c# - 在播放器框架元素 WP8.1 中自定义播放/暂停按钮

Question

我的播放器框架(XAML WINRT、Windows Phone 8.1 应用程序)上有一个小的自定义问题，我正在尝试删除播放/暂停和全屏按钮周围的圆圈:

我希望它们看起来更像这样:

我可以访问播放/暂停按钮的默认 XAML:

但是 Blend 不允许我创建元素的副本以便我可以对其进行自定义:

你知道我能做些什么来解决这个问题吗？或者是否有另一种解决方案来删除播放/暂停周围的圆圈？

编辑:

为了获得第二张图片，我对全屏按钮进行了 Photoshop 处理，以显示我想要的内容。

我已经找到了解决方法来为 AppBarButton 找到样式“TransportBarButtonStyle”，而 Blend & Visual studio 不想给我它。

您可以在播放器框架的 codeplex 网站上找到它: https://playerframework.codeplex.com/SourceControl/latest#Universal.Xaml.Core/Themes/Classic.xaml你需要寻找:

<Style x:Key="TransportBarButtonStyle" TargetType="AppBarButton">

在查看 codeplex 之后，https://playerframework.codeplex.com/SourceControl/latest#Universal.Xaml.Core/Themes/Classic.xaml

我创建了一个新样式，它以 AppBarButton 为目标，它的边框周围没有任何圆圈:

<Style x:Key="CircleLessTransportBarButtonStyle" TargetType="AppBarButton">
    <Setter Property="Foreground" Value="{ThemeResource AppBarItemForegroundThemeBrush}"/>
    <Setter Property="VerticalAlignment" Value="Center"/>
    <Setter Property="HorizontalAlignment" Value="Center"/>
    <Setter Property="Padding" Value="0"/>
    <Setter Property="IsCompact" Value="True"/>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="AppBarButton">
                <Grid x:Name="RootGrid" Background="Transparent">
