UWP - 语言更改 [英] UWP - Change of Languages

问题描述

我正在尝试更改 UWP 应用程序中的语言，以便我的 x:uid 对象相关和我的基于 ResourceLoader 的对象会更改.我正在按照其他问答中的建议使用:

I am trying to change a language at a UWP app so that the my x:uid objects related and my ResourceLoader based objects would change. I am using, as recommended at other Q&A :

ApplicationLanguages.PrimaryLanguageOverride = newLanguage;
Windows.ApplicationModel.Resources.Core.ResourceContext.GetForCurrentView().Reset();
Windows.ApplicationModel.Resources.Core.ResourceContext.GetForViewIndependentUse().Reset();
Frame.Navigate(this.GetType());

但是，由 ResourceLoader 直接控制的所有内容都已更改，并且在 xaml 中使用 x:uid 创建的内容不会更改.如果我再次更改语言，x:uid 将更改为以前的语言，其余为新选择的语言.

However, everything that is controlled directly by the ResourceLoader is changed and whatever is created at the xaml with x:uid don't. If I change the language again then, x:uid changes to the previous language and the rest is at the new selected language.

我认为可能有一些与线程行为相关的原因有两个.首先，修复它的建议是在导航之前延迟线程.其次，我在虚拟机和物理机上有不同的行为(这个错误显然发生在物理机上).

I think that there might be something that is related to thread behavior for two reasons. First, a suggestion to fix it, that works, is to delay the thread before the navigation. Second, I have different behavior at virtual and physical machines (this bug happens at the physical machine obviously).

我非常感谢能够提供不基于延迟线程的良好功能的解决方案或解释.

推荐答案

我已经报告了这个问题，目前有一个解决方法是在调用 Reset 方法后使用延迟.您可以参考以下代码.

I have reported this issue, and currently there is a workaround that use delay after Reset method invoked. You could refer the following code.

using System.Threading.Tasks;

static bool m_bFirstLanguageChangeNavigation = true;


async private void Show_Click(object sender, RoutedEventArgs e)
{
    var context = ResourceContext.GetForCurrentView();
    var selectedLanguage = MyComboBox.SelectedValue;
    var lang = new List<string>();
    lang.Add(selectedLanguage.ToString());
    ApplicationLanguages.PrimaryLanguageOverride = selectedLanguage.ToString();
    ResourceContext.GetForCurrentView().Reset();
    ResourceContext.GetForViewIndependentUse().Reset();


    //added to work the first time
   if (m_bFirstLanguageChangeNavigation)
    {
       m_bFirstLanguageChangeNavigation = false;
       await Task.Delay(100);
    }


    Frame.Navigate(this.GetType());               
}
