Question

您好，我遇到了这个错误，我正在尝试捕获并写下用户的节点>电子邮件，但仍然出错，有人可以帮我吗？欢迎任何帮助。节点电子邮件已经有逗号，但是在恢复时，我仍然收到错误消息，我正在尝试修改节点时收到下面的代码。

我的代码

 addButton.setOnClickListener(new View.OnClickListener() {
        DatabaseReference ref = FirebaseDatabase.getInstance().getReference();
        @Override
        public void onClick(View v) {
            final FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
            final String userUid = user.getEmail();

            final DatabaseReference ref = FirebaseDatabase.getInstance().getReference();

            ref.child("users").child(user.getEmail().replace(".",",")).addListenerForSingleValueEvent(new ValueEventListener() {
                @Override
                public void onDataChange(DataSnapshot dataSnapshot) {
                    for (DataSnapshot ds : dataSnapshot.getChildren()) {


                        Map<String,Object> map = new HashMap<>();
                        map.put("cassinotime",dataSnapshot.child("cassinotime").getValue(String.class));
                        map.put("cassinoprofit",dataSnapshot.child("cassinoprofit").getValue(String.class));


                        ref.child("users").child(user.getEmail()).child("cassino").child("cassinotime").setValue(map);
                        ref.child("users").child(user.getEmail()).child("cassino").child("cassinotime").setValue("50000");
                        ref.child("users").child(user.getEmail()).child("cassino").child("cassinoprofit").setValue("250");


                    }
                }

                @Override
                public void onCancelled(DatabaseError databaseError) {

                }
            });
        }

与其将电子邮件用作用户详细信息的父节点，不如使用userId：

FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
String userId = user.getUid();
ref.child("users").child(userId).addListenerForSingleValueEvent(/* ... */);
