Xamarin.Forms Custom Renderers
Xamarin.Forms user interfaces are rendered using the native controls of the target platform, allowing Xamarin.Forms applications to retain the appropriate look and feel for each platform. Custom Renderers let developers override this process to customize the appearance and behavior of Xamarin.Forms controls on each platform.
Custom renderers provide a powerful approach for customizing the appearance and behavior of Xamarin.Forms controls. They can be used for small styling changes or sophisticated platform-specific layout and behavior customization. This article provides an introduction to custom renderers, and outlines the process for creating a custom renderer.
Every Xamarin.Forms control has an accompanying renderer for each platform that creates an instance of a native control. This article lists the renderer and native control classes that implement each Xamarin.Forms page, layout, view, and cell.
Entry control allows a single line of text to be edited. This article demonstrates how to create a custom renderer for the
Entry control, enabling developers to override the default native rendering with their own platform-specific customization.
ContentPage is a visual element that displays a single view and occupies most of the screen. This article demonstrates how to create a custom renderer for the
ContentPage page, enabling developers to override the default native rendering with their own platform-specific customization.
Xamarin.Forms.Maps provides a cross-platform abstraction for displaying maps that use the native map APIs on each platform, to provide a fast and familiar map experience for users. This topic demonstrates how to create custom renderers for the
Map control, enabling developers to override the default native rendering with their own platform-specific customization.
ListView is a view that displays a collection of data as a vertical list. This article demonstrates how to create a custom renderer that encapsulates platform-specific list controls and native cell layouts, allowing more control over native list control performance.
ViewCell is a cell that can be added to a
TableView, which contains a developer-defined view. This article demonstrates how to create a custom renderer for a
ViewCell that's hosted inside a Xamarin.Forms
ListView control. This stops the Xamarin.Forms layout calculations from being repeatedly called during
WebView is a view that displays web and HTML content in your app. This article explains how to create a custom renderer that extends the
Xamarin.Forms custom user interfaces controls should derive from the
View class, which is used to place layouts and controls on the screen. This article demonstrates how to create a custom renderer for a Xamarin.Forms custom control that's used to display a preview video stream from the device's camera.
This article shows how to write renderers to implement a custom
VideoPlayer control that can play videos from the web, videos embedded as application resources, or videos stored in the video library on the user's device. Several techniques are demonstrated, including implementing methods and read-only bindable properties.
