在播放器框架元素 WP8.1 中自定义 Play/Pause 个按钮

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，我正在尝试删除围绕 Play/Pause 和全屏按钮：

我希望他们看起来更像这样：

我可以访问 Play/Pause 按钮的默认值 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 play/pause 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，可以为 AppBarButton 找到 Blend & Visual studio 不想给我的样式 "TransportBarButtonStyle"。

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">

看完codeplex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">
