Windows Phone 7编程学习点滴三——12种启动器和4种选择器

一 启动器

有些启动器,它们无法在模拟器上工作。

快速浏览一下启动器:

EmailComposeTask –允许用户通过邮件账户发送电子邮件。

MarketplaceDetailTask –启动Windows Phone Marketplace,让用户查看某个特定的产品。

MarketplaceHubTask –启动Windows Phone Marketplace,默认情况下允许你显示某一类别的应用程序。

MarketplaceReviewTask –将用户带到Windows Phone Marketplace中当前程序的评论页。

MarketplaceSearchTask –启动Windows Phone Marketplace的搜索结果,此结果来源于用户输入的搜索项(或者是你来制定的)。 MediaPlayerLauncher –启动内置的媒体播放器,并播放你指定的媒体文件。

PhoneCallTask –启动电话程序并显示电话号码和姓名。电话只在用户点击“通话”后才会拨出。

SearchTask – 可以把这个看成是在你的程序中提供Bing搜索功能的途径。

SMSComposeTask –启动信息程序并向用户展示发送信息的功能。你可以指定信息接收人和信息内容,但只能通过用户来发送。

WebBrowserTask –打开网络浏览器,跳转到指定的URL。

二 选择器

需要引用Microsoft.Phone.Tasks名称空间。

选择器,在用户做出选择后需要创建一个事件处理程序。否则,你将无法捕获他们所选的数据。

以下是四种选择器列表:

CameraCaptureTask – 为用户提供在程序中直接拍照的功能。

EmailAddressChooserTask – 在程序中允许用户从联系人里面选择一个邮件地址。

PhoneNumberChooserTask – 在程序中允许用户从联系人里面选择一个电话号码。

PhotoChooserTask – 在程序中允许用户从设备里选择一张照片。

 

(1)EmailAddressChooserTask

1 EmailAddressChooserTask eact = new EmailAddressChooserTask();  
2 eact.Completed += new EventHandler<EmailResult>(eact_Completed);  
3 eact.Show();  
4 //  
5 void eact_Completed(object sender, EmailResult e)  
6 {  
7   EmailBlock.Text = e.Email;  
8 }  

(2)CameraCaptureTask

 1 CameraCaptureTask cct = new CameraCaptureTask();  
 2 cct.Completed += new EventHandler<PhotoResult>(cct_Completed);  
 3 cct.Show();  
 4 //  
 5 void cct_Completed(object sender, PhotoResult e)  
 6 {  
 7   BitmapImage bmp = new BitmapImage();  
 8   bmp.SetSource(e.ChosenPhoto);  
 9   image1.Source = bmp;  
10 }  

(3)PhoneNumberChooserTask

1 PhoneNumberChooserTask pnct = new PhoneNumberChooserTask();  
2 pnct.Completed += new EventHandler<PhoneNumberResult>(pnct_Completed);  
3 pnct.Show();  
4 //  
5 void pnct_Completed(object sender, PhoneNumberResult e)  
6 {  
7   PhoneBlock.Text = e.PhoneNumber;  
8 }  

(4)PhotoChooserTask

 1 PhotoChooserTask pct = new PhotoChooserTask();  
 2 pct.Completed += new EventHandler<PhotoResult>(pct_Completed);  
 3 pct.Show();  
 4 //  
 5 void pct_Completed(object sender, PhotoResult e)  
 6 {  
 7   BitmapImage bmp = new BitmapImage();  
 8   bmp.SetSource(e.ChosenPhoto);  
 9   image2.Source = bmp;  
10 }
