How to Set DarkMode for Status Bar Color in Xamarin Forms for Android

If you're developing an Android application using Xamarin Forms, you might want to add the ability to switch between light and dark themes. However, one problem developers frequently encounter is the difficulty in changing the status bar color on the initial page load. This issue can be frustrating, but with the right approach, you can resolve it quickly. In this guide, we will explore how to dynamically change the status bar color depending on the selected theme.

Understanding the Problem

When users toggle between dark and light modes, the expectation is that the app will adapt its appearance accordingly, including the status bar. While Xamarin Forms provides mechanisms for theme management, ensuring that the status bar reflects these changes can sometimes be tricky. Specifically, if you've set up a switching mechanism but the status bar color remains unchanged upon app load, it may be necessary to adjust your code within the Android project.

Steps to Resolve the Status Bar Color Issue

1. Setting the Status Bar Color

To effectively change the status bar color based on the selected theme, you need to utilize the SetStatusBarColor method properly. Below is a refined code snippet that should help:

2. Applying the Status Bar Color at Startup

To ensure the status bar color is set correctly when your app starts, you can invoke your method in the MainActivity.OnCreate method.

Here’s how you can structure it:

3. Listening for Theme Changes

In the code above, we also attach an event listener to App.Current.RequestedThemeChanged. This ensures that whenever the user switches the theme, the status bar color updates dynamically.

Summary

By following the steps outlined above, you can ensure that the status bar color of your Xamarin Forms Android application reflects the current theme. The key points to keep in mind are:

Ensure you call the SetStatusBarColor method in the OnCreate method.

Listen for theme changes to update the status bar accordingly.

Use appropriate colors for dark and light themes.

Implementing these changes not only enhances user experience but also makes your application visually consistent across different themes.

Happy coding!
