如何检查 Firebase 数据是否成功将数据写入数据库（处理错误）？

因为我想设置按摩吐司，如果数据写入成功则显示按摩

reg_money.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    mAuth = FirebaseAuth.getInstance();
                    FirebaseUser userfirebase = mAuth.getInstance().getCurrentUser();


                    mDatabase = FirebaseDatabase.getInstance();
                    mDbRef = mDatabase.getReference("Student/information");
                    String email = userfirebase.getEmail();
                    Uaser_register_money user = new Uaser_register_money(namesemster, email.substring(0,11), count2);

                    mDbRef.child("Student/information").setValue(user);





                }
            });

Answer 1

只需添加监听器

   mDbRef.child("Student/information").setValue(user)
    .addOnSuccessListener(new OnSuccessListener<Void>() {
        @Override
        public void onSuccess(Void aVoid) {
            // Write was successful!
            // ...
        }
    })
    .addOnFailureListener(new OnFailureListener() {
        @Override
        public void onFailure(@NonNull Exception e) {
            // Write failed
            // ...
        }
    });
