ScrollView in SlidingUpPanel Never works

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. http://ift.tt/1KWtJBe

I've followed it 4 times today and every time my ScrollView scrolls and my SlidingUpPanelLayout does not allow scrolling.

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:layout_width="match_parent"

    android:gravity="bottom"
    app:panelHeight="68dp"
    app:dragView="@+id/drag_view"

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

    <!-- MAIN CONTENT -->

    </FrameLayout>

Again check this for where I'm pulling code. http://ift.tt/1KWtJBe
