uwp Button的动态效果

你应该覆盖Button样式

<Page.Resources>
    <Style TargetType="Button" x:Key="CustomButtonStyle">
        <Setter Property="Background" Value="{ThemeResource SystemControlBackgroundBaseLowBrush}" />
        <Setter Property="Foreground" Value="{ThemeResource SystemControlForegroundBaseHighBrush}"/>
        <Setter Property="BorderBrush" Value="{ThemeResource SystemControlForegroundTransparentBrush}" />
