Xamarin.Forms：如何使用独立于设备语言的本地化 [英] Xamarin.Forms : How to use localization independent of device language

问题描述

我正在使用Visual Studio 2013 CE开发一个Xamarin.Forms应用程序（可移植类库项目）。首先我关注iOS版本。

I am developing a Xamarin.Forms app (portable class library project) with Visual Studio 2013 CE. First I'm focusing the iOS version.

现在我正在考虑如何使应用程序多语言化。
我刚刚阅读了关于它的官方Xamarin文档，但我意识到这个解决方案只采用目标设备的系统语言。

Now I'm thinking about how to make the app multilingual. I just read the offical Xamarin documentation about it but i realized that this solution only takes the system language of the target device.

在便携式类库中我有一个包含三种语言的Resources文件夹：德语（默认），英语和法语。

In the portable class library I have a Resources folder with three languages: German (default), English and French.

Resource.resx
Resource.en-US.resx
Resource.fr-FR.resx
Resource.Designer.cs

现在我刚刚创建了一个静态设置类，如下所示：

Now i just created a static settings class which looks like this:

public static class Settings
{
    public static Dictionary<String, CultureInfo> Languages = new Dictionary<String, CultureInfo> { { "German", new CultureInfo("de-DE") }, { "English", new CultureInfo("en-US") }, { "French", new CultureInfo("fr-FR") } };

    public static CultureInfo CurrentCulture = Languages["German"];
    public static CultureInfo CurrentUiCulture = Languages["German"];

    public static void ChangeCurrentCultureInfo(CultureInfo cultureInfo)
    {
        Resource.Culture = cultureInfo;
    }
}

现在我的问题是，是否有可能改变文化在应用程序中运行时单击按钮。
也许类似

Now my question is if it's possible to change the culture in the application while runtime with a button click. Maybe something like

Settings.CurrentCulture = Settings.Languages["English"];
Settings.ChangeCurrentCultureInfo(Settings.CurrentCulture);

有人能告诉我这是怎么做到的吗？

Does anyone can tell me how this can be done?

推荐答案

最后我得到了Xamarin支持的答案。
我正在思考的解决方案。在PCL中，我只有静态设置类，它存储不同的 CultureInfo 对象。另外，我定义了一种方法来更改当前文化和资源文件的语言。

Finally i got an answer of the Xamarin support. The solution i was thinking about works. In the PCL i just have the static Settings class which stores the different CultureInfo objects. In addition I defined a method for changing the current culture and the language of the resources file.

public static void ChangeCurrentCultureInfo(CultureInfo cultureInfo)
{
    CurrentCulture = cultureInfo;
    Resource.Culture = CurrentCulture;
}

在中设置默认语言非常重要初始化主页面之前的App（）构造函数。现在我得到了一个包含所有支持语言的列表视图，其中一个调用事件调用 ChangeCurrentCultureInfo 方法。

It was important to set the default language in the App() constructor before I initialize the main page. Now i got a listview with all supported languages with one tapped event which calls the ChangeCurrentCultureInfo method.

尽管如此我想要感谢 Andy Hopper 提供他的解决方案！

Nevertheless i want to thank Andy Hopper for providing his solution!
