将数据从列表视图（从 Rest Api 生成）传递到另一个活动并将其保存到 SQLite 数据库中

【中文标题】将数据从列表视图（从 Rest Api 生成）传递到另一个活动并将其保存到 SQLite 数据库中【英文标题】：pass Data from a List View (generated from Rest Api) to another activity and save that into SQLite Database 【发布时间】：2016-11-01 15:24:11 【问题描述】：我正在使用 REST api 通过 XML 提要从 Job 站点创建一个 android 应用程序（仍然是基本结构，没有任何设计）。
到目前为止，我可以设法解析 XML 数据，在每行显示带有 POP UP 菜单项的列表视图。我将数据从 PostBaseAdapter 传递给 MarkAsFav 类。你能告诉我我做得对吗？因为，我没有在数据库中保存任何数据 现在，我有一个问题：
我有 3 个弹出菜单项： 1.设置为收藏 2. 在脸书上分享 3. 发邮件给你的朋友
我正在处理第 1 点。
现在，我会将数据保存在 SQLite 数据库本身中。因此，我将所有数据（有关所有行的作业的所有详细信息）传递给另一个活动，此外，我接受用户名以通过 insertDB() 在我的数据库中保存详细信息。
但是，不幸的是，数据库中没有保存任何内容。 你能告诉我，数据是否通过，数据是否保存在数据库中？
请帮帮我。请告诉我在哪里以及如何修改代码？

【问题讨论】：
代码太多了。制作最小的可重现示例。从固定字符串中获取数据并将其传递给 SQL @sixtytrees 感谢您的回复。您能否检查 PostDatabase 类和 MarkAsFab 类和 DBHelper 类，让我知道我是否做得对。我仍然没有在数据库中保存任何数据。 【参考方案1】：我刚刚更新了我的代码，它对我来说工作正常。我把它贴在这里，以便任何人都可以在需要时使用。
