Info Window on shapes(circle, polygon) in Android Maps App

I have an android app which one of its screens uses google maps, and I load some regions on it. I want to be able to click on a region/shape(circle or polygon) and an info window to appear. I am searching but I cant find enough information on how to show info windows on shapes, only on markers. Is that not a common practice? What should I do? Could anyone help, even theoretically? Any help or direction would be appreciated, thank you very much!

  1. Create a customCircleOnClickListener (or don't and use the title and snippet properties, as I am doing in step 3).

  2. Then add:

    mMap.setInfoWindowAdapter(new
CustomInfoWindowAdapter(MainActivity.this));
mMap.setOnCircleClickListener(customCircleOnClickListener());

  3. Finally: 

    public GoogleMap.OnCircleClickListener customCircleOnClickListener() {
    return new GoogleMap.OnCircleClickListener() {
        @Override
        public void onCircleClick(Circle circle) {
            Log.d("MainActivity", "Clicked a ball!");

            POIAnnotationCircle annotCircle = annotationsByCircle.get(circle);
            markerForInfoWindow = mMap.addMarker(new MarkerOptions()
                    .alpha(0.0f)
                    .infoWindowAnchor(.6f,1.0f)
                    .position(annotCircle.getCoordinate())
                    .title(annotCircle.getTitle())
                    .snippet(annotCircle.getSnippet()));

            markerForInfoWindow.showInfoWindow();
        }
    };
}
