Java Errors in Android App -

i'm trying to implement addproximityalert when info window clicked

googlemap.setoninfowindowclicklistener(             new oninfowindowclicklistener(){                 public void oninfowindowclick(marker marker) {      public void addproximityalert(double latitude, double longitude){                latlng clickedmarkerlatlng = marker.getposition();                     double lat =  clickedmarkerlatlng.latitude;                     double long1 =  clickedmarkerlatlng.longitude;                  log.e("hello", "output=" + lat + long1);                     locationmanager lm;              //   double lat=123,long1=34;    //defining latitude & longitude                   float radius=30;                         //defining radius             intent intent = new intent(prox_alert_intent);             pendingintent proximityintent = pendingintent.getbroadcast(this, 0, intent, 0);             locationmanager.addproximityalert(                 lat, // latitude of central point of alert region                 long1, // longitude of central point of alert region                 point_radius, // radius of central point of alert region, in meters                 prox_alert_expiration, // time proximity alert, in milliseconds, or -1 indicate no expiration                 proximityintent // used generate intent fire when entry or exit alert region detected            );            intentfilter filter = new intentfilter(prox_alert_intent);             registerreceiver(new proximityintentreceiver(), filter);         }      }  }); 

this has "java errors" , i'm unsure how fix them. apparently in line public void addproximityalert(double latitude, double longitude){ brackets , comma aren't necessary, despite them being needed. can help?

edit: ok, i've implemented of answers below, i'm still having problems. getbroadcast method undefined type infowindowclicklistener. suggestions?

you have 2 merged method declarations:

public void oninfowindowclick(marker marker) {  public void addproximityalert(double latitude, double longitude){ 

not sure intent is, need close off declaration of oninfowindowclick(marker marker) before beginning declaration of addproximityalert
