我需要帮助如何使用用户模型。创建帐户而不是使用电子邮件生成父节点时。使主节点成为 uid。我尝试了一些修改但我没有成功有人可以帮助我。该帐户是由 google auth 创建的，它希望生成一个主 uid 节点而不是电子邮件。

我搜索了模型，但没有成功，如果有人可以帮助我，我将不胜感激

我仍然需要电子邮件，但不是作为主节点。对于主节点，我想要模型中已有的 uid，但我无法进行此更改:(

模型

public class User implements Serializable {
    private String user;
    private String email;
    private String photoUrl;
    private String uid;
    private String money;
    private String cassinotime;
    private  String cassinoprofit;

    public String getCassinotime() {
        return cassinotime;
    }

    public void setCassinotime(String cassinotime) {
        this.cassinotime = cassinotime;
    }

    public String getCassinoprofit() {
        return cassinoprofit;
    }

    public void setCassinoprofit(String cassinoprofit) {
        this.cassinoprofit = cassinoprofit;
    }

    public User(String user, String email, String photoUrl, String uid, String money) {
        this.user = user;
        this.email = email;
        this.photoUrl = photoUrl;
        this.uid = uid;
        this.money = money;
    }

    public User() {
    }

    public User(String user, String email, String photoUrl, String uid) {

        this.user = user;
        this.email = email;
        this.photoUrl = photoUrl;
        this.uid = uid;
    }

    public String getMoney() {
        return money;
    }

    public void setMoney(String money) {
        this.money = money;
    }

    public String getUser() {

        return user;
    }

    public void setUser(String user) {
        this.user = user;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    public String getPhotoUrl() {
        return photoUrl;
    }

    public void setPhotoUrl(String photoUrl) {
        this.photoUrl = photoUrl;
    }

    public String getUid() {
        return uid;
    }

    public void setUid(String uid) {
        this.uid = uid;
    }
}

                                    });
                        } else {

Answer 1

                       val ref = database.push().key
                        mapinfoinstance.id = ref!!
                        database.child(ref).setValue(mapinfoinstance)

'mapinfoinstance' 是我的类的一个实例。

我想你想要这样:
