如何将星级插入到firebase

Question

我有以下代码，如果我先将星级设置为隐藏，然后让用户在他们给出评论后对星级进行评分，我才能使其合乎逻辑地工作。 我不确定它是如何工作的，但只有当用户点击星星时，星星的评级才会插入到数据库中。 我试图将它放在我的按钮的 setOnClickListener 下，以便评分应该与评论一起发送，但它不起作用。 我必须在我的按钮外执行此操作....

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

                                String info = null;

                                myRating = (int) ratingBar.getRating();

                                switch (rate) {
                                    case 1:

                                }

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

我认为只有当用户单击星星时才保存您的评分的原因是因为 updateChildren 代码位于 onRatingChangeListener 中。

如果您将 updateChildren 命令保留在 onRatingChangeListener 之外和 onClickListener 审核按钮内，是否不起作用？

也试试这个：

1. 将 onRatingChangeListener 保留在评论按钮之外；s OnclickListener。

2. 将info变量声明为 public 以便它可以在两个函数中使用，即 OnRatingChangeListener （它将在info变量中保存评级），然后是按钮的 OnclickListener （它将使用info变量将评级保存到数据库中）
