我正在尝试构建Android应用并设法完成它的主要目的。但是，如果他们已经在SQLite数据库之外拥有一个帐户，或者创建并注册一个帐户，我就会严重阻碍成功实现SQLite数据库以让用户登录。
这些说明的相关类和XML文件在我看来是正确的但我相信当我尝试查看Logcat并从应用程序检查注册信息时，我的SQLite查询有问题或出了什么问题用户并会显示许多我觉得难以按此速率调试的错误。
我将附加相关的类，XML文件以及它在Logcat中的内容。希望这样，我可以得到我需要的帮助，因为这严重阻止我甚至进入应用程序的主要目的。非常感谢您的帮助。谢谢。

由于
，表 reg_info 中的插入无法正常工作<强>
no column named user_password
，按照： -
table reg_info has no column named user_password (code 1): , while compiling: INSERT INTO reg_info(user_password,user_name) VALUES (?,?)
这可能是由于表格已经在您的表格中修改了创建SQL（在猜测中添加了user_password列），但由于 onCreate 的原因而未应用该表格方法被调用。
onCreate 方法在创建数据库本身时调用一次（除非在别处调用），每次应用时都不会运行运行
最快的解决方法是： -
然后重新运行App。
注意这会删除数据库，从而删除存储在数据库中的任何数据。
如果您需要保留数据，则需要在代码中的适当位置运行SQL ALTER TABLE reg_info ADD COLUMN user_password TEXT。
