如何在Xaml文本中有一个电子邮件链接

本文关键字：有一个 电子邮件 链接 文本 Xaml | 更新日期: 2023-09-27 18:01:32

我在Windows phone 8应用程序中有一些大文本，我希望里面有电子邮件链接，类似于mailto功能。下面是部分代码:

<phone:PivotItem Header="μέλη ΔΕΠ">
    <ScrollViewer>
        <StackPanel>
            <TextBlock TextWrapping="Wrap">                     
            <Run Text="John Doe"/>
            <LineBreak/>
            <Run Text="503 (Building DS 126)"/>
            <LineBreak/>
            <Run Text="tel.:  +30 210-1234567"/>
            <LineBreak/>
            <Run Text="e-mail:  johndoe@uni.gr"/>
            </TextBlock>
        </StackPanel>
    </ScrollViewer>
</phone:PivotItem>

我希望"e-mail: johndoe@uni.gr"可以点击并打开手机上的邮件应用程序。在我的代码中有很多这样的情况，电子邮件的文本要大得多，这就是我使用<TextBlock><Run Text=".."/><LineBreak/>...格式的原因。

现在我知道我不能在<Run Text=".."/>中使用超链接按钮，所以有什么建议吗?

如何在Xaml文本中有一个电子邮件链接

HyperlinkButton是很好的，如果你想在你的UI超链接，但如果你想一个超链接嵌入到文本运行，你应该使用RichTextBox与 hyperlink :

<RichTextBox TextWrapping="Wrap">
    <Paragraph>
        <Run Text="John Doe" />
        <LineBreak />
        <Run Text="503 (Building DS 126)" />
        <LineBreak />
        <Run Text="tel.:  +30 210-1234567" />
        <LineBreak />
        <Hyperlink Click="Hyperlink_OnClick">e-mail:   johndoe@uni.gr</Hyperlink>
    </Paragraph>
</RichTextBox>

然后使用Julien回答中的handler:

    private void Hyperlink_OnClick(object sender, RoutedEventArgs e) {
        EmailComposeTask emailComposeTask = new EmailComposeTask();
        emailComposeTask.Subject = "message subject";
        emailComposeTask.Body = "message body";
        emailComposeTask.To = "johndoe@uni.gr";
        emailComposeTask.Show();
    }

祝你好运!

您还可以这样做:

重载MapUri()，因为它是为一个应用程序的URI-Associations所做的，再也不用担心处理任何点击事件了。

XAML: 

<Hyperlink NavigateUri="tel:0800-555-1234'}">call 0800-555-1234</Hyperlink>
<Hyperlink NavigateUri="mailto:you@your-domain.com'}">e-Mail you@your-domain.com</Hyperlink>
c# App.xaml.cs 

 private void InitializePhoneApplication() {

…

 //get ready for URI association
 RootFrame.UriMapper = new AssociationUriMapper();

}

c# 

class AssociateioniMapper : UriMapperBase
{
public override Uri MapUri(Uri uri)
{
    tempUri = System.Net.HttpUtility.UrlDecode(uri.ToString());
    Uri retUri = uri;
    //handle known uri schemes
    if (uriUsesKnownScheme(uri))
    { 
        Debug.WriteLine("Known Uri scheme: " + uri.Scheme);
        NavigateConsideringKnownScheme(uri);
        retUri = null;
    }
}
private bool uriUsesKnownScheme(Uri uri)
{
        try
        {
            switch (uri.Scheme)
            {
                case "http":
                case "https":
                case "mailto":
                case "tel":
                    return true;
                default:
                    return false;
            }
        }
        catch (Exception)
        {
            //uri does not have a scheme
            return false;
        }
} 
private void NavigateConsideringKnownScheme(Uri uri)
    {
        try
        {
            switch (uri.Scheme)
            {
                case schemeHttp:
                case schemeHttps:
                    //open URI in IE
                    WebBrowserTask webBrowserTask = new WebBrowserTask();
                    webBrowserTask.Uri = uri;
                    webBrowserTask.Show();
                    break;
                case schemeMailto:
                    //initiate eMail task
                    if (! string.IsNullOrWhiteSpace(uri.Query))
                        handleMailtoUrl_Query(uri.Query);
                    else
                        handleMailtoUrl_To(uri.OriginalString.Replace("mailto:", string.Empty));
                    break;
                case schemeTel:
                    //initiate phonecall task
                    handleTel(uri.PathAndQuery);
                    break;
                default:
                    break;
            }
        }
        catch (Exception ex)
        {
            Debug.WriteLine(ex.Message);
        }
    }   
    private void handleTel(string parameter)
    {
        try
        {
            string p = parameter as string;
            string number = p;
            string displayName = string.Empty;
            number = Regex.Replace(number, "[^+0-9]", "");
            startPhoneCall(number, displayName);
        }
        catch (Exception e)
        {
            throw e;
        }
    }
    private void startPhoneCall(string number, string displayName)
    {
        try
        {
            PhoneCallTask phoneCallTask = new PhoneCallTask();
            phoneCallTask.PhoneNumber = number;
            if (!string.IsNullOrWhiteSpace(displayName))
            {
                phoneCallTask.DisplayName = displayName;
            }
            phoneCallTask.Show();
        }
        catch (Exception e)
        {
            MessageBox.Show(LocalizationHelper.GetString("ContactPhonecallError"));
        }
    }
    private void handleMailtoUrl_Query(string query)
    {
       //handle subject, to, body and other parameters if required
    }
    private void handleMailtoUrl_To(string to)
    {
        try
        {
            EmailComposeTask emailComposeTask = new EmailComposeTask();
            emailComposeTask.To = to;
            emailComposeTask.Show();
        }
        catch (Exception e)
        {
            Debug.WriteLine(e.Message);
        }
    }
}

添加HyperLinkButton:

<HyperlinkButton Name="emailLink" Content="johndoe@uni.gr" Click="EmailLink_Click" />

和在EmailLink_Link中，您可以启动EmailComposeTask (http://msdn.microsoft.com/en-us/library/windowsphone/develop/hh394003(v=vs.105).aspx)

private void EMailLink_Click(object sender, RoutedEventArgs e)
{
  EmailComposeTask emailComposeTask = new EmailComposeTask();
  emailComposeTask.Subject = "message subject";
  emailComposeTask.Body = "message body";
  emailComposeTask.To = emailLink.Content;
  emailComposeTask.Show();
}

更容易:

XAML: 

<HyperlinkButton Content="yourname@yourdomain.com" Click="HyperlinkButton_Click"/>

单击事件处理程序:

private void HyperlinkButton_Click(object sender, RoutedEventArgs e)
{
    Windows.System.Launcher.LaunchUriAsync(new Uri("mailto:yourname@yourdomain.com"));
}

除了打开你的电子邮件应用程序，还有很多你可以用Launcher: http://msdn.microsoft.com/en-us/library/windowsphone/develop/jj662937(v=vs.105).aspx
