Implementing Your First Custom View

In the previous chapter, we've seen how to create the foundations of a custom view, but unless we add some more features and customizations it'll be pretty useless. In this chapter, we'll continue building on top of these foundations, see how we can parameterize our custom view to allow either ourselves or any other developer to customize them, and at the end, cover some rendering that will enable us to build slightly more complex custom views.

In addition, as we've mentioned in the previous chapter, we can create custom layouts as well. In this chapter, we'll see how to create a simple custom layout.

In more detail, we'll cover the following topics:

• Measuring and parameterizing our custom view
• Instantiating custom views
• Creating custom layouts
• Basic rendering
