android - 编译时由: android. database.sqlite.SQLiteException : near "org": syntax error (code 1): ,引起:

Question

我正在尝试使用 kotlin 中的 anko 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))
}

当我将 AUTOINCREMENT 添加到 ID 时出现以下错误。它在没有 AUTOINCREMENT 的情况下工作。使用 anko 库将任何属性设置为 AUTOINCREMENT 的方法是什么。

看来您使用的是过时版本的 Anko。在 0.10 版本中，连接修饰符的问题已得到修复，并在 0.10.1 版本中再次恢复。

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。由于它没有定义 toString() 方法，因此使用实例的 Java 表示。

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

如果最新的修复与您无关，请使用版本 0.10。
