Answer 1

for drawing circle in android map view you can try this:

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.center(point);
// Radius of the circle
circleOptions.radius(100);
// Border color of the circle
circleOptions.strokeColor(Color.BLACK);
// Fill color of the circle
circleOptions.fillColor(0x30ff0000);
// Border width of the circle
circleOptions.strokeWidth(2);
// Adding the circle to the GoogleMap
mMap.addCircle(circleOptions);

}
