編程的windows phone開發(fā)學(xué)習(xí)筆記教程

WindowsPhone6)現(xiàn)在的智能中地圖應(yīng)用已經(jīng)成為基礎(chǔ)功能之外的最重要的功能之一了,在很多以通過GPS對當(dāng)前所在位置進行定位，返回當(dāng)前位置的，但是如果只是用來那就一目了然了，這在WindowsPhone開發(fā)中這很容易做到。BingMapsAPIWindowsPhoneWindowsPhoneMap非常簡單(這里是獲取Key的地址)，使用WindowsLive賬號登陸后:點擊“CreateorViewMapMap示模式:道路模式和航測模式。這是前臺頁面MainPage.xaml的代碼:<!--ContentPanel在此處放置其他內(nèi)容<Gridx:Name="ContentPanel"Grid.Row="1" Name="map1"Height="450"CredentialsProvider="你的Key值"><ButtonContent="航測模式 9<ButtonContent="放大 <ButtonContent="縮小 1///23///4///<param5///<param6privatevoidRoutedEventArgs7{8double9zoom=map1.ZoomLevel=}<param<param privatevoidbtnZoomOut_Click(objectRoutedEventArgse){doublezoom=map1.ZoomLevel=--}<param ///<param privatevoidbtnRoad_Click(objectsender,RoutedEventArgse){map1.Mode=new}<param<param privatevoidbtnAerial_Click(objectsender,RoutedEventArgse) map1.ModenewAerialMode(true);//true的構(gòu)造函 可以看到，Map控件已經(jīng)把很多常用的功能封裝得非常好了，只需要我們簡單的調(diào)用MapWindowsPhoneMap使用位置服務(wù)，在地圖中對我們的所在地進行定位；以及如何在地圖中添加圖釘 <!--ContentPanel在此處放置其他內(nèi)容2<Grid3 VerticalAlignment="Top"CredentialsProvider="你的Map <ButtonContent="定位"VerticalAlignment="Bottom"Name="btn_Location"Click="btn_Location_Click"/> 1publicpartialclassMainPage:2{3GeoCoordinateWatcher45public6{78}9/////////<param///<param privatevoidbtn_Location_Click(objectsender,RoutedEventArgse){if(watcher=={=;//watcher.MovementThreshold=20;//PositionChanged之間傳送的最小距離watcher.PositionChanged+=new//}}PositionChangedvoidwatcher_PositionChanged(objectsender,GeoPositionChangedEventArgs<GeoCoordinate>e) LocationlocationnewLocation();//實例化一個位置位置//將當(dāng)前的值賦給位置對location.Latitude=location.Longitude=e.Position.Location.Longitude;PushpinpushpinnewPushpin();//pushpin.Content"當(dāng)前位置pushpin.Location=location;this.map1.SetView(location10);//縮放界別為10(1- BingMapsSOAPBingMapsSOAPServices，通過使用這些服務(wù)可以使我們能夠使我地理編碼服務(wù)（GeocodeService）,服務(wù)地址是：路由功能服務(wù)（RouteService）,服務(wù)的地址是:地理編碼服務(wù)可以通過搜索地名來匹配在地圖上對應(yīng)的位置(經(jīng)度和緯度),或者通過實路由功能服務(wù)可以通過計算地點的坐標(biāo)來顯示線路的功能比如在地圖中常用的駕下面讓我們通過一個示例來了解如何使用這些服務(wù)，在WindowsPhone中實現(xiàn)我們在地圖應(yīng)用中常見的出行路徑計算的功能首先添加前面給出地址的兩個服務(wù)，<Gridx:Name="LayoutRoot"<RowDefinition<RowDefinition<!--ContentPanel在此處放置其他內(nèi)容<Gridx:Name="ContentPanel"<GridHeight="530"<my:MapName="map1"CredentialsProvider="Map<GridGrid.Row="1"<StackPanel<TextBlockText= FontSize="28"></TextBlock><TextBoxWidth="400"Height="80"HorizontalAlignment="Right"Name="txtStartPath"></TextBox><TextBlockText= FontSize="28"></TextBlock><TextBoxWidth="400"Height="80"HorizontalAlignment="Right"Name="txtStopPath"></TextBox><ButtonHeight="80"Content="查找路徑" 1partialclassMainPage:2{34public5{67}89<param<param privatevoidbtnQueryPath_Click(objectsender,RoutedEventArgse){geocodeResults=new,,}<param publicvoidGetGeocodeAsync(stringstrAddress,int{{= //綁定,查詢完成后發(fā)pleted+= GeocodeRequestrequest=new//設(shè)request.Credentials=request.Credentials.ApplicationId=//request.Query=.GeocodeAsync(request, catch(Exception{ //使用全局變量來起點和終點的位置信internalGeocodeResult[]geocodeResults;/////////<param///<param privatevoid pleted(objectsender,pletedEventArgse) if(e.Error== intwaypointIndex geocodeResults[waypointIndex]= booldoneGeocoding=true; foreach(GeocodeService.GeocodeResultgrin{if(gr=={doneGeocoding=} if{ }<paramprivatevoidCalculateRoute(GeocodeResult[]{ routeService=new //綁定回調(diào)函 pleted+=new //設(shè)RouteRequestrouteRequest=newrouteRequest.Credentials=newrouteRequest.Credentials.ApplicationId=routeRequest.Options=newrouteRequest.Options.RoutePathType= routeRequest.Waypoints=newforeach(GeocodeResultresultin{}}///Geocode//////<param///privateWaypointGeocodeResultToWaypoint(GeocodeResult{Waypointwaypoint=newwaypoint.Description waypoint.Location=newwaypoint.Location.Latitudewaypoint.Location.Longitude=return}<param<param pletedEventArgs {//if((e.Result.ResponseSummary.StatusCode== (e.Result.Result.Legs.Count!=0)){ColorrouteColor=SolidColorBrushrouteBrush= MapPolyline ine=new ine.Locations= ine.Stroke= ine.Opacity= ine.StrokeThickness= //循環(huán)返回的路線信 foreach(Locationp Locationlocation=new Longitude= Latitude= yer ayer=new foreach(GeocodeService.GeocodeResultgrin Ellipsepoint=new point.Width= point.Height= point.Fill=point.Opacity=Locationlocation=new{Latitude=Longitude=// ayer.AddChild(point,}varrouteModel= LocationRectrect }}catch(Exception{}}}//////publicclass{privatereadonlyLocationCollection//////publicICollection<GeoCoordinate>
