To be clear, layouts are also views, but are rarely called that by the community.įigure 1 shows a list of classes that derive from the View class. It also collaborates with each child to determine the final rendering size. It's responsible for arranging the child views into position in the UI. A layout class is a View class that contains a collection of child views. Layouts (the arrangers) serve a different purpose. They are called controls or widgets in other UI frameworks. View classes (the controls) are responsible for gathering user input or showing information to the user.
Both are considered visual elements, share a common base class ( View), and are collectively known as Views. The visual elements in Xamarin.Forms fall into two separate categories: controls and arrangers. In this article, I'll look at the Xamarin.Forms layout views and show how to use them to build various UI design structures. It's these layouts that provide the means to building adaptive user interfaces. As systems have evolved, these layout tools have advanced too, adding features that simplify commonplace layout problems. Every UI framework has the notion of positioning and sizing elements on the screen. The app UI needs to adapt to these size and orientation changes, look good, and be functional.
Xamarin apps run on a variety of device sizes - from small phones to bigger tablets - and the devices can change from portrait to landscape mode in an instant.
