android - 引起原因:android.database.sqlite.SQLiteException:靠近 “org”:语法错误(代码1):，而在编译时:

我正在尝试使用anko中的kotlin库创建表，如下所示

override fun onCreate(db: SQLiteDatabase?) {
    db!!.createTable(PersonTable.Name, true,
            Pair(PersonTable.ID, INTEGER + PRIMARY_KEY + AUTOINCREMENT),
            Pair(PersonTable.PersonName, TEXT),
            Pair(PersonTable.Domain, TEXT),
            Pair(PersonTable.MobileNumber, REAL))
}

将AUTOINCREMENT添加到ID时出现以下错误。它无需AUTOINCREMENT即可工作。使用AUTOINCREMENT库将任何属性设置为anko的方法是什么。

最佳答案

您似乎正在使用过时的Anko版本。在0.10版中，修正了串联修饰符的问题，并在0.10.1版中再次恢复。

在代码的相关部分之前是"$modifier $m"，其中$m是修饰符的字符串表示形式。由于未定义toString()方法，因此使用实例的Java表示形式。

修复后，代码为"$modifiers ${m.modifier}"。这里${m.modifier}实际上是一个字符串。

如果最新的修补程序与您不相关，请使用0.10版。
