android - How to get id of Marker clicked in Google Map inside setOnInfoWindowClickListener -

here trying set id inside doinbackground , call in setoninfowindowclicklistener.but problem is getting id of first element in list. want id of marker clicked. using variable private static string id; store id product.id=productjson.getstring("id"); id=product.id; assign it.

googlemap.setoninfowindowclicklistener(new oninfowindowclicklistener() {          @override         public void oninfowindowclick(marker arg0) {              intent.putextra("product_id",id);             system.out.println(id);             startactivity(intent);         } 

how can id ondoinbackground , use in intent.putextra().

    } }  } 

add product.id tag marker:

marker marker = googlemap.addmarker(new markeroptions()         .position(new latlng(product.lat, product.lon))         .title(product.name)         .icon(bitmapdescriptorfactory.frombitmap(product.icon))); marker.settag(product.id); 

and on oninfowindowclicklistener tag:

googlemap.setoninfowindowclicklistener(new oninfowindowclicklistener() {     @override     public void oninfowindowclick(marker marker) {         intent.putextra("product_id",(string) marker.gettag());         startactivity(intent);     } }

another option keep map<marker, string> store id associated each marker:

private map<marker, string> markerids = new hashmap<>(); 

you need create markers , store them this:

marker marker = googlemap.addmarker(new markeroptions().position(markerposition).title("my marker")); markerids.put(marker, product.id); 

and on oninfowindowclicklistener tag:

googlemap.setoninfowindowclicklistener(new oninfowindowclicklistener() {     @override     public void oninfowindowclick(marker marker) {         intent.putextra("product_id",markerids.get(marker));         startactivity(intent);     } }
