-->Xamarin.Forms applications can respond to style changes dynamically at runtime by using the DynamicResource
markup extension. This markup extension is similar to the StaticResource
markup extension, in that both use a dictionary key to fetch a value from a ResourceDictionary
. However, while the StaticResource
markup extension performs a single dictionary lookup, the DynamicResource
markup extension maintains a link to the dictionary key. Therefore, if the value associated with the key is replaced, the change is applied to the VisualElement
. This enables runtime theming to be implemented in Xamarin.Forms applications.
The process for implementing runtime theming in a Xamarin.Forms application is as follows:
- Define the resources for each theme in a
ResourceDictionary
. - Consume theme resources in the application, using the
DynamicResource
markup extension. - Set a default theme in the application's App.xaml file.
- Add code to load a theme at runtime.
Important
Use the StaticResource
markup extension if you don't need to change the app theme at runtime.
The following screenshots show themed pages, with the iOS application using a light theme and the Android application using a dark theme:
Note
Changing a theme at runtime requires the use of XAML styles, and is not currently possible using CSS.
Define themes
A theme is defined as a collection of resource objects stored in a ResourceDictionary
.
The following example shows the LightTheme
from the sample application:
The following example shows the DarkTheme
from the sample application:
Each ResourceDictionary
contains Color
resources that define their respective themes, with each ResourceDictionary
using identical key values. For more information about resource dictionaries, see Resource Dictionaries.
Important
A code behind file is required for each ResourceDictionary
, which calls the InitializeComponent
method. This is necessary so that a CLR object representing the chosen theme can be created at runtime.
Set a default theme
An application requires a default theme, so that controls have values for the resources they consume. A default theme can be set by merging the theme's ResourceDictionary
into the application-level ResourceDictionary
that's defined in App.xaml:

For more information about merging resource dictionaries, see Merged resource dictionaries.
Consume theme resources
When an application wants to consume a resource that's stored in a ResourceDictionary
that represents a theme, it should do so with the DynamicResource
markup extension. This ensures that if a different theme is selected at runtime, the values from the new theme will be applied.
The following example shows three styles from the sample application that can be applied to Label
objects:
These styles are defined in the application-level resource dictionary, so that they can be consumed by multiple pages. Each style consumes theme resources with the DynamicResource
markup extension.
These styles are then consumed by pages:

When a theme resource is consumed directly, it should be consumed with the DynamicResource
markup extension. However, when a style that uses the DynamicResource
markup extension is consumed, it should be consumed with the StaticResource
markup extension.
For more information about styling, see Styling Xamarin.Forms Apps using XAML Styles. For more information about the DynamicResource
markup extension, see Dynamic Styles in Xamarin.Forms.
Load a theme at runtime
When a theme is selected at runtime, the application should:
- Remove the current theme from the application. This is achieved by clearing the
MergedDictionaries
property of the application-levelResourceDictionary
. - Load the selected theme. This is achieved by adding an instance of the selected theme to the
MergedDictionaries
property of the application-levelResourceDictionary
.
Any VisualElement
objects that set properties with the DynamicResource
markup extension will then apply the new theme values. This occurs because the DynamicResource
markup extension maintains a link to dictionary keys. Therefore, when the values associated with keys are replaced, the changes are applied to the VisualElement
objects.
In the sample application, a theme is selected via a modal page that contains a Picker
. The following code shows the OnPickerSelectionChanged
method, which is executed when the selected theme changes:
