TabbedPage page swiping on Android

This .NET Multi-platform App UI (.NET MAUI) Android platform-specific is used to enable swiping with a horizontal finger gesture between pages in a TabbedPage. It's consumed in XAML by setting the TabbedPage.IsSwipePagingEnabled attached property to a boolean value:

<TabbedPage ...
            xmlns:android="clr-namespace:Microsoft.Maui.Controls.PlatformConfiguration.AndroidSpecific;assembly=Microsoft.Maui.Controls"
            android:TabbedPage.OffscreenPageLimit="2"
            android:TabbedPage.IsSwipePagingEnabled="true">
    ...
</TabbedPage>

Alternatively, it can be consumed from C# using the fluent API:

using Microsoft.Maui.Controls.PlatformConfiguration.AndroidSpecific;
...

On<Microsoft.Maui.Controls.PlatformConfiguration.Android>()
    .SetOffscreenPageLimit(2)
    .SetIsSwipePagingEnabled(true);

Note

This platform-specific has no effect on tabs in Shell-based apps.

The TabbedPage.On<Microsoft.Maui.Controls.PlatformConfiguration.Android> method specifies that this platform-specific will only run on Android. The TabbedPage.SetIsSwipePagingEnabled method, in the Microsoft.Maui.Controls.PlatformConfiguration.AndroidSpecific namespace, is used to enable swiping between pages in a TabbedPage. In addition, the TabbedPage class in the Microsoft.Maui.Controls.PlatformConfiguration.AndroidSpecific namespace also has a EnableSwipePaging method that enables this platform-specific, and a DisableSwipePaging method that disables this platform-specific. The TabbedPage.OffscreenPageLimit attached property, and SetOffscreenPageLimit method, are used to set the number of pages that should be retained in an idle state on either side of the current page.

The result is that swipe paging through the pages displayed by a TabbedPage is enabled:
