是的,并且你可以通过使用<代码>Frame和 >:

<ContentPage ...>
    <ContentPage.Resources>
        <Style x:Key="IndicatorFrameStyle"
           TargetType="Frame">
            <Setter Property="VisualStateManager.VisualStateGroups">
                <VisualStateGroupList>
                    <VisualStateGroup x:Name="CommonStates">
                        <VisualState x:Name="Normal">
                            <VisualState.Setters>
                                <Setter Property="BackgroundColor"
                                    Value="LightGray" />
                            </VisualState.Setters>
                        </VisualState>
                        <VisualState x:Name="Selected">
                            <VisualState.Setters>
                                <Setter Property="BackgroundColor"
                                    Value="#FF000F" />
                                <Setter Property="WidthRequest"
                                    Value="45" />
                            </VisualState.Setters>
                        </VisualState>
                    </VisualStateGroup>
                </VisualStateGroupList>
            </Setter>
        </Style>
    </ContentPage.Resources>
    <StackLayout Margin="10">
        ...
        <IndicatorView x:Name="indicatorView"
                   Margin="0,0,0,40"
                   IndicatorColor="Transparent"
                   SelectedIndicatorColor="Transparent"
                   HorizontalOptions="Center">
            <IndicatorView.IndicatorTemplate>
                <DataTemplate>
                    <Frame Margin="10"
                       CornerRadius="50"
                       HeightRequest="20"
                       WidthRequest="20"
                       Style="{StaticResource IndicatorFrameStyle}"/>
                </DataTemplate>
            </IndicatorView.IndicatorTemplate>
        </IndicatorView>
    </StackLayout>
</ContentPage>

这里是effect。

<>Update>

最好使用<代码>Border。在Fileme docs中,Xamarin有弗拉米。表格存在。 NET MAUI 帮助正在从Xamarin迁移的用户。表格:NET MAUI。如果你重新建造一座新楼。 NET MAUI建议使用边界。同样,“BoxView isn t”建议,与边境完全相同。虽然盒式电文可以浏览简单的图表,但更好的替代办法是使用NET MAUI Shapes或NET MAUI图表。

<ContentPage ...>
    <ContentPage.Resources>
        <Style x:Key="IndicatorBorderStyle"
           TargetType="Border">
            <Setter Property="VisualStateManager.VisualStateGroups">
                ...
            </Setter>
        </Style>
    </ContentPage.Resources>
    <StackLayout Margin="10">
        ...
        <IndicatorView x:Name="indicatorView"
                   Margin="0,0,0,40"
                   IndicatorColor="Transparent"
                   SelectedIndicatorColor="Transparent"
                   HorizontalOptions="Center">
            <IndicatorView.IndicatorTemplate>
                <DataTemplate>
                    <Border Margin="10"
                       StrokeShape="RoundRectangle 50"
                       HeightRequest="20"
                       WidthRequest="20"
                       Style="{StaticResource IndicatorBorderStyle}"/>
                </DataTemplate>
            </IndicatorView.IndicatorTemplate>
        </IndicatorView>
    </StackLayout>
</ContentPage>
