Circle within Circle in Android

This is my Below code which only draws one Circle around Current Location as the center. I need to draw a Circle within Circle around the current location on the google map. Total circle should be 5. Radius of each circle should be like this-

Code:

---

Circle 1 radius should be 10m
Circle 2 radius should be 20m
Circle 3 radius should be 30m
Circle 4 radius should be 40m
Circle 5 radius should be 50m

Below code works fine to create only one circle by taking the current location as the center. But how can I draw other circles with the above specification.

Code:

---

        class MapOverlay extends Overlay {
                private GeoPoint pointToDraw;

                public void setPointToDraw(GeoPoint point) {
                        pointToDraw = point;
                }

                public GeoPoint getPointToDraw() {
                        return pointToDraw;
                }

                @Override
                public boolean draw(Canvas canvas, MapView mapView, boolean shadow, long when) {
                        super.draw(canvas, mapView, shadow);
                        //---translate the GeoPoint to screen pixels---
                        Point screenPts = new Point();
                        mapView.getProjection().toPixels(pointToDraw, screenPts);
                        //--------------draw circle----------------------
                        Point pt = mapView.getProjection().toPixels(pointToDraw,screenPts);
                        Paint circlePaint = new Paint(Paint.ANTI_ALIAS_FLAG);
                        circlePaint.setColor(0x30000000);
                        circlePaint.setStyle(Style.FILL_AND_STROKE);
                        canvas.drawCircle(screenPts.x, screenPts.y, 130, circlePaint);

                        //---add the marker---
                        Bitmap bmp = BitmapFactory.decodeResource(getResources(), R.drawable.current_user);
                        canvas.drawBitmap(bmp, screenPts.x, screenPts.y-bmp.getHeight(), null);
                        super.draw(canvas,mapView,shadow);

                        return true;
                }


        }

I am having hard time making other circles by taking current location as the center. R.drawable.current_user is the current location
