How to retrieve 'double' values saved under one key in Firebase?

Question

I have stored Geofire coordinates in database and now I\'m trying to retrieve them using childEventListener() like this:

    mDatab         


        

Answer 1

mDatabase.child("geofire").child(key).child("l").addListenerForSingleValueEvent(new ValueEventListener() {
            @Override
            public void onDataChange(DataSnapshot dataSnapshot) {
                double latati = 0, longit = 0;
                for (DataSnapshot child : dataSnapshot.getChildren()) {
//                    Log.e("!! All Data ::> ", child.getKey()+" "+child.getValue());
                    if (child.getKey().equalsIgnoreCase("0")) {
                        latati = Double.parseDouble(String.valueOf(child.getValue()));
                    }
                    if (child.getKey().equalsIgnoreCase("1")) {
                        longit = Double.parseDouble(String.valueOf(child.getValue()));
                    }
                }
                Log.e("!_@@__Lat Long ::", latati + " " + longit);
            }

            @Override
            public void onCancelled(FirebaseError firebaseError) {
                Log.e("!!__: ", "onCancelled ", firebaseError.toException());
            }
        });
