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

        </LinearLayout>

    </android.support.v4.widget.NestedScrollView>

    <android.support.design.widget.FloatingActionButton
        android:layout_height="wrap_content"
        android:layout_width="wrap_content"

        app:layout_anchor="@id/appbar"
        app:layout_anchorGravity="bottom|right|end"/>

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

如您所见,NestedScrollView中的CardView高200dp,并在底部对齐.
