Interact with Points of Interest on Google Maps

Question

I am working on Android Studio with the Maps Api. On the shown map, there are markers that have been already placed by Google (see picture below).

Is there a way to interact with them by clicking to get more information (e.g. id of marker/place)?

Answer 1

The predefined markers added by Google are called Points of Interest (POI). The GoogleMaps class provides a special listener for POIs: GoogleMap.OnPoiClickListener

You can find corresponding documentation in

https://developers.google.com/maps/documentation/android-sdk/reference/com/google/android/libraries/maps/GoogleMap.OnPoiClickListener

https://developers.google.com/maps/documentation/android-sdk/reference/com/google/android/libraries/maps/model/PointOfInterest

The code snippet should be something like

mMap.setOnPoiClickListener(new GoogleMap.OnPoiClickListener() {
    @Override
    public void onPoiClick(PointOfInterest poi) {
        String placeId = poi.placeId;
        //TODO: get details for place id
    });
}

I hope this helps!

Answer 2

you can use onMarkerClickListener shown below :

mMap.setOnMarkerClickListener(new GoogleMap.OnMarkerClickListener() {
    @Override
    public boolean onMarkerClick(Marker marker) {

    });
}

where mMap is an instance of GoogleMap
