我使用Firebase创建了一个Android应用，并且确实有3个按钮可以上传3个不同的图像。但是，当我提交请求时，它上传了第三张图片3次，并且在数据库中缺少某些字段。让我告诉你我做了什么：
这是用户模型：
public class CarrierUser {
public String fullname;
public String email;
public String password;
public String address;
public String city;
public String state;
public String zipcode;
public String country;
public String phone;
public String cardnumber;
public String expiredate;
public String CVC;
public String rate;
public String type;
public String profilePic;
public String idPic;
public String criminalRecordPic;
public Boolean activated;
public CarrierUser() {
}
public CarrierUser(String fullname, String email, String password, String address, String city, String state, String zipcode, String country, String phone, String cardnumber, String expiredate, String CVC, String type, String rate, String profilePic, String idPic, String criminalRecordPic, Boolean activated) {
this.fullname = fullname;
this.email = email;
this.password = password;
this.address = address;
this.city = city;
this.state = state;
this.zipcode = zipcode;
this.country = country;
this.phone = phone;
this.cardnumber = cardnumber;
this.expiredate = expiredate;
this.CVC = CVC;
this.type = type;
this.rate = rate;
this.profilePic = profilePic;
this.idPic = idPic;
this.criminalRecordPic = criminalRecordPic;
this.activated = activated;
}
}
这是注册类，我知道要阅读很多东西，但我确实需要帮助。

因为我需要上传的文件的URL，所以我认为需要声明一些变量，这些变量等于将该图像上传到数据库的函数，并使该函数返回String，这似乎是逻辑。 我认为缺少profilePic，idPic和CrimeRecordPic字段是因为该逻辑不起作用并且该函数未返回我需要的字符串，但是问题是，如何获得这些URL？
如果您能帮助我，我将不胜感激！谢谢！
