How to use the views provided by Xamarin.Forms
Animation
Xamarin.Forms includes its own animation infrastructure that's straightforward for creating simple animations, while also being versatile enough to create complex animations.
BoxView
The BoxView is just a simple colored rectangle, but it can be used for decorative items, rudimentary graphics, and for obtaining interative touch input.
Colors
Defining and using colors across platforms can be tricky when each platform has its own standards and defaults.
Controls Reference
This document is a quick reference to the UI views that make up the Xamarin.Forms framework, such as Pages, Layouts, Views and Cells.
DataPages
DataPages provide an API to quickly and easily bind a data source to pre-built views. List items and detail pages will automatically render the data, and be customized using themes.
DatePicker
The DatePicker allows a user to select a date within a specified range. It is implemented using the date picker supported by the particular platform that the program is run on.
Graphics
How to incorporate graphics and game engine visuals into a Xamarin.Forms application.
Images
Images can be shared across platforms with Xamarin.Forms, they can be loaded specifically for each platform, or they can be downloaded for display.
Layouts
Xamarin.Forms has several layouts for organizing on-screen content. StackLayout, Grid, FlexLayout, AbsoluteLayout, ScrollView, and RelativeLayout can each be used to create beautiful, responsive user interfaces.
ListView
Xamarin.Forms provides a list view control to display scrolling rows of data. The control includes contextual actions, HasUnevenRows automatic sizing, separator customization, pull-to-refresh, and headers and footers.
Maps
Adding maps requires an additional NuGet package download and some platform-specific configuration. Maps and pin markers can be added in just a few lines of code once the configuration is done.
Picker
The Picker view is a control for selecting a text item from a list of data.
Slider
The Slider allows a user to select a numeric value from a continuous range.
Styles
Font, color, and other attributes can be grouped into styles which can be shared across controls, layouts, or the entire application using ResourceDictionaries.
TableView
The table view is similar to a list view, but rather than being designed for long lists of data it is intended for data-entry-style screens of scrolling controls or simple scrolling menus.
Text
Xamarin.Forms has several views for presenting and receiving text. Text views can be formatted and customized for platforms. Specific font settings can enable compatibility with accessibility features.
Themes
Xamarin.Forms Themes define a specific visual appearance for the standard controls. Once you add a theme to the application's resource dictionary, the appearance of the standard controls will change.
Visual State Manager
The Visual State Manager provides a structured way to trigger changes in the user interface from code, including layout that adapts to changes in device orientation or size.
WebView
Xamarin.Forms uses the native web browser control on each platform, and can display websites, local resources, and generated Html strings.
