对Xamarin Forms Android特定代码项目进行单元测试 [英] Unit testing a Xamarin Forms Android specific code project

问题描述

我遇到了完成Xamarin.Forms应用程序的问题.

I'm running into an issue where I've done a Xamarin.Forms Application.

当前，我正在尝试对Android服务进行单元测试.

Currently, I'm trying to Unit test an Android Service.

因此，目前这意味着我目前已完成以下操作:

So currently this means I've done the following at this point:

1. 已删除iOS项目的默认Xamarin表单应用程序
2. 在PCL中创建了基本表单
3. 具有在Xamarin.Forms PCL中创建的样式
4. 在Xamarin.Forms.Droid项目中具有基本主题

这样做之后，我创建了Xamarin UITest Android项目

After doing that, I've created Xamarin UITest Android Project

现在，我已经添加了对Xamarin Forms.Droid项目的引用

Now, I've added a reference to the Xamarin Forms.Droid Project

每次启动必须在Android模拟器中运行的单元测试时，它都找不到主题.

Every time I launch the unit test, which has to run in the Android emulator, it fails to find the theme.

位于PCL中的app.xml中

within the app.xml that resides in the PCL

<Application.Resources>
    <!-- Application resource dictionary -->
    <ResourceDictionary>
        <Color x:Key="BackgroundGlobal">#ff333333</Color>
        <Color x:Key="MidGradient">#ff0d0d0d</Color>
        <Color x:Key="BottomGradient">Black</Color>
        <Color x:Key="MenuTextColor">Azure</Color>
        <Style TargetType="ImageCell" x:Key="Clicky">
            <Setter Property="TextColor" Value="{StaticResource  MenuTextColor}"/>
            <Setter Property="DetailColor" Value="Aqua"/>
        </Style>
    </ResourceDictionary>
</Application.Resources>

在Xamarin.Forms.Droid Resource \ Values \ strings.xml中

within the Xamarin.Forms.Droid Resource\Values\strings.xml

    <?xml version="1.0" encoding="utf-8" ?>
    <resources>
        <style name="MainTheme" parent="MainTheme.Base">
        </style>

        <!-- Base theme applied no matter what API -->
        <style name="MainTheme.Base" parent="Theme.AppCompat">
            <!--If you are using revision 22.1 please use just windowNoTitle. Without android:-->
            <item name="windowNoTitle">true</item>
            <!--We will be using the toolbar so no need to show ActionBar-->
            <item name="windowActionBar">false</item>
            <!-- Set theme colors from http://www.google.com/design/spec/style/color.html#color-color-palette-->
            <!-- colorPrimary is used for the default action bar background -->
            <item name="colorPrimary">#2196F3</item>
            <!-- colorPrimaryDark is used for the status bar -->
            <item name="colorPrimaryDark">#1976D2</item>
            <!-- colorAccent is used as the default value for colorControlActivated
     which is used to tint widgets -->
            <item name="colorAccent">#FF4081</item>
            <!-- You can also set colorControlNormal, colorControlActivated
     colorControlHighlight and colorSwitchThumbNormal. -->
            <item name="windowActionModeOverlay">true</item>
            <item name="android:datePickerDialogTheme">@style/AppCompatDialogStyle</item>
       </style>   
       <style name="AppCompatDialogStyle" parent="Theme.AppCompat.Light.Dialog">
            <item name="colorAccent">#FF4081</item>
       </style>
   </resources>

我目前得到以下信息:

Severity    Code    Description Project File    Line    Suppression State Error 
Error: No resource found that matches the given name (at 'theme' with value '@style/MainTheme').    Xamarin.Forms.Droid.Tests   C:\dev\git\example\Xamarin.Forms.Droid.Tests\obj\Debug\android\manifest\AndroidManifest.xml 9   

推荐答案

未找到与给定名称匹配的资源(在主题"处，值为"@ style/MainTheme").

No resource found that matches the given name (at 'theme' with value '@style/MainTheme').

Resource\Values\strings.xml只是为您的应用程序提供带有可选文本样式和格式的文本字符串.可以为您的应用程序提供字符串的三种类型的资源:String，String Array和Quantity Strings(Plurals).

Resource\Values\strings.xml just provides a text string with optional text style and formatting for your application. There are three types of resources that can provide a string for your application: String, String Array and Quantity Strings(Plurals).

您应该将主题样式放在Resource\Values\styles.xml而不是styles.xml中，例如此.

You should put your theme style in Resource\Values\styles.xml instead of styles.xml, like this.

有关Style Resource的更多信息，您可以阅读文档.
