推荐答案

嗯，我觉得你应该看看 ContentProviders 。他们更自然地，你正在试图解决的问题。你必须要实现自定义的光标其中的ContentProvider 上一个查询请求返回。

Well I think you should look at ContentProviders. They are more natural to the problem that you are trying to solve. You have to implement your custom Cursor which ContentProvider returns on a query request.
