In the last chapter, we created a very simple but useful application using the screen framework provided by the BlackBerry SDK. We used only two of the
Field
classes though and there are many others to explore. In this chapter, we will dig into that framework more and explore each of otherField
classes in detail. The framework does a lot for us automatically, and we saw some of that in the last chapter as well. In this chapter, we will talk more about the services that are provided by the framework in detail.
Here are a few things that we will cover as we proceed through this chapter:
What is a
Field
What field styles are and how they can be used to change the appearance and behavior of a
Field
How to use common
Field
classes such asEditField
andChoiceField
Gain an understanding of what makes each field different and what specific features are implemented in each class
