Android：SQLite数据库插入成功但重复的错误消息

时间：2014-01-03 20:09:44

标签： android sql sqlite while-loop populate

显示的代码应该从文本文件中获取数据并将其插入数据库（目前只填充了1个表，其他插入循环已被注释掉）。

pieceTable的填充发生在ManipulateDatabase构造函数内的if语句中。目前，数据库已填满（因为select语句可以从中检索数据），但LogCat在向表中插入各种字符串时会显示重复错误。

我在下面添加了LogCat输出，但由于帖子中的字符限制，必须使用PasteBin附加代码：http://pastebin.com/aR6kA3u8

非常感谢任何有关错误来源的建议。

2 个答案:

答案 0 :(得分：2)

从第597行看，您看起来正在创建一个包含两个字符串的ContentValues对象。但是，该表的架构表示您有两列，一次是另一个整数。

这就是我要开始寻找的地方。

答案 1 :(得分：0)

您的piece列定义了PRIMARY KEY约束，强制唯一性。如果要避免这些异常，则需要使用insertWithOnConflict()方法指定自定义ON CONFLICT子句。
