TabbedPage toolbar placement on Android

  • Artikel

This .NET Multi-platform App UI (.NET MAUI) Android platform-specific is used to set the placement of the toolbar on a TabbedPage. It's consumed in XAML by setting the TabbedPage.ToolbarPlacement attached property to a value of the ToolbarPlacement enumeration:

<TabbedPage ...
            xmlns:android="clr-namespace:Microsoft.Maui.Controls.PlatformConfiguration.AndroidSpecific;assembly=Microsoft.Maui.Controls"
            android:TabbedPage.ToolbarPlacement="Bottom">
    ...
</TabbedPage>

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

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

On<Microsoft.Maui.Controls.PlatformConfiguration.Android>().SetToolbarPlacement(ToolbarPlacement.Bottom);

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.SetToolbarPlacement method, in the Microsoft.Maui.Controls.PlatformConfiguration.AndroidSpecific namespace, is used to set the toolbar placement on a TabbedPage, with the ToolbarPlacement enumeration providing the following values:

  • Default – indicates that the toolbar is placed at the default location on the page. This is the top of the page on phones, and the bottom of the page on other device idioms.
  • Top – indicates that the toolbar is placed at the top of the page.
  • Bottom – indicates that the toolbar is placed at the bottom of the page.

Note

The GetToolbarPlacement method can be used to retrieve the placement of the TabbedPage toolbar.

The result is that the toolbar placement can be set on a TabbedPage:
