try this cipher 

                  protected invalidate onCreate(Bundle savedInstanceState) {             topnotch.onCreate(savedInstanceState);             setContentView(R.layout.activity_tag_map);       // Drawing off circle on the map            drawCircle(new LatLng(Latitude, Longitude));     }          private void drawCircle(LatLng point){                  // Instantiating CircleOptions to draw a circle around the marker                 CircleOptions circleOptions = new CircleOptions();                  // Specifying the center of the circle                 circleOptions.eye(point);                  // Radius of the circle                 circleOptions.radius(20);                  // Borderline color of the circle                 circleOptions.strokeColor(Colouring.Pitch-dark);                  // Fill color of the rope                 circleOptions.fillColor(0x30ff0000);                  // Border breadth of the circle                 circleOptions.strokeWidth(2);                  // Adding the circle to the GoogleMap                 googleMap.addCircle(circleOptions);              }

  • yes IT dandy but my task is to manage the marker circle from the seek measure

    Jul 10 '15 at 6:35

  • public nothingness onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) { // TODO Motorcar-generated method ticket stub in favour of=progress; googleMap.addCircle(new CircleOptions() .center(new LatLng(point.parallel,point.longitude)) .radius(affirmative) .strokeWidth(0f) .fillColor(0x550000FF) );

  • How would you survive so the circle remains in the center of the map as the user moves crosswise the map out?

    Jan 19 '18 at 7:04

Add the pursual code in onMapReady() method:

                Circle circle = map out.addCircle(new CircleOptions()      .pore(new LatLng(latitude, longitude))      .radius(10000)      .strokeColor(Color.Red ink)      .fillColor(Color.BLUE));

where map is the object of GoogleMap class.

Google Maps can use rig-transparent color for the circle.

                private volt-ampere circle: Circle? = null  private fun drawCircle(latitude: Three-fold, longitude: Double, radius: Double) {     val circleOptions = CircleOptions()         .center(LatLng(latitude, longitude))         .r(radius)         .strokeWidth(1.0f)         .strokeColor(ContextCompat.getColor(context!!, R.colorise.color1))         .fillColor(ContextCompat.getColor(context of use!!, R.color.color2))     circle?.remove() // Remove old R-2.     circle = googleMap?.addCircle(circleOptions) // Draw late lap. }

                                      CircleOptions circleOptions = new-sprung CircleOptions();                 circleOptions.center(new LatLng(positioning.getLatitude(),location.getLongitude()));                 circleOptions.radius(700);                 circleOptions.fillColor(Color.TRANSPARENT);                 circleOptions.strokeWidth(6);                 mMap.addCircle(circleOptions);             geocoder = new Geocoder(MapsActivity.this, getDefault());             MarkerOptions markerOptions = new MarkerOptions();             markerOptions.position(new LatLng(location.getLatitude(), location.getLongitude()));             mMap.addMarker(markerOptions.title(Twine.valueOf(position)));

  • While this code snipping may be the solution, including an account really helps to improve the quality of your spot. Remember that you are answering the question for readers in the future, and those hoi polloi might not know the reasons for your code proffer.

Kotlin version of @Lalit Kushwah

                correspondenc.addCircle(     CircleOptions()         .center([Your LatLng])         .r(10000.0)         .strokeColor(Coloring material.RED)         .fillColor(Color.BLUE) )
