Answer 1

找到了两个大小写冲突的getter或字段属性：名称

您的用户 MODEL 类将是

public class User {
            private String name,password;
            private User(){
            }
            public User(String name,String password){
                name = name;
                password = password;
            }
            public String getName() {
                return name;
            }
            public void setName(String name) {
                name = name;
            }
            public String getPassword() {
                return password;
            }
            public void setPassword(String password) {
                password = password;
            }
        }

Answer 2

尝试更改

Name至name

Password至password

通常，firebase使用标准Java命名，因此您需要以小写字母开头任何变量
