Question

我一直在使用Login-Register应用程序，目前正面临一些问题。

我遇到的问题是，即使我能够输入信息并点击＆＃34;注册＆＃34;按钮。
每当我按下＆＃34;登录＆＃34;按钮，应用程序将始终显示＆＃34;不幸的是，此应用程序已停止＆＃34;。

有谁知道为什么并可以提供帮助？
我希望尽快得到帮助，因为我正在为我的最后一年项目做这件事。

Answer 1

在Information.java文件中，emergencycontactnumber的Setter方法不正确，

public void setEmergencycontactnumber (String emergencycontactnumber){
    this.name = emergencycontactnumber;
}

虽然应该

public void setEmergencycontactnumber (String emergencycontactnumber){
    this.emergencycontactnumber= emergencycontactnumber;
}

这里发生的是，emergencycontactnumber总是null因为你没有设置它，所以在将数据插入sqlite时会抛出错误，因为在你的create table查询中，你指定了{{1 ，导致错误，您的数据永远不会存在。

没有信息存储在SQLite数据库
