Android SQLite数据库中的ListView错误

我有个问题，不知道该怎么办。我试图从SQLite数据库创建ListView，但应用程序在数据库中导致错误。我试过几种方法，但都不管用。需要注意的一点是，该应用程序在我的智能手机（Android 4.4.4）上运行良好，但在该版本的其他不同版本中会出现错误。 如果您能将此信息发送给我，我将不胜感激

引发的异常为

原因：android.database.sqlite.SQLiteException:无此表： medidas（代码1）：，编译时：从medidas中选择*，其中 id_usuario=

因此，您的“medidas”表不存在。因此，请确认调用了

onCreate

，并且调用了

db.execSQL（CREATE\u MEDIDAS）

此外：

   db.execSQL("DROP TABLE IF EXISTS " + CREATE_USUARIO);
   db.execSQL("DROP TABLE IF EXISTS " + CREATE_MEDIDAS);

它应该是表的名称，而不是整个create语句

另外请注意，SQLite没有十进制，它将是一个真正的

，那么当您遍历代码时会发生什么呢？特别是在DB.onCreate？谢谢你的回答。我做了你告诉我的所有更改，但仍然是相同的错误。
