如何从网站传输数据和资源
这是非常天真的......但是如何从网站传输某些信息。据我了解，webview 会启动一个网页，但是如果我只想流式传输网站上发布的段落怎么办？
示例：雅虎！ Fantasy Football...有关球员的最新动态以及有关他们的新闻提要。
这显然比我的问题复杂得多。我对可以引导我完成此操作的教程感兴趣。这是否也需要在服务器端编程才能将其发送出去？先感谢您。
This is very naive... but how do you stream certain bits of information from a website. From what I understand webview launches a web page, but what if I want to only stream a paragraph that was published on a site.
Example: Yahoo! Fantasy Football... Updates on players and the news feed about them.
This is obviously a lot more complicated than my question. I would be interested in a tutorial that could walk me through this. Does this also take programming on the server side to send this out? Thank you in advance.

如果网站有一个 API，其中的数据以易于在应用程序中使用的格式（例如 JSON 或 XML）提供，那么您应该能够通过 HTTP 获取数据，然后解析它并使用它在您的应用程序中。这可能是一个相当不错的起点： http:// developer.android.com/reference/org/apache/http/client/HttpClient.html
If the site has an API where their data is available in a easy-to-use-in-an-application format, such as JSON or XML, then you should be able to just get the data over HTTP and then parse it and use it in your application. This might be a reasonably good place to start: http://developer.android.com/reference/org/apache/http/client/HttpClient.html
您可以打开一个 文件流 并下载整个 html 文件，然后使用 SAX 解析它，直到您找到所需的数据并显示它。唯一的问题是，如果他们更改网站，可能会破坏您的应用程序。
You could open up a file stream and download the entire html file then parse through it with SAX till you find the data you want and display it. Only problem with this is if they change there website it could break your app.
