该App已经上传到百度应用市场：http://shouji.baidu.com/soft/item?docid=8928185&from=as&f=search_app_it%E8%B5%84%E8%AE%AF%40list_1_image%402%40header_all_input

有兴趣的可以下载看看。接下来我会公布源代码，不过该App并没有使用代码混淆，所以可以通过反编译清楚的看到源码。

首先是封装的对象：

public class NewsDto {
    private List<News>newses;
    private String nextPage;

    public List<News> getNewses(){
        return newses;
    }

    public String getNextPage() {
        return nextPage;
    }

    public void setNextPage(String nextPage) {
        this.nextPage = nextPage;
    }

    public void setNewses(List<News> newses) {
        this.newses = newses;
    }
}

public class News {
    /*
    标题
     */
    private String title;
    /**
     * 摘要
     */
    private String sumary;
    /**
     * 内容
     */
    private String content;
    /**
     * 图片链接
     */
    private String imageLink;
    /**
     * 类型
     */
    private int type;
    /**
     * 上一篇
     */
    private String prevPassage;
    /**
     * 上一篇的url
     */
    private String prevUrl;
    /**
     * 下一篇
     */
    private String nextPassage;
    /**
     * 下一篇的url
     */
    private String nextUrl;
    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }

    public String getSumary() {
        return sumary;
    }

    public void setSumary(String sumary) {
        this.sumary = sumary;
    }

    public String getContent() {
        return content;
    }

    public void setContent(String content) {
        this.content = content;
    }

    public String getImageLink() {
        return imageLink;
    }

    public void setImageLink(String imageLink) {
        this.imageLink = imageLink;
    }

    public int getType() {
        return type;
    }

    public void setType(int type) {
        this.type = type;
    }

    public String getPrevPassage() {
        return prevPassage;
    }
    public void setPrevPassage(String prevPassage) {
        this.prevPassage = prevPassage;
    }

    public String getNextPassage() {
        return nextPassage;
    }

    public void setNextPassage(String nextPassage) {
        this.nextPassage = nextPassage;
    }

    public String getPrevUrl() {
        return prevUrl;
    }

    public void setPrevUrl(String prevUrl) {
        this.prevUrl = prevUrl;
    }

    public String getNextUrl() {
        return nextUrl;
    }

    public void setNextUrl(String nextUrl) {
        this.nextUrl = nextUrl;
    }
}

添加了一个新的业务方法，把html字符串转化为List对象：

一：CSDN

public NewsDto getNews(String urlStr) throws CommonExecption {
    NewsDto newsDto = new NewsDto();
    List<News> newses = new ArrayList<>();
    String htmlStr = DataUtil.doGet(urlStr, "UTF-8");
    Document doc = Jsoup.parse(htmlStr);

    // 获得文章中的第一个detail
//    System.out.println(htmlStr);
    Element detailEle = doc.select(".left .detail").get(0);
    // 标题
    Element titleEle = detailEle.select("h1.title").get(0);
    News news = new News();
    String title = titleEle.text();
    title = AppUtil.encoding(title,"utf-8");
    news.setTitle(title);
    news.setType(Constant.TITLE);
    newses.add(news);
    // 摘要
    Element summaryEle = detailEle.select("div.summary").get(0);
    news = new News();
    String summary = summaryEle.text();
    summary = AppUtil.encoding(summary,"utf-8");
    news.setSumary(summary);
    news.setType(Constant.SUMMARY);
    newses.add(news);
    // 内容
    Element contentEle = detailEle.select("div.con.news_content").get(0);
    Elements childrenEle = contentEle.children();

    for (Element child : childrenEle) {
        Elements imgEles = child.getElementsByTag("img");
        // 图片
        if (imgEles.size() > 0) {
            for (Element imgEle : imgEles) {
                if (imgEle.attr("src").equals(""))
                    continue;
                news = new News();
                String imgLink = imgEle.attr("src");
                imgLink = AppUtil.encoding(imgLink,"utf-8");
                news.setImageLink(imgLink);
                news.setType(Constant.IMG);
                newses.add(news);
            }
        }
        // 移除图片
        imgEles.remove();

        if (child.text().equals(""))
            continue;

        news = new News();
        news.setType(Constant.CONTENT);

        try {
            if (child.children().size() == 1) {
                Element cc = child.child(0);
                if (cc.tagName().equals("b")) {
                    news.setType(Constant.BOLD_TITLE);
                }
            }

        } catch (IndexOutOfBoundsException e) {
            e.printStackTrace();
        }
        String content = child.outerHtml();
        content = AppUtil.encoding(content,"utf-8");
        news.setContent(content);
        newses.add(news);
    }
    newsDto.setNewses(newses);
    return newsDto;

上一教程已经完成了Xlist的显示，上拉与下拉，现在给它添加OnItemClickListener:

mXlistView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        NewsItem newsItem = mDatas.get(position-1);
        NewsItem nextItem=mDatas.get(position);
        Intent intent=null;
        if (newTypes_iteye==17){
            intent = new Intent(getActivity(), SubjectsActivity.class);
            intent.putExtra("url", newsItem.getLink());
        }else {
            intent = new Intent(getActivity(), NewsContentActivity.class);
            intent.putExtra("url", newsItem.getLink());
            intent.putExtra("nextUrl", nextItem.getLink());
            intent.putExtra("select", select);
            intent.putExtra("cuttenrPage", currentPage);
        }
        startActivity(intent);
    }
});

到达显示内容的Activity页面：
