问题描述

我知道，对此有很多问题，但是没有答案帮助了我.
试图从一个著名的乌克兰门户网站解析足球新闻，并放在我的列表视图中.

I know, there are a lot of questions on this, but no answer helped me.
Trying to parse football news from one famous ukrainian portal and put to my listview.

我解析了新闻提要"类:

I parsed "news-feed" class:

 class ParseTitle extends AsyncTask<Void, Void, HashMap<String, String>>{

    @Override
    protected HashMap<String, String> doInBackground(Void... params) {
        HashMap<String, String> hashMap = new HashMap<>();

        try {
            Document document = Jsoup.connect("http://football.ua/england.html").get();
            Elements elements = document.select(".news-feed");

            for (Element element : elements){
                Element element1 = element.select("a[href]").first();
                hashMap.put(element.text(), element1.attr("abs:ahref"));
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
        return hashMap;
    }
}

推荐答案

使用

Elements elements = document.select("article.news-feed");

代替

Elements elements = document.select(".news-feed");

将我的代码与您的代码进行比较，我看到了很大的不同，首先，我认为更重要的是，您将读取值存储在HashMap中，而我则存储在StringBuffer中.然后，我连接并按照这种方式进行:

comparing my code to yours, I see good differences, firstly and I think more important, you accumulate the read values in a HashMap, I in a StringBuffer. Then I connect and go this way:

try {

doc = Jsoup.connect("http://football.ua/england.html").userAgent("yourPersonalizedUA").timeout(0).ignoreHttpErrors(true).get();
topicList = doc.select("article.news-feed");

for (Element topic : topicList) {
    myString += topic.html();
}} catch (IOException e) { System.out.println("io - "+e); }

buffer.append(myString);

然后，如果一切正常

return buffer.toString();

假设您已经在开始时说过:

Presuming you've already stated at the beggining:

private Document doc;
private String myString;
private StringBuffer buffer;
private Elements topicList;

不确定是否有帮助，也许可以带来新的视角.您是否成功使用代码解析了另一个页面?

Not shure if this helps, maybe can lead into a new perspective. Have you succeeded parsing another page with your code?
