windows phone7中使用bing中文地图和Google地图
之前在windows phone中使用map控件时,一直加载出来的是英文的bing map,一直以为要等ms提供汉化的map;而同时google和baidu等未发现对应的map sdk或api,那个苦恼啊,使用英文bing map那个痛苦啊;期间看到一些使用加载titlesource 加载google地图或者bing map中文地图的方法;但是这些方法都是非正式处理方法,担心应用发布后会遇到问题;后来从nokia那得到消息,nokia会出正式的windows phone地图,但是需要走商业合同... ...,我只整理了下如何加载中文bingmap和google map的方法;源码
实现的大致思路都是重写titlesource,在bingmap control中添加一个层,将对应titlesource加载到这个层上显示;
方法是定义两个类继承自Microsoft.Phone.Controls.Maps.TileSource,然后重写geturl方法;
代码如下:
View Code
public class GoogleTitleSource : TileSource { public GoogleTitleSource() : base("http://khm{0}.google.com/kh/v=47&x={1}&y={2}&z={3") { } public override Uri GetUri(int x, int y, int zoomLevel) { return new Uri(string.Format(this.UriFormat, x % 4, x, y, zoomLevel)); } } public class BingChinaTitleSource : TileSource { public BingChinaTitleSource() : base("http://r2.tiles.ditu.live.com/tiles/r{quadkey}.png?g=4") { } }
再在page loaded事件中添加对应map的层和源
View Code
private void PhoneApplicationPage_Loaded(object sender, RoutedEventArgs e) { //bing MapTileLayer bingtileLayer = new MapTileLayer(); bingtileLayer.Width = 431; bingtileLayer.Height = 540; GeoCoordinate center = new GeoCoordinate(36,104); TileSource tileSource = new BingChinaTitleSource(); bingtileLayer.TileSources.Add(tileSource); bingtileLayer.Opacity = 0.9; bingMap.Children.Add(bingtileLayer); bingMap.Mode = new MercatorMode(); bingMap.Center = center; //google MapTileLayer googletileLayer = new MapTileLayer(); googletileLayer.Width = 431; googletileLayer.Height = 540; TileSource googletileSource = new GoogleTitleSource(); googletileLayer.TileSources.Add(tileSource); googletileLayer.Opacity = 0.9; google.Children.Add(googletileLayer); google.Mode = new MercatorMode(); google.Center = center; bingEng.Center = center; }
ui中使用全景视图,分别添加两个Map控件
View Code
<controls:Panorama Grid.Row="1" Height="722" HorizontalAlignment="Left" Margin="0,0,0,0" Title="maps" VerticalAlignment="Top" Width="479" FontSize="26.667" Style="{StaticResource PanoramaStyle1}"> <controls:PanoramaItem Header="Bing Map Chinese" Style="{StaticResource PanoramaItemStyle1}"> <Grid Height="579" Width="434"> <my:Map x:Name="bingMap" Height="578" LogoVisibility="Collapsed" CopyrightVisibility="Collapsed" HorizontalAlignment="Left" Margin="3,1,0,0" VerticalAlignment="Top" Width="431" ZoomLevel="3" /> </Grid> </controls:PanoramaItem> <controls:PanoramaItem Header="Google Map" Style="{StaticResource PanoramaItemStyle1}"> <Grid Height="578" Width="426"> <my:Map x:Name="google" Height="578" LogoVisibility="Collapsed" CopyrightVisibility="Collapsed" HorizontalAlignment="Left" Margin="3,1,0,0" VerticalAlignment="Top" Width="431" ZoomLevel="3" /> </Grid> </controls:PanoramaItem> <controls:PanoramaItem Header="bing Map englsh" Style="{StaticResource PanoramaItemStyle1}"> <Grid Height="557" Width="426"> <my:Map x:Name="bingEng" Height="549" ZoomLevel="3" LogoVisibility="Collapsed" CopyrightVisibility="Collapsed" HorizontalAlignment="Left" Margin="3,1,0,0" VerticalAlignment="Top" Width="416" /> </Grid> </controls:PanoramaItem> </controls:Panorama>
运行效果
从体验来说bing中文和google似乎差别不大,但是bing英文 ui显示元素太少;
