ScrollView in SlidingUpPanel Never works

Question

I have tried everything to get my ScrollView and SlidingUpPanelLayout to function how Google Maps app handles it. (video example)

This is the only link that seems to actually be working for people, but it is not working for me. https://stackoverflow.com/a/22720204/172336

I've followed it 4 times today and every time my ScrollView scrolls and my SlidingUpPanelLayout does absolutely nothing. (It sits there)

Here is the code I am adding to the code from the SlidingUpPanelLayout as seen on GitHub.

activity_main.xml

<com.bouy76.sportsmantracker.SlidingUpPanelLayout
    android:id="@+id/sliding_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:clipChildren="false"
    android:gravity="bottom"
    app:panelHeight="68dp"
    app:dragView="@+id/drag_view"

    app:scrollView="@+id/scroll_view"> <!-- attrs.xml tag -->

    <!-- MAIN CONTENT -->
    <FrameLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:gravity="top">

        <com.nutiteq.MapView
            android:id="@+id/main"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />

    </FrameLayout>

Again check this for where I'm pulling code. https://stackoverflow.com/a/22720204/172336
