Android Sqlite数据库-约束失败

我在sqlite数据库中插入数据时遇到问题。我在互联网上获取JSON数据，然后试图将该数据放入sqlite数据库，但这给我带来了一个约束失败错误。我知道这意味着我已经插入了相同的数据，或者至少使用了相同的id，但是当我从emulator查看我的数据库时，该表是空的，并且没有数据。下面是我正在使用的代码：

public boolean executeInsert() {
    UserDatabaseHelper userDbHelper = new UserDatabaseHelper(context, null, 1);
    userDbHelper.initialize(context);
    ContentValues values = new ContentValues();
    values.put("objectId", objectId);
    Log.i("objectd Id ", "object ID : " + objectId);
    values.put("objectOid", objectOid);
    Log.i("objectd Oid ", "object OID : " + objectOid);

    try {
        String jsonData = new String(collectionBuffer, "UTF-8");
        Log.w("JSONDATA", "JSONDATA VALID OR NOT : " + jsonData);

    }
    return true;
}

UserDbHelper类是我的数据库助手类。我正在使用它将数据放入sqlite。我对其他桌子没有任何问题。我可以用类似的代码将数据放在它们上面，但集合表不想工作

那么，有什么建议/帮助或其他可以帮助我解决问题的东西吗？

谢谢

正如我们所知，Sqlite是数据库的轻量级版本，可在多个移动平台上使用。因为它不是一个成熟的RDBMS，所以它支持一些数据类型，而不是所有数据类型

请检查是否正确插入了数据。

有几件事可能引发此异常。我认为您首先需要检查是否插入了所有非空行，以便确保插入了所有绑定行。

实际上这就是问题所在……感谢您的帮助/建议
