抱怨道歉，但我认为我看到了根本问题。
AFAICT，当数据库版本号为CHANGED或db不存在时，SQLiteOpenHelper中的onCreate仅对一个DBHelper类调用ON ON ONCE;不会为每个单独的类调用它，只是为了调用第一个类。从而创建第一个表而不是其他表。
一个（不推荐并且不确定它是否有效）修复将把每个表放在不同的数据库中，然后在你的sql中使用 dbname.tablename 来访问它们。
从您的代码中，我对您希望采用的整体设计模式有点不确定，因此其余部分可能有点偏离主题：
如果你想“根据需要”创建表，那么如果你输入SQL来检查表是否存在可能会更好。如果没有，就创建它。 （效率低但可靠）
/** does table exist? **/
private boolean txists(SQLiteDatabase db, String tableName) {
Cursor cursor = db.rawQuery("select DISTINCT tbl_name from sqlite_master where tbl_name = '" + tableName + "'", null);
if (cursor != null) {
if (cursor.getCount() > 0) {
cursor.close();
return true;
}
cursor.close();
}
return false;
}
除了我读过的所有内容之外，各种DBHelpers的模式似乎是单身
private static MYDBHelper dbhelper = null;
public MYDBHelper getDBHelper(){
if( dbhelper == null ){
dbhelper = newInstance(...);
...
}
return dbhelper;
}
如果您正在尝试实现“可插拔”架构，请在每个类中封装表规范和创建;认为在每个插件类（AddAchievements＆amp; AddStats）中使用单个DBHelper类而不是一个dbhelper的接口和挂钩。
最后，您可能想要将ContentProvider视为访问数据的一种方式（是的，我知道它看起来像一个不必要的抽象和复杂层，但是当您扩展和扩展您的功能时它是有意义的应用程序，特别是在与其他服务交谈时，添加搜索，通知等;它还提供了一个集中的位置来存放您的DBHelper，表创建等。）

我可能会失明，但在我的模拟器中找不到“擦除用户数据”以检查其工作原理。
签入DDMS文件资源管理器目录/data/data/your.app.name/databases 从那里删除所有文件并再次运行应用程序。
您的表格的名称全部为小写字母，但如果您收到错误，则使用首字母大写。 为表名创建常量，就像使用列一样，并使用它们来避免混淆
//修改
您现在提供的代码与之前完全不同，而且这个代码无法正常工作。 DBHelper是一个并且对于所有表都是通用的，但是你为每个表分开了它。 因此，您只有一个表用户，因为这是您首先访问的表。
如果你希望将所有表保存在不同的类中，你必须将DbHelper类分开，而不是每个类的内部类。
