How do I replace my android app Google maps radius circle with a blue translucent one as in image also blue marker with blue circle?

I can make the circle have a particular outline and fill but it doesn't look anywhere near as nice as the one depicted in the image below. How do I do that? my code so far is below also.

Code:
Code:
        private GoogleMap googleMap;
    
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
    
            try {
                initilizeMap();
    
            } catch (Exception e) {
                e.printStackTrace();
            }
    
        }
        private void initilizeMap() {
            if (googleMap == null) {
                googleMap = ((MapFragment) getFragmentManager().findFragmentById(
                        R.id.map)).getMap();
    
    
                  LatLng latLng = new LatLng(28.982518, -81.542272);
                  gooleMap.addMarker(new MarkerOptions().position(latLng));
    
                  
                  Circle circle =  gooleMap.addCircle(new CircleOptions()
                  .center(new LatLng(28.982518, -81.542272))
                  .radius(1000)
                  .strokeColor(Color.RED)
                  .fillColor(Color.PURPLE));
    
    mMap.addCircle(new CircleOptions()
            .center(center)
            .radius(radius)
            .strokeWidth(0f)
            .fillColor(0x550000FF));
    
            }
        }
    
        @Override
        protected void onResume() {
            super.onResume();
            initilizeMap();
        }
    
    }
Android xml:

Code:
<?xml version="1.0" encoding="utf-8"?>
    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" >
    
        <fragment
            android:id="@+id/map"
            android:name="com.google.android.gms.maps.MapFragment"
            android:layout_width="match_parent"
            android:layout_height="match_parent"/>
    
    </RelativeLayout>
