这里介绍怎样进行Bing Maps的开发。首先我们须要在我们的程序中引入Bing Map的SDK。详细方法,这里推荐一个链接<win8>使用Bing地图。这样一个hello world便出来了。这里主要介绍一些主要的API。进行一些基础性的开发。

在整个开发中,给我感触最深的是。在网上资料稀少的情况下。查看研究Bing Map给出的API是最有效的方法(Map API)。

或许API的凝视是模棱两可,但仅仅要我们去试。便能了解这些方法的功能。

假设遇到hello world不能显示地图,在C#文件里类的构造方法中加入myMap.HomeRegion = "US"(myMap是XAML中定义的Map,详细见以下的演示样例代码)

using Windows.UI;
using Windows.UI.Popups;
using Windows.UI.Xaml;
using Windows.UI.Xaml.Controls;
using Windows.UI.Xaml.Controls.Primitives;
using Windows.UI.Xaml.Data;
using Windows.UI.Xaml.Input;
using Windows.UI.Xaml.Media;
using Windows.UI.Xaml.Navigation;

// “空白页”项模板在 http://go.microsoft.com/fwlink/?

LinkId=234238 上有介绍 namespace demo02 { /// <summary> /// 可用于自身或导航至 Frame 内部的空白页。

/// </summary> public sealed partial class BingMap : Page { public BingMap() { this.InitializeComponent(); myMap.HomeRegion = "US"; } } }



(一)加入图钉:

                </bm:Pushpin>

                        <bm:Location Latitude="23.16" Longitude="113.23" />
                       
                    </bm:MapLayer.Position>
                </bm:Pushpin>
                
            </bm:Map.Children>

        </bm:Map>
    </Grid>
   
</Page>

xmlns:bm="using:Bing.Maps"将SDK引入程序。

Pushpin是图钉,Tapped是点击该图钉触发的方法。方法在C#文件里定义。Location的属性有经纬度。这是图钉在地图上的坐标。除了在XAML中静态设置图钉,我们还能够通过编程动态加入。

            pushpin.Tapped += BJTapped; //点击图钉触发的方法
            myMap.Children.Add(pushpin);

        }

            location.Latitude = 39.92;
            location.Longitude = 116.46;
            myMap.SetView(location, 12); //将视图放大到北京地区

或许对于鼠标移到图钉上的文字显示的样式不惬意。比方某个图钉是一个景点,当我们将鼠标移到它上面是时,最好能出现照片。

这时可借助样式Style。

在App.xaml中加入例如以下:

<Style TargetType="ToolTip"  x:Key="okStyle">
                <Setter Property="Background" Value="Transparent" />
                <Setter Property="BorderBrush" Value="Transparent" />
                <Setter Property="BorderThickness" Value="0" />
                <Setter Property="Template">
                    <Setter.Value>
                        <ControlTemplate>
                            <Border CornerRadius="5">
                                <Border.Background>
                                    <SolidColorBrush Color="Black" Opacity="0.5"/>
                                </Border.Background>
                                <ContentPresenter Margin="5">
                                    <ContentPresenter.Content>
                                        <StackPanel Margin="5" MaxWidth="200" MinHeight="80">
                                            <TextBlock Text="山东大学 SHANDONG UNIVERSITY"  FontSize="12" Foreground="White"/>
                                            <Image Source="Images/EC/SD/SDU/sdu.jpg" Grid.ColumnSpan="5" Margin="0,0,0,10" Stretch="Fill" />
                                        </StackPanel>
                                    </ContentPresenter.Content>
                                </ContentPresenter>
                            </Border>
                        </ControlTemplate>
                    </Setter.Value>
                </Setter>
            </Style>

位置是:

<Application
    x:Class="demo02.App"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

                <!--<ResourceDictionary Source="Common/StandardStyles.xaml"/>-->

                <!-- Add app resurces to this resource dictionary -->

                    <!--<RssData:DateConverter x:Key="dateConverter" />-->

                </ResourceDictionary>

            </ResourceDictionary.MergedDictionaries>
            <Style TargetType="ToolTip"  x:Key="okStyle">
                <Setter Property="Background" Value="Transparent" />
                <Setter Property="BorderBrush" Value="Transparent" />

                                <Border.Background>
                                    <SolidColorBrush Color="Black" Opacity="0.5"/>
                                </Border.Background>
                                <ContentPresenter Margin="5">
                                    <ContentPresenter.Content>
                                        <StackPanel Margin="5" MaxWidth="200" MinHeight="80">
                                            <TextBlock Text="山东大学 SHANDONG UNIVERSITY"  FontSize="12" Foreground="White"/>
                                            <Image Source="Images/EC/SD/SDU/sdu.jpg" Grid.ColumnSpan="5" Margin="0,0,0,10" Stretch="Fill" />
                                        </StackPanel>
                                    </ContentPresenter.Content>
                                </ContentPresenter>
                            </Border>
                        </ControlTemplate>
                    </Setter.Value>
                </Setter>
            </Style>
        </ResourceDictionary>
    </Application.Resources>
</Application>

这样样式便定义好了。接下来看怎样使用:

//用图钉标注山东大学36.677549,117.054218
            var pushpin = new Pushpin();
            //ToolTipService.SetToolTip(pushpin, "山东大学");

            ToolTipService.SetToolTip(pushpin, new ToolTip()
            {
                Style = Application.Current.Resources["okStyle"] as Style
            });

            MapLayer.SetPosition(pushpin, new Location(36.677549, 117.054218));
            pushpin.Tapped += SDU01Tapped;
            myMap.Children.Add(pushpin);

(二)连线:

有了点,以下是线。能描绘出一块指定区域。

以下的代码将山大济南六个校区连接起来。

(PS:能够通过谷歌地图获得某个地点的API,方法是将鼠标放在某个地点,右键选择“这是哪里?”便会在搜索框中出现精确的经纬度)

//连接六大校区
            MapLayer mPinLayer = new MapLayer();
            myMap.Children.Add(mPinLayer);
            MapShapeLayer mShapeLayer = new MapShapeLayer();
            myMap.ShapeLayers.Add(mShapeLayer);

			//定义要连接起来的点
            LocationCollection mPolyShapeLocations01 = new LocationCollection();
            mPolyShapeLocations01.Add(new Location(36.666818, 117.133137)); //软件园
            mPolyShapeLocations01.Add(new Location(36.68525, 117.060184)); //洪家楼
            mPolyShapeLocations01.Add(new Location(36.678625, 117.050547)); //中心
            mPolyShapeLocations01.Add(new Location(36.650681, 117.013094)); //趵突泉
            mPolyShapeLocations01.Add(new Location(36.650414, 117.022868)); //千佛山
            mPolyShapeLocations01.Add(new Location(36.602489, 117.049045)); //兴隆山
            mPolyShapeLocations01.Add(new Location(36.666818, 117.133137)); //软件园

            for (int i = 0; i < mPolyShapeLocations01.Count; i++)
            {
                Pushpin pin = new Pushpin();
                pin.Text = i.ToString();
                mPinLayer.Children.Add(pin);
                MapLayer.SetPosition(pin, mPolyShapeLocations01[i]);
            }

			//MapPolylines是连线的API,将上面定义的点连接起来
            MapPolyline polyline01 = new MapPolyline();
            polyline01.Color = Windows.UI.Colors.Red;
            polyline01.Locations = mPolyShapeLocations01;
            polyline01.Width = 5.0;


            mShapeLayer.Shapes.Add(polyline01);
