Xamarin Android: Create Google Map Draw Circle Around Marker

Let’s start,

We already created a Google Map with Marker in my article. If you did not create this please follow this link,

After creating Google Map with Marker App in Xamarin Android, then follow the below steps,

Step 1: Open MainActivity.cs page, then give following code,

Name Space:

C# Code:

public void OnMapReady(GoogleMap googleMap)
{
this.GMap = googleMap;
GMap.UiSettings.ZoomControlsEnabled = true;
DrawCircle(GMap); //Calling Draw Circle
LatLng latlng = new LatLng(Convert.ToDouble(13.0291), Convert.ToDouble(80.2083));
CameraUpdate camera = CameraUpdateFactory.NewLatLngZoom(latlng, 15);
GMap.MoveCamera(camera);
MarkerOptions options = new MarkerOptions()
.SetPosition(latlng)
.SetTitle("Chennai");
GMap.AddMarker(options);
}
public void DrawCircle(GoogleMap gMap)
{
Circle circle;
var CircleMaker = new CircleOptions();
var latlong = new LatLng(13.0291, 80.2083); //Location
CircleMaker.InvokeCenter(latlong); //
CircleMaker.InvokeRadius(1000); //Radius in Circle
CircleMaker.InvokeStrokeWidth(4);
CircleMaker.InvokeStrokeColor(Android.Graphics.Color.ParseColor("#e6d9534f")); //Circle Color
CircleMaker.InvokeFillColor(Color.Argb(034, 209, 72, 54));
CameraUpdate camera = CameraUpdateFactory.NewLatLngZoom(latlong, 15); //Map Zoom Level
circle = GMap.AddCircle(CircleMaker); //Gmap Add Circle
}

Step 2: Next Run the app showing Drawing Circle in Around Marker with Google Map,

Finally, we have successfully created Xamarin Android Google Map Draw Circle around Marker App.
