我必须启动一个使用 1 个数据库表（ABezoe）的应用程序我想向数据库添加一个额外的表（ABezur）
我试图让一个类与 ABezoe 类相似，但我得到一个错误，它无法找到第二个（ABezur）表，所以我无法写入它
所以互联网上的搜索告诉我我需要一个类（ADbAdapter）来创建我的数据库，并且为我想要连接到的不同表（ABezoeAdapter，ABezurAdapter）有不同的类会很好
我已尽一切努力尝试此设置，但仍然无法正常工作
我什至删除了应用程序以重新安装所有内容，但仍然没有调用数据库的 oncreate()
谁能帮我？
logcat 显示：

除此之外，在 logcat 中没有什么特别的
