The Android framework has a large set of {@link android.view.View} classes for
|
||
interacting with the user and displaying various
|
||
types of data. But
|
||
sometimes your app has unique needs that aren’t covered by the built-in views. This class shows you
|
||
how to create your
|
||
own views that are robust and reusable.</p>
