我的 .cs 代码如下
and my .cs code is the following
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,它会加载地图,但片刻后我收到此异常
when i try to run my project, it loads the map but a few moments later i get this exception
附加信息:值不在预期范围内."
"Additional information: Value does not fall within the expected range."
当我执行contactosMaps.Layers.Add(pinLayer);"时
when i do the "contactosMaps.Layers.Add(pinLayer);"
我不能将带有图像的网格作为图钉吗?
can't i have that Grid with the image as a pushpin?
推荐答案
使用 Phone.Controls.Toolkit 如下所述:-
Use the Phone.Controls.Toolkit as described here:-
http://wp.qmatteoq.com/maps-in-windows-phone-8-and-phone-toolkit-a-spiring-team-part-1/
工具包可以在任何一个
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:-
You can then either add the image directly in your XAML as follows:-
<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>
或者您可以在 C# 中添加它,如下所示:-
or you can add it in C# as follows:-
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.
You should be able to add a Grid with an image instead of an ellipse as shown above.
如果这对您有用,请告诉我.
Let me know if this worked for you.
