Windows Phone 7两个页面动画跳转

两个页面之间创建带有动画的过渡效果基本步骤：
①截获当前任何表明用户正在离开当前页面的操作
②启动一个动画故事板来隐藏当前页面
③导航到下一个页面
④截获新页面的导航
⑤启动一个动画故事板来显示新页面
 
首先新建一个windows phone的应用程序
mainpage.xaml里面的动画效果代码：
 1 <phone:phoneapplicationpage.resources>
 2         <storyboard x:name="hidepage">
 3             <doubleanimationusingkeyframes
 4                 storyboard.targetproperty="(uielement.rendertransform).(compositetransform.translatex)"
 5                 storyboard.targetname="phoneapplicationpage">
 6                 <easingdoublekeyframe keytime="0" value="0"/>
 7                 <easingdoublekeyframe keytime="0:0:2" value="-480"/>
 8             </doubleanimationusingkeyframes>
 9             <doubleanimationusingkeyframes
10                 storyboard.targetproperty="(uielement.rendertransform).(compositetransform.translatey)"
11                 storyboard.targetname="phoneapplicationpage">
12                 <easingdoublekeyframe keytime="0" value="0"/>
13                 <easingdoublekeyframe keytime="0:0:2" value="-800"/>
14             </doubleanimationusingkeyframes>
15         </storyboard>
16     </phone:phoneapplicationpage.resources>
17     <phone:phoneapplicationpage.rendertransform>
18         <compositetransform/>
19     </phone:phoneapplicationpage.rendertransform>

然后拖一个button控件，并触发click事件，导航到page1.xaml
1 private void button1_click(object sender, routedeventargs e)
2         {
3             this.navigationservice.navigate(new uri("/page1.xaml", urikind.relative));
4         }

在mainpage.xaml.cs里面重写onnavigatingfrom方法：
 1 protected override void onnavigatingfrom(system.windows.navigation.navigatingcanceleventargs e)
 2         {
 3             base.onnavigatingfrom(e);
 4
 5             if (uritonavigateto == null)
 6             {
 7                 e.cancel = true;
 8                 uritonavigateto = e.uri;
 9                 this.hidepage.begin();
10                 this.hidepage.completed += new eventhandler(hidepage_completed);
11             }
12             else
13             {
14                 uritonavigateto = null;
15             }
16         }
17
18         private void hidepage_completed(object sender, eventargs e)
19         {
20             this.navigationservice.navigate(new uri("/page1.xaml", urikind.relative));
21         }

接着新建一个windowsphone页面page1.xaml
page1.xaml的动画效果代码如下：
 1 <phone:phoneapplicationpage.resources>
 2         <storyboard x:name="displaypage">
 3             <doubleanimationusingkeyframes
 4                 storyboard.targetproperty="(uielement.rendertransform).(compositetransform.scalex)"
 5                 storyboard.targetname="phoneapplicationpage">
 6                 <easingdoublekeyframe keytime="0" value="0"/>
 7                 <easingdoublekeyframe keytime="0:0:3" value="1"/>
 8             </doubleanimationusingkeyframes>
 9             <doubleanimationusingkeyframes
10                 storyboard.targetproperty="(uielement.rendertransform).(compositetransform.scaley)"
11                 storyboard.targetname="phoneapplicationpage">
12                 <easingdoublekeyframe keytime="0" value="0"/>
13                 <easingdoublekeyframe keytime="0:0:2" value="1"/>
14             </doubleanimationusingkeyframes>
15             <doubleanimationusingkeyframes
16                 storyboard.targetproperty="(uielement.rendertransform).(compositetransform.rotation)"
17                 storyboard.targetname="phoneapplicationpage">
18                 <easingdoublekeyframe keytime="0" value="-720"/>
19                 <easingdoublekeyframe keytime="0:0:2" value="0"/>
20             </doubleanimationusingkeyframes>
21         </storyboard>
22     </phone:phoneapplicationpage.resources>
23     <phone:phoneapplicationpage.rendertransform>
24         <compositetransform centerx="240" centery="400"/>
25     </phone:phoneapplicationpage.rendertransform>

然后在page1.xaml.cs的初始化函数里写如下代码：
1 public page1()
2         {
3             initializecomponent();
4
5             this.displaypage.begin();
6         }

就这样，一个最基本的两个页面动画跳转效果就做好了
