Well, I think you need to add this line app:layout_behavior="@string/appbar_scrolling_view_behavior" in your RecyclerView

Eg:

    <android.support.v7.widget.RecyclerView
        android:id="@+id/recyclerView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:layout_behavior="@string/appbar_scrolling_view_behavior" />

Most importantly you will also need to add xmlns:app="http://schemas.android.com/apk/res-auto" in coordinatorLayout tag.

Another point: Make sure you're using com.android.support:recyclerview-v7:22.2.0 with prior version it might not work properly

Hope it helps.
