c# - 在 map 上作为图钉的图像 - Windows Phone 8

Question

我正在尝试将图像添加到 Windows Phone 8 map ，以用作图钉

我的 XAML 中有以下代码

            <LineBreak/>
            <Run Text="Portugal"/>
            <LineBreak/>
            <Run/>
        </TextBlock>
        <TextBlock HorizontalAlignment="Left" Margin="30,745,0,0" TextWrapping="Wrap" VerticalAlignment="Top" Grid.ColumnSpan="2" Width="406" Height="22" Text="Tel. (+351) 266 748 300 "/>
        <TextBlock HorizontalAlignment="Left" Margin="30,773,0,0" TextWrapping="Wrap" VerticalAlignment="Top" Grid.ColumnSpan="2" Width="406" Height="22">
            <Run FontFamily="Helvetica" Text="Fax. (+ 351) 266 705 149"/>
            <Run FontFamily="Helvetica"/>
            <Run/>
        </TextBlock>

    </Grid>
</Grid>

我的 .cs 代码如下

public partial class Contactos : PhoneApplicationPage
{
    public Contactos()
    {
        InitializeComponent();
        Loaded +=Contactos_Loaded;

    }

    private void Contactos_Loaded(object sender, RoutedEventArgs e)
    {
        UpdateMap();
    }

    private void UpdateMap()
    {

        MapOverlay pin = new MapOverlay();
        pin.Content = pushRed;
        pin.GeoCoordinate = new GeoCoordinate(38.57325D, -7.90546);
        pin.PositionOrigin = new Point(0, 0.5);

        MapLayer pinLayer = new MapLayer();
        pinLayer.Add(pin);
        contactosMaps.Layers.Add(pinLayer);
        contactosMaps.SetView(new GeoCoordinate(38.57325D, -7.90546), 14D);
    }

    private void Contactos_Btn1_Click(object sender, RoutedEventArgs e)
    {

    }
}

当我尝试运行我的项目时，它加载了 map ，但片刻之后我得到了这个异常

“附加信息:值不在预期范围内。”

当我执行“contactosMaps.Layers.Add(pinLayer);”时

我不能将带有图像的网格作为图钉吗？

按照此处所述使用 Phone.Controls.Toolkit:-

http://wp.qmatteoq.com/maps-in-windows-phone-8-and-phone-toolkit-a-winning-team-part-1/

工具包可以在以下任一位置找到

http://phone.codeplex.com/

或

https://www.nuget.org/packages/WPtoolkit

然后您可以直接在 XAML 中添加图像，如下所示:-

<maps:Map Loaded="MapControl_Loaded" ZoomLevel="18" Name="MapControl">
   <toolkit:MapExtensions.Children>
       <toolkit:Pushpin x:Name="MyPushpin">
           <toolkit:Pushpin.Template>
               <ControlTemplate TargetType="toolkit:Pushpin">
                   <StackPanel>
                       <Image Source="/Images/MapScreen/MapScreenCurrentLocationPin.png" Stretch="Uniform" Width="50" Height="50" HorizontalAlignment="Center"/>
                    </StackPanel>
                </ControlTemplate>
            </toolkit:Pushpin.Template>
        </toolkit:Pushpin>
    </toolkit:MapExtensions.Children>
</maps:Map>

或者您可以按如下方式在 C# 中添加它:-

MapOverlay overlay = new MapOverlay
{
    GeoCoordinate = myMap.Center,
    Content = new Ellipse
    {
        Fill = new SolidColorBrush(Colors.Red),
        Width = 40,
        Height = 40
     }
};
MapLayer layer = new MapLayer();
layer.Add(overlay);

myMap.Layers.Add(layer);

您应该能够添加带有图像的网格，而不是如上所示的椭圆。

如果这对您有用，请告诉我。
