ResourcesHelper.GetResourceColor("DarkSurface") private void TabButtonOnClicked(object sender, EventArgs e)Ĭolor sourceColor = TabButton.ButtonBackgroundColor Ĭolor targetColor = _currentTheme = Theme.Light You can see that I am not only changing colors, but also disabling shadows in dark mode, since dark modes are flat by essence.Īnd now let's see the code for our transition: SetDynamicResource(Elevation4dpColor, "OnSurfaceColor") SetDynamicResource(DynamicSecondaryTextColor, "TextSecondaryLightColor") SetDynamicResource(DynamicPrimaryTextColor, "TextPrimaryLightColor") SetDynamicResource(DynamicHasShadow, true) SetDynamicResource(DynamicBottomShadow, ShadowType.Bottom) SetDynamicResource(DynamicTopShadow, ShadowType.Top) SetDynamicResource(DynamicNavigationBarColor, "Accent") SetDynamicResource(Elevation4dpColor, "DarkElevation4dp") SetDynamicResource(DynamicSecondaryTextColor, "TextSecondaryDarkColor") SetDynamicResource(DynamicPrimaryTextColor, "TextPrimaryDarkColor") SetDynamicResource(DynamicHasShadow, false) SetDynamicResource(DynamicBottomShadow, ShadowType.None) SetDynamicResource(DynamicTopShadow, ShadowType.None) SetDynamicResource(DynamicBarTextColor, "TextPrimaryDarkColor") SetDynamicResource(DynamicNavigationBarColor, "DarkElevation2dp") Public static void SetDynamicResource(string targetResourceName, T value) Throw new InvalidOperationException($"key not found in the resource dictionary") Ī = value If (!(sourceResourceName, out var value)) Public static void SetDynamicResource(string targetResourceName, string sourceResourceName) Public const string Elevation4dpColor = nameof(Elevation4dpColor) Public const string DynamicHasShadow = nameof(DynamicHasShadow) Public const string DynamicBottomShadow = nameof(DynamicBottomShadow) Public const string DynamicTopShadow = nameof(DynamicTopShadow) Public const string DynamicBarTextColor = nameof(DynamicBarTextColor) Public const string DynamicBackgroundColor = nameof(DynamicBackgroundColor) Public const string DynamicNavigationBarColor = nameof(DynamicNavigationBarColor) Public const string DynamicSecondaryTextColor = nameof(DynamicSecondaryTextColor) Public const string DynamicPrimaryTextColor = nameof(DynamicPrimaryTextColor) In my Silly App! bottom bar I have a TabButton with a toggle theme icon, clicking on it will call either SetDarkMode() or SetLightMode(): namespace Sill圜.Views SetDynamicResource(DynamicBackgroundColor, "LightSurface") SetDynamicResource(DynamicBackgroundColor, "DarkSurface") ![]() You assign them dynamically in your code like this (we'll see the SetDynamicResource implementation right after that): // Dark Mode The catch with DynamicResource values is that you won't define it in your styles like classic StaticResource.įor example DynamicBackgroundColor is not defined anywhere in the xaml, you can regard them as references waiting to be assigned. We can see that DynamicResource works also with styles. Let's have a look at our App.xaml: #121212 The main impacted files by the theming are:įirst step is to swap StaticResource for DynamicResource every view properties that will be impacted by your theme update.ĭoing so, when you will set the DynamicBackgroundColor from black to white for example, it will be automatically propagated to all the properties referencing this key. An animated transition between the themes.Changing xaml properties value dynamically.Learn more about Visual Studio for Mac, the Integrated Development Environment (IDE) for macOS.A short one today to talk about theming on our beloved Xamarin.Forms platform. This document outlines key guidelines to realizing theseĪdvantages for utility and productivity applications. Mobile platforms, reduce your time to market, leverage existing talent, meetĬustomer demand for mobile access, and reduce cross-platformĬomplexity. Building cross-platform applicationsīy choosing Xamarin and keeping a few things in mind when you design andĭevelop your mobile applications, you can realize tremendous code sharing across For developers wishing to just jump right in and start building, this guide can be skipped and read later for a more complete understanding of mobile development. This article discusses the software development lifecycle with respect to mobile applications, and discusses some of the considerations required when building mobile projects. This document explains how Xamarin works at a high-level and links through to the getting-started guides for Xamarin.Forms, Android, and iOS. To learn more about how Xamarin works, and how to approach mobile app development projects, If you'd like to build an app using native UI technologies (like Android XML or Xcode Storyboards), try one of these platform-specific guides:
