.Net MAUI Android App: Change Navigation and Status Bar colors at Splash screen moment

I'm trying to change Navigation Bar and Status Bar background color in my .Net MAUI Android App.

I found how to do that when the app has initialized an loaded (Status Bar: Using MauiCommunityToolkit StatusBarBehavior StatusBarColor feature. Navigation Bar: Using Window.SetNavigationBarColor).

But I have not found how to do that when the app starts and shows the Splash Screen. I need black background color for both, Status and Navigation bar but when the App starts, NavBar is white and Status Bar is Purple (default .Net MAUI color). I attached an image of how it looks when starts.

I tried changing the Primary Color in the Resources/colors.xml, and it didn't work.

My App is a MAUI Single project template (Android and iOS).

Thanks in advance for taking a look at this issue.enter image description here

UPDATE: I was able to change just Status Bar, changing defautl colorPrimaryDark value in Platforms/Android/Resources/colors.xml enter image description here

But still looking at how to change Navigation Bar color. enter image description here

Solution

  • You can create a new .xml file and then put the style in or add the style to colors.xml directly:

    <resources>
    <color name="colorPrimary">#512BD4</color>
    <color name="colorPrimaryDark">#2B0B98</color>
    <color name="colorAccent">#2B0B98</color>
    
    <style name="SplashTheme" parent="@style/Maui.SplashTheme">
        <item name="android:statusBarColor">@android:color/black</item>
        <item name="android:navigationBarColor">@android:color/black</item>
    </style>
</resources>

    In the MainActivity.cs file (Platforms/Android):

    [Activity(
    //Theme = "@style/Maui.SplashTheme",
    Theme = "@style/SplashTheme",
    MainLauncher = true, ConfigurationChanges = ConfigChanges.ScreenSize | ConfigChanges.Orientation | ConfigChanges.UiMode | ConfigChanges.ScreenLayout | ConfigChanges.SmallestScreenSize)]
public class MainActivity : MauiAppCompatActivity

    It works well and can achieve your need.
