I am trying to add all users to a List which are within a certain distance from a users location. I have successfully gotten a users current location and I store this in my database using geofire. I know I have to use geofire to query the results but I am unsure on how to add the users to my list. I believe that this is done within the onKeyEntered method but I am unsure.

 private void addLocationToDB()

 database = FirebaseDatabase.getInstance().getReference("Leaderboard").child(userID);

 geoFire = new GeoFire(database);

 geoFire.setLocation("Location", new GeoLocation(latitude, longitude), new GeoFire.CompletionListener()
 
 @Override
 public void onComplete(String key, DatabaseError error)
 
 if(error != null)
 
 Log.d(TAG, "Problem storing users location - onComplete: " + error.getMessage());
 

 else
 
 getListNearbyUsers();
 
 
 );


private void getListNearbyUsers()

 geoQuery = geoFire.queryAtLocation(new GeoLocation(latitude, longitude), 1);

 geoQuery.addGeoQueryEventListener(new GeoQueryEventListener()
 
 @Override
 public void onKeyEntered(String key, GeoLocation location)
 
 nearbyUsers.add(key);
 

 @Override
 public void onKeyExited(String key)
 

 

 @Override
 public void onKeyMoved(String key, GeoLocation location)
 

 

 @Override
 public void onGeoQueryReady()
 

 

 @Override
 public void onGeoQueryError(DatabaseError error)
 

 
 );

Anyone looking for the answer I figured out my mistake. This method should take the userID as a argument not "Location". I can then get all "keys" as userID and filter the data. Hope this helps anyone with the same problem.

geoFire.setLocation("Location", new GeoLocation(latitude, longitude), new GeoFire.CompletionListener()

 @Override
 public void onComplete(String key, DatabaseError error)
 
 if(error != null)
 
 Log.d(TAG, "Problem storing users location - onComplete: " + error.getMessage());
 

 else
 
 getListNearbyUsers();
 
 
);

I hope this might Help,gets users in a radius of 10km/10000m

Location mLastLocation;
boolean getUsersAroundStarted = false; 
private void getDriversAround()

 getUsersAroundStarted=true;
 database = FirebaseDatabase.getInstance().getReference("Leaderboard").child(userID);

 GeoFire geoFire = new GeoFire(database);
 GeoQuery geoQuery = geoFire.queryAtLocation(new GeoLocation(mLastLocation.getLatitude(),mLastLocation.getLongitude()), 10000);
 geoQuery.addGeoQueryEventListener(new GeoQueryEventListener() 
 @Override
 public void onKeyEntered(String key, GeoLocation location) 
 //add users to Firebase Database
 
 );
