Add Support for `StatusBarBehavior` in Android Modal Page by TheCodeTraveler · Pull Request #3123 · CommunityToolkit/Maui

TheCodeTraveler · 2026-02-27T20:28:03Z

Description of Change

This PR updates StatusBar.android.cs to get the current window, checking to see if a Modal Page is being displayed.

Because MAUI uses a Dialog with its own Window, not the Activity's Window for modal pages, Platform.CurrentActivity?.Window gives the wrong window when a modal is displayed. This PR updates the extension method GetCurrentWindow() to check for a DialogFragment (aka a .NET MAUI Modal Page on Android) and returns the DialogFragment's Window.

Pull request overview

This PR aims to make StatusBarBehavior work correctly on Android modal pages by resolving and targeting the active modal Window (DialogFragment window) instead of always using the hosting Activity’s window. It also simplifies a shared property-changed helper and refreshes the sample UI layout for StatusBar/NavigationBar pages.

Changes:

Update Android StatusBar implementation to resolve the “current window” (including modal DialogFragment windows) before applying color/style.
Replace multiple IsOneOf overloads with a single variadic helper in PropertyChangedEventArgsExtensions.
Update sample view model defaults and tweak sample XAML layout for StatusBar/NavigationBar selection UI.

+			window.SetFlags(WindowManagerFlags.DrawsSystemBarBackgrounds, WindowManagerFlags.DrawsSystemBarBackgrounds);
+		}
+
+		WindowCompat.SetDecorFitsSystemWindows(window, !isColorTransparent);


This method is deprecated on Android API 36. It is highly recommended that we add a check and only use it on an OS using a lower API.

+		bool isColorTransparent = platformColor == PlatformColor.Transparent;
+		if (isColorTransparent)
+		{
+			window.ClearFlags(WindowManagerFlags.DrawsSystemBarBackgrounds);


I don't know any other way to deal with issue of status bar transparency but settings and clearing flags can and will interfere with developers attempts to set or use full screen and in a test app I had to remove all the settings and clearing of flags to have my app do what I wanted. I removed it throughout the toolkit where I found it in statusbar.

I am not sure what we should do here. This is more a comment about the current state of the behavior of hiding/showing status bar is a complicated mess atm and depending on API level settings these options will have completely different behavior on each API.

I do not advocate ripping out the flags I am simply stating all of my use cases do require it. It would have significant impact on all API below 36 so I am not suggesting we do that. Just maybe add checks and block the changes for android 36?

It might be a good idea to add full-screen mode to CommunityToolkit.Maui so it doesn't interfere with the color change. We could also use an IsVisible boolean on the status bar and navigation bar.

@IgrisModz sure! What specifically do we need to add?

Do you have any links to documentation you could share?

The issue I was having was unrelated to flags and I am happy to now approve this pr. I found out the issue was with my app and has nothing to do with @TheCodeTraveler code. It was all me. Anyways these changes do fix the issues they raised and I will be very happy to see the fixes live.

Hi @TheCodeTraveler ,
google have deprecated the Statusbar and Navigationbar coloring, because we have to use EdeToEdge with correct insets. Adding an overlay view looks like a hack. 🤣
