xamarin - 如何将 LinearGradientBrush 设置为 ContentPages 的背景？

Question

我怎样才能LinearGradientBrush像ContentPage.BackgroundinApp.xaml一样添加ResourceDictionary？我的代码粘贴在下面：

<LinearGradientBrush EndPoint="0,1">
    <GradientStop Color="LightBlue"
                  Offset="0.1" />
    <GradientStop Color="DarkBlue"
                  Offset="1.0" />
</LinearGradientBrush>

由于 LinearGradientBrush 是一个预览概念，不要忘记在您的App.xaml.cs.

Device.SetFlags(new string[] {"Brush_Experimental" });

并将以下添加到App.xaml：

<Application.Resources>
    <ResourceDictionary>
        <Style  TargetType="ContentPage" ApplyToDerivedTypes="True">
            <Setter Property="Background">
                    <LinearGradientBrush EndPoint="0,1">
                        <GradientStop Color="LightBlue"
              Offset="0.1" />
                        <GradientStop Color="DarkBlue"
              Offset="1.0" />
                    </LinearGradientBrush>
            </Setter>
        </Style>
    </ResourceDictionary>
</Application.Resources>
