        />
        <!-- The title textView -->

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

The related activity looks like this:

    ...
    setSupportActionBar((Toolbar) findViewById(R.id.toolbar));
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);

    // Disable toolbar title
    getSupportActionBar().setDisplayShowTitleEnabled(false);
    ...
