Cortana集成失败

Question

我正在制作一个基于Windows8.1演讲的应用程序。我的问题是，当我给Cortana提供它启动我的应用程序的输入时，应用程序会在屏幕上关闭，但是当我在后台运行我的应用程序(最小化应用程序)时，或者当应用程序运行时，Cortana输入法工作得很完美。

我哪里出问题了？下面是我的app.xaml.cs代码，在OnActivatedMethod中：

if (args.Kind == ActivationKind.VoiceCommand)
        {
            VoiceCommandActivatedEventArgs vcArgs = (VoiceCommandActivatedEventArgs)args;

            string voiceCommandName = vcArgs.Result.RulePath.First(); // What command launched the app?

            switch (voiceCommandName) // Run the action specific to the command
            {
                case "comand1": // User said comand1
                    rootFrame.Navigate(typeof(SpeechHandlingPage), vcArgs.Result);
                    break;

                case "comand2": // User said comand2
                    rootFrame.Navigate(typeof(SpeechHandlingPage), vcArgs.Result);
                    break;
                case "comand3": // User said comand3
                    rootFrame.Navigate(typeof(SpeechHandlingPage), vcArgs.Result);
                    break;
                case "comand4":
                    rootFrame.Navigate(typeof(SpeechHandlingPage), vcArgs.Result);
                    break;
            }

在语音处理页面的OnNavigated方法中：

SpeechRecognitionResult vcArgs = e.Parameter as SpeechRecognitionResult;
        RcvdCommand = vcArgs.Text.ToUpper();

        // Check for null!
        string commandMode = vcArgs.SemanticInterpretation.Properties["commandMode"][0];

        if (commandMode == "voice") // Did the user speak or type the command?
        {
            RequestHanding();
            MyTextblock.Text = vcArgs.Text;
            // SpeakText(audioPlayer, String.Format(" app heard you say {0}", RcvdCommand ));

            // HandleNlpCommand(vcArgs);
        }
        else if (commandMode == "text")
        {
            // messageTextBox.Text = string.Format("Working on your request \"{0}\"", RcvdCommand);

            // HandleNlpCommand(vcArgs);
        }

当应用程序没有运行，并且由语音命令激活时，不会调用OnLaunched()方法。因此，您需要调用确保在OnActivated()方法中创建根框架的代码：

  Frame rootFrame = Window.Current.Content as Frame;

  // Do not repeat app initialization when the Window already has content,
  // just ensure that the window is active
  if (rootFrame == null)
  {
    // Create a Frame to act as the navigation context and navigate to the first page
    rootFrame = new Frame();

    // ... restore app state, etc.

    Window.Current.Content = rootFrame;
  }
