The example activity created in this chapter has, of course, created a similar user interface (the change in background color and view type notwithstanding) as that created in the earlier “Manual XML Layout Design in Android Studio” chapter. If nothing else, this chapter should have provided an appreciation of the level to which the Android Studio Layout Editor tool and XML resources shield the developer from many of the complexities of creating Android user interface layouts.
There are, however, instances where it makes sense to create a user interface in Java. This approach is most useful, for example, when creating dynamic user interface layouts.
