Which of these is NOT recommended in the Android Developer’s Guide as a method of creating an individual View?
A . Create by extending the android.view.View class.
B . Create by extending already existing View classes such as Button or TextView.
C . Create by copying the source of an already existing View class such as Button or TextView
D . Create by combining multiple Views.

View Answer

Answer: C

Explanation:

Incorrect:

A, B: All of the view classes defined in the Android framework extend View. Your custom view can also extend View directly, or you can save time by extending one of the existing view subclasses, such as Button.

D: When building complex applications, you’ll often want to reuse the same group of views in various places of the application. One way to solve this problem is by creating a view that encapsulates the logic and layout of a group of views so you can reuse them without duplicating code in various places of the project.
