如何将星级插入到firebase

Question

I have the following code and I can only get it to work logically if I set the star rating to hidden first and then let the user rate the star after they have given the review. I am not sure how it works but the rating of the star only gets inserted into the database if the user click on the star. I tried to put this under the setOnClickListener for my button, so that the rating score should be sent together with the review but it doesn't work. I have to do this outside my button....

add_review_button.setOnClickListener(new View.OnClickListener() {

    @Override
    public void onClick(View v) {

        final DatabaseReference reference = FirebaseDatabase.getInstance("https://medical-review-in-australia.firebaseio.com/").getReference();
        reference.addValueEventListener(new ValueEventListener() {


            public void onDataChange(@NonNull DataSnapshot snapshot) {
                for (DataSnapshot childSnapshot : snapshot.getChildren()) {

                    String clinic_info = String.valueOf(childSnapshot.child("Name").getValue());
                    final String txt_review = review.getText().toString().trim();
                    String txt_dorevitch = dorevitch.getText().toString().trim();
                    String txt_skin_cancer = skin_cancer_check.getText().toString().trim();
                    String txt_ear_suctioning = ear_suctioning.getText().toString().trim();
                    String user_email = user.getText().toString().trim();
                    String user_email2 = Objects.requireNonNull(FirebaseAuth.getInstance().getCurrentUser()).getEmail();
                    String other = others.getText().toString().trim();
                    String input = input_others.getText().toString().trim();

                    //   replace(":" ,"");
                    //    message[0] = message[0].replaceAll("[0-9]" ,"");
                    //   message[0] = message[0].replace("Shop" ,"");
                    //   if (clinic_info.equals(message[0]) && !user_email.isEmpty() && user_email.equals(user_email2) && !txt_review.isEmpty()) {
                        user_email = user_email.split("\\s*@\\s*")[0];
                        final HashMap<String, Object> map = new HashMap<>();
                        map.put("Review by " + user_email, txt_review);
                        FirebaseDatabase.getInstance("https://medical-review-in-australia.firebaseio.com/").getReference().child(message[0]).child("Reviews").updateChildren(map);
                        // rating bar code

                        ratingbar.setVisibility(View.VISIBLE);
                        final String finalUser_email = user_email;
                        ratingbar.setOnRatingBarChangeListener(new RatingBar.OnRatingBarChangeListener() {

                            @Override
                            public void onRatingChanged(RatingBar ratingBar, float rating, boolean fromUser) {
                                int rate = (int) rating;
                                String info = null;

                                myRating = (int) ratingBar.getRating();

                                switch (rate) {
                                    case 1:
                                        info = "Sorry to hear that! :( ";
                                        break;
                                    case 2:
                                        info = "We always accept suggestions!";
                                        break;
                                    case 3:
                                        info = "Good enough!";

                                    case 4:
                                        info = "Great! Thanks you!";
                                        break;
                                    case 5:
                                        info = "Awesome! You are the best!";
                                        break;
                                }

                                Toast.makeText(Add_Review.this, info, Toast.LENGTH_SHORT).show();


                                HashMap<String, Object> map5 = new HashMap<>();
                                map5.put("Rating by " + finalUser_email, rate);



                                Toast.makeText(Add_Review.this, "Review Successfully Submited", Toast.LENGTH_SHORT).show();

Answer 1

I think the reason your rating is saved only when user clicks the star is because the updateChildren code is inside the onRatingChangeListener.

Is is not working if you keep updateChildren command outside the the onRatingChangeListener and inside the review button onClickListener?

Also try this :

1. Keep the onRatingChangeListener outside the review Button;s OnclickListener.

2. Declare the info variable as public so that it can be used in both functions ie OnRatingChangeListener ( which will save rating in the info variable ) and then the button's OnclickListener ( which will save the rating to database using info variable)
