Android 是否可以从GeoFirestore查询中删除当前用户？

如果查询半径为100公里的用户，如何将自己（当前用户）排除在查询之外？

因为当onDocumentMoved触发时，如果您是唯一一个在输入的文档上触发移动的人，您将再次获得用户，但您与用户之间的距离不同，因此，如果您使用OnDocumentEnter方法将他们添加到数据库中，您将获得重复的结果。我解决这个问题的方法是在再次打开应用程序时从数据库中删除所有usersInRange。我知道这不是一个完美的解决方案，我正在寻找一个更好的解决方案

以下是我的代码：

  public void getLocation(Location location){
    ArrayList<String> docMoved = new ArrayList<>();
    listenerRegistration = documentReference.addSnapshotListener(new EventListener<DocumentSnapshot>() {
        @Override
        public void onEvent(@Nullable DocumentSnapshot value, @Nullable FirebaseFirestoreException error) {
            if(value != null && value.exists()){
                if (value.get("LocationRange") != null && value.get("AgeRangeFrom") != null && value.get("AgeRangeTo") != null && value.getString("InterestInGender") != null) {
                    locationRange = (double) value.get("LocationRange");
                    ageRangeFrom = (double) value.get("AgeRangeFrom");
                    ageRangeTo = (double) value.get("AgeRangeTo");
                    interestInGender = value.getString("InterestInGender");
                    ArrayList<HashMap<Object, Object>> usersInRange = (ArrayList<HashMap<Object, Object>>) value.get("UsersInRange");

                    geoQuery = geoFirestore.queryAtLocation(new GeoPoint(location.getLatitude(), location.getLongitude()), locationRange);

                    geoQuery.addGeoQueryDataEventListener(new GeoQueryDataEventListener() {
                        @Override
                        public void onDocumentEntered(@NotNull DocumentSnapshot documentSnapshot5, @NotNull GeoPoint geoPoint) {
                            if (documentSnapshot5.get("age") != null && documentSnapshot5.getString("Gender") != null && documentSnapshot5.get("Images") != null && !documentSnapshot5.getId().equals(user.getUid())) {
                                age = (long) documentSnapshot5.get("age");
                                userGender = documentSnapshot5.getString("Gender");
                                userPhotos = (ArrayList<String>) documentSnapshot5.get("Images");

                                Location locationNew = new Location(documentSnapshot5.getId());
                                locationNew.setLatitude(geoPoint.getLatitude());
                                locationNew.setLongitude(geoPoint.getLongitude());

                                distanceM = location.distanceTo(locationNew);
                                distanceKM = (int) Math.round(distanceM / 1000);


                                if (age >= ageRangeFrom && age <= ageRangeTo && interestInGender.equals("Women") && userGender.equals("Woman")) {
                                    db.collection("UsersFilter").document(user.getUid()).update("UsersInRange", FieldValue.arrayUnion(new User(documentSnapshot5.getString("Name"), age, userPhotos.get(0), documentSnapshot5.getId(), distanceKM, null)));
                                } else if (age >= ageRangeFrom && age <= ageRangeTo && interestInGender.equals("Men") && userGender.equals("Man")) {
                                    db.collection("UsersFilter").document(user.getUid()).update("UsersInRange", FieldValue.arrayUnion(new User(documentSnapshot5.getString("Name"), age, userPhotos.get(0), documentSnapshot5.getId(), distanceKM, null)));
                                } else if (age >= ageRangeFrom && age <= ageRangeTo && interestInGender.equals("Everyone")) {
