Question

所以，我正在创建通用的Windows手机应用程序。我正在尝试更改数据库标题面板中单击项目的颜色。我已使用以下语法在Windows Phone项目中添加了Styling.axml文件：

            </Setter.Value>
        </Setter>
    </Style>
</ResourceDictionary>

在共享项目的App.xaml文件中，我正在尝试添加这段代码

<ResourceDictionary x:Key="Dictionary">
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="Styling.xaml" />
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>

但我收到错误＆＃34; En找到资源字典时发生错误＆＃34; Styling.axml＆＃34;。

Answer 1

您需要为通用应用程序引用这样的字典（假设字典在共享项目中）：

<ResourceDictionary Source="ms-appx:///MyUniversaldResourceDictionary.xaml"/>

如果您想了解更多细节，我最近在博客上写了这篇文章： Accessing Resources in a Universal App

Answer 2

所以我放弃了这种方法，这就是我在代码中解决它的方法：在.xaml文件中，在Pivot标记中添加此属性：SelectionChanged =＆＃34; MyPivot_SelectionChanged＆＃34;

而不是代码：

 private void MyPivot_SelectionChanged(object sender,    SelectionChangedEventArgs e)
        {
            foreach (PivotItem pivotItem in MyPivot.Items)
            {
                if (pivotItem == MyPivot.Items[MyPivot.SelectedIndex])
                {
                    //selected
                   ((TextBlock)pivotItem.Header).Foreground = new SolidColorBrush(Windows.UI.Color.FromArgb(255,31, 93, 184));
                }
                else
                {
                     // not selected
                    ((TextBlock)pivotItem.Header).Foreground = new SolidColorBrush(Windows.UI.Color.FromArgb(255,109, 162, 240 ));
                 }
             }
         }
