Description
This article describes how to use Google Maps API to show Google Maps using ImageryLayer of the Xamarin Maps(SfMaps) control.
Solution:
You can show the Google Maps using the RequestTileUri event of ImageryLayer.
Step 1: Subscribe the RequestTileUri event of ImageryLayer as demonstrated in the following code example.
XAML:
<maps:SfMaps> <maps:SfMaps.Layers> <maps:ImageryLayer RequestTileUri="ImageryLayer_RequestTileUri"> <maps:ImageryLayer.MarkerSettings> <maps:MapMarkerSetting MarkerIcon="Image" ImageSource="pin.png" IconSize="15"/> </maps:ImageryLayer.MarkerSettings> <maps:ImageryLayer.Markers> <maps:MapMarker Latitude="38.8833" Longitude= "-77.0167"/> <maps:MapMarker Latitude="-15.7833" Longitude= "-47.8667"/> <maps:MapMarker Latitude="21.0000" Longitude= "78.0000"/> <maps:MapMarker Latitude="35.0000" Longitude= "103.0000" /> <maps:MapMarker Latitude="-4.0383" Longitude= "21.7586" /> </maps:ImageryLayer.Markers> </maps:ImageryLayer> </maps:SfMaps.Layers> </maps:SfMaps>
Step 2: In the RequestTileUri event, assign the Google Maps API Uri link (or any tile maps provider) to corresponding x, y, and zoom level of the Uri property of TileUriArgs as demonstrated in the following code example.
C#
/// <summary>
/// This event is used to pass the uri of desired maps tile provider.
/// </summary>
/// <param name="sender">The imagery layer</param>
/// <param name="e">The Tile uri arguments</param>
private void ImageryLayer_RequestTileUri(object sender, Syncfusion.SfMaps.XForms.TileUriArgs e)
{
var link = "http://mt1.google.com/vt/lyrs=y&x=" + e.X.ToString() + "&y=" + e.Y.ToString() + "&z=" + e.ZoomLevel.ToString();
e.Uri = link;
}
