Question

我想在Xamarin Forms - UWP中单击ListView项目时更改突出显示的颜色。在android我设置样式来解决这个问题。async saveFavorite() { // loadFavorite() here, // make sure you've got data "your_new_JSON_data" which has been converted into object, then maybe: "your_new_JSON_data.push({NEW_OBJ})"; // after that, SAVE NEW DATA now: try { await AsyncStorage.setItem("@PROJECT_NAME:your_favorite_array", JSON.stringify(your_new_JSON_data)); // same here, if you use flux or redux here, you can save the new data here: // FavoriteActionCreators.set_favorite(your_new_JSON_data); } catch (error) { console.log('AsyncStorage error: ' + error.message); } }我如何实现同样的目标是UWP。添加的图片：http://imgur.com/a/pFlNi

Answer 1

导航到您的UWP项目，打开您的App.xaml，并放置以下内容：

<Application.Resources>
    <ResourceDictionary>
        <ResourceDictionary.ThemeDictionaries>
        <ResourceDictionary x:Key="Default">

<!--Your accent color-->
<Color x:Key="SystemAccentColor">#FF055ADA</Color>                

<SolidColorBrush x:Key="SystemControlHighlightAltListAccentHighBrush" Color="{ThemeResource SystemAccentColor}" Opacity="0.9" />
<SolidColorBrush x:Key="SystemControlHighlightAltListAccentLowBrush" Color="ThemeResource SystemAccentColor}" Opacity="0.6" />
<SolidColorBrush x:Key="SystemControlHighlightAltListAccentMediumBrush" Color="{ThemeResource SystemAccentColor}" Opacity="0.8" />
<SolidColorBrush x:Key="SystemControlHighlightListAccentHighBrush" Color="{ThemeResource SystemAccentColor}" Opacity="0.9" />
<SolidColorBrush x:Key="SystemControlHighlightListAccentLowBrush" Color="{ThemeResource SystemAccentColor}" Opacity="0.6" />
<SolidColorBrush x:Key="SystemControlHighlightListAccentMediumBrush" Color="{ThemeResource SystemAccentColor}" Opacity="0.8" />

    </ResourceDictionary>
  </ResourceDictionary.ThemeDictionaries>
 </ResourceDictionary>
</Application.Resources>

这应该通过覆盖默认的UWP ResourceDictionary.ThemeDictionaries

来工作
