在 xamarin android 应用程序中更改显示语言 [英] Change display language within an xamarin android app

问题描述

如何更改应用内的显示语言?我希望不同文化的用户可以使用一台扫描仪工作，而不会改变设备的全球文化.

How can I change the display language within an app? I want that users with different cultures can work with one scanner without changing the global culture of the device.

我有一个带有点击事件的语言按钮，我在其中调用了一个方法:

I have a laguage button with a click event in wich I call a method:

public void SetLocale(string language = "")
{
    Locale locale = String.IsNullOrEmpty(language)
                               ? new Locale("de-DE")
                               : new Locale(language);
    Locale.Default = locale;
    var config = new global::Android.Content.Res.Configuration();
    config.Locale = locale;
    var context = global::Android.App.Application.Context;
    context.Resources.UpdateConfiguration(config, context.Resources.DisplayMetrics);
}

但不幸的是，当我按下按钮时没有任何反应.

But unfortunately nothing happens when I press the button.

点击事件为:

_btnen.Click += delegate
{
    SetLocale("en-GB");
};

推荐答案

What can work for You，如果上下文可以被遗忘(所有属性值都可以丢失)，你可以只强制Activity 重绘自身.

What can work for You, if the context can be forgotten (all property values can be lost), You can just force the Activity to redraw itself.

btn.Click += delegate
{
    SetLocale("en-GB");

    this.Recreate(); //this line
}
