The first step is to make some configuration changes so that the toolbar contracts during an upward scrolling motion, and then expands on a downward scroll.
A scrim option is also available to designate the color to which the toolbar should transition during the collapse sequence.

To see these features in action, the app bar contained in the activity_card_demo.xml file will be modified to use the CollapsingToolbarLayout class together with the addition of an ImageView to better demonstrate the effect of parallax mode. The new view hierarchy that makes use of the CollapsingToolbarLayout is represented by the diagram in Figure 34-6:
Since the scroll flags property for the CollapsingToolbarLayout element include the enterAlways option, a downward scrolling motion will cause the app bar to expand once again.
