wp8.1微信_WP8.1开发教程二: MapControl视图控件和Animation动画实例应用

MapControl对应ArcMap中的数据视图，它封装了Map对象，并提供了额外的属性、方法、事件用于：

管理控件的外观、显示属性和地图属性；
添加并管理控件中的数据层；
装载Map文档（.mxd）到控件中
从其它应用程序拖放数据到控件中；
Tracking shapes and drawing to the display

ArcGIS的每种控件都有属性可以设置，它们可以在可视化环境中进行编辑。将控件拖放到窗体上后，用户可以右键点击，选择“属性”菜单来编辑这些属性，它们可以让用户不编写一行代码的情况下快速构建一个GIS应用程序。


总的界面布局如下：

其xaml代码如下：

   
       
       
   

   
   
   
       
       
       
           
           
       
       
       
   

对应的主要的C#代码如下：

 代码如下 protected async override void OnNavigatedTo(NavigationEventArgs e)
    {
        var locator = new Geolocator();//开启位置
        locator.DesiredAccuracyInMeters = 50;//设置位置服务的准确度  50米

        var position = await locator.GetGeopositionAsync(); //得到当前的位置
        await myMap.TrySetViewAsync(position.Coordinate.Point,18D);// MapControl控件显示当前位置（point是纬度和经度；18D为当前精度
        mapSlider.Value = myMap.ZoomLevel;
       
    }

    private void GetPositionButton_Click(object sender, RoutedEventArgs e)
    {
        showMapTextblock.Text = string.Format("{0},{1}", myMap.Center.Position.Longitude, myMap.Center.Position.Latitude);
    }

    private async void SetPositonButton_Click(object sender, RoutedEventArgs e)
    {
        var setposition = new Windows.Devices.Geolocation.BasicGeoposition();
        setposition.Latitude=47;
        setposition.Longitude=-122;
        var mypoint=new Windows.Devices.Geolocation.Geopoint(setposition);
        if (await myMap.TrySetViewAsync(mypoint, 18D))
        {
            //
        }
    }
 

    private void mapSlider_ValueChanged(object sender, RangeBaseValueChangedEventArgs e)
    {
        if (myMap!=null)
        {
            myMap.ZoomLevel = e.NewValue;
            double tt;
            tt = e.NewValue / 18 * 100;
            sliderTextblock.Text = string.Format("{0}%", (int)tt);
        }
    }
}

同时还需注意在Package文件中把位置功能打开，相应步骤如下：

 

WP8.1 Study3：WP8.1中Animation应用

WP8.1上的Animation动画的API和WIN8/WIN8.1上的差不多，网上可以找到很多资料，同时可以去MSDN看官方文档。

下面是我参考一些资料，写出来的例子，希望以后有用。

xaml代码如下：

 代码如下
   
       
           
           
                                                 Storyboard.TargetProperty="Opacity"
                                 From="0"
                                 To="1"
                                 Duration="0:0:2"/>
           
           
                                                 Storyboard.TargetProperty="Opacity"
                                 From="1"
                                 To="0"
                                 Duration="0:0:2"/>
           
           
           
                                                      FillBehavior="HoldEnd"
                                      SpeedRatio="8"
                                      Duration="0:0:4"/>
           
           
                                                       SpeedRatio="0.1"
                                       Duration="0:0:4"/>
           
           
           
                                                Storyboard.TargetProperty="(Ellipse.Fill).(SolidColorBrush.Color)"
                                From="Red"
                                To="Blue"
                                Duration="0:0:2"/>
           
           
           
               
           

           
           
               
           
   
       
       
       
       
       
                       Source="blue.png"
               Opacity="0"
               Width="100"
               Height="100"
               ImageOpened="animatedImage_ImageOpened"/>
       
           
       
           
               
           
       
   

当前页面的主要C#代码如下：

 代码如下 private void show_Click(object sender, RoutedEventArgs e)
    {
        showAnimation.Begin();
        fadeinAnimation.Begin();
        coloranimation.Begin();
        storyboardPointerUp.Begin();
    }

    private void hide_Click(object sender, RoutedEventArgs e)
    {
        HideAnimation.Begin();

        fadeoutAnimation.Begin();
        storyboardPointerDown.Begin();
    }

    private void animatedImage_ImageOpened(object sender, RoutedEventArgs e)
    {

    }
