Question

我正在尝试更改页面上单个AppBarButton的颜色

我可以通过在App.xaml中设置这些值来更改它，但它们会在整个应用中发生变化

<SolidColorBrush x:Key="AppBarItemBackgroundThemeBrush" Color="Transparent" />
<SolidColorBrush x:Key="AppBarItemDisabledForegroundThemeBrush" Color="#66000000" />
<SolidColorBrush x:Key="AppBarItemForegroundThemeBrush" Color="#FF3399FF" />
<SolidColorBrush x:Key="AppBarItemPointerOverBackgroundThemeBrush" Color="#3D000000" />
<SolidColorBrush x:Key="AppBarItemPointerOverForegroundThemeBrush" Color="#FF000000" />
<SolidColorBrush x:Key="AppBarItemPressedForegroundThemeBrush" Color="#FFFFFFFF" />

所以尝试设置一个我可以随时使用的特定样式我使用它并更改Foreground和Setter中的VisualState Normal颜色但唯一的事情我看到的是图标周围的环，图标本身缺失，按钮的文本也是如此

<Style x:Key="HeaderButtonStyle" TargetType="ButtonBase">
                <Setter Property="Foreground" Value="White"/>

获得的风格

我还需要改变什么？

Answer 1

ContentPresenter系列缺少＆＃39;内容＆＃39;属性。在两个地方将TargetType从ButtonBase更改为AppBarButton并添加＆＃34; Content =＆＃34; {TemplateBinding Icon}＆＃34;到ContentPresenter属性，然后您应该看到图标。

您的风格与默认的AppBarButton风格完全不同。除非我遗漏了你想要做的事情，否则我建议你复制整个风格： http://msdn.microsoft.com/en-us/library/windows/apps/dn481531.aspx 并使用它。
