我从 API 获取数据，然后将该数据插入 SQLite 数据库。但是当我插入该数据时，出现了一些问题。我无法找出那个问题。我正在从 API 获取正确的数据。没有问题。唯一的问题是将数据插入数据库。

我的 Json 数据格式是：

{"sku":"T_010","product_id":"7","name":"footaball","thumbnail_image":" http://www.keyss.in/pos/magento/media/catalog/product/ no_selection ","description":null,"short_description":null,"weight":"0.0000","created_at":"2013-01-15 07:00:36","updated_at":"2013-01-15 07:00:36","price":"13.0000","special_price":null,"tax_class_id":"1","cat_id":["4","15"],"cat_name":{"4 ":"手机和配件","15":"运动健身"}},

我在哪里做错了，请指导我。

任何帮助都会得到帮助。

编辑：我认为问题出在 josn 数据格式上，我得到"cat_id":["4","15"],"cat_name":{"4":"Mobile & Accessories","15":"Sports Fitness"}}，我们如何在 json 中解析它，因为它就像数组中的数组。logcat 还在02-05 12:31:39.601 给出错误：I/Database(274): sqlite returned: error code = 1, msg = table tbProductDetails has no column named cat_id

如何处理此类问题

我认为这是您的问题，您缺少一个空格。

代替 ：

database.in.DatabaseAndTableNames.PRODUCT_DISCRIPTION_COLUMN+"TEXT,"

尝试

database.in.DatabaseAndTableNames.PRODUCT_DISCRIPTION_COLUMN+" TEXT,"

在此处发布您的创建语句。验证并确保您添加了 cat_id 列和特定的数据类型。
