     39 The Android framework has a large set of {@link android.view.View} classes for
     40 interacting with the user and displaying various
     41 types of data. But
     42 sometimes your app has unique needs that arent covered by the built-in views. This class shows you
     43 how to create your
     44 own views that are robust and reusable.</p>
