Keeping a view at the bottom with the SlidingUpPanel library

I am using the SlidingUpPanel library in one of my Media Player apps.

In the slide panel, I have the media controls and I would like to display the track's artwork on top. The problem I am having is that I would like the media controls to always stay at the bottom of the screen. Maybe like a parallax effect (not sure if that is the right name). This is what I have for now:

Collapsed / Expanded / Dragging:

As you can see, while I drag the panel, the controls stick to the top. I would like it to stick to the bottom of the screen and have the artwork show right above it.

I was thinking of CoordinatorLayout, but I have no clue how that works!

My Code:

activity.xml

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

    <com.sothree.slidinguppanel.SlidingUpPanelLayout
        android:id="@+id/sliding_layout"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:gravity="bottom"
        sothree:umanoPanelHeight="92dp"
        sothree:umanoShadowHeight="4dp">

        <ListView
            android:layout_width="match_parent"
            android:layout_height="match_parent"/>

        <include layout="@layout/details_slide_bar" />
    </com.sothree.slidinguppanel.SlidingUpPanelLayout>

</RelativeLayout>

details_slide_bar.xml

<LinearLayout
              android:layout_width="match_parent"
              android:layout_height="match_parent"
              android:layout_gravity="bottom"
              android:orientation="vertical">

    <ImageView
        android:id="@+id/ivArtworkBar"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:visibility="gone"/>

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="92dp"
        android:orientation="horizontal"
        android:id="@+id/lDetailsBar">

        /!-- Content of the detalBar !-->
    </RelativeLayout>
</LinearLayout>

For now, I am only checking the state of the panel and adjusting the artwork's visibility accordingly.

There must be another way!
