在下面的Jsoup上尝试答案后出现异常:

使用此:

String simpleString = Html.fromHtml("your_html_string").toString();

它将根除所有html内容,并以简单的字符串返回内容。

此外,如果你想区分不同的标签/类,并且需要html中的特定文本,那么你可能需要使用一些复杂的解决方案,如JSOUP

您可以将jsoup库用于您的目的;一个简单的例子,用于阅读以下网站上呈现的HTML的段落:

 try {
            Document doc = Jsoup.connect("http://popofibo.com/pop/swaying-views-of-our-past/").get();
            Elements paragraphs = doc.select("p");
            for(Element p : paragraphs) {
              System.out.println(p.text());
            }
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } 

输出:

要将HTML作为静态内容演示,您可以轻松使用id标记的div

public static void main(String... args) {
        Document doc = Jsoup
                .parse("<html><body><div class=\"text\" id=\"editorText\" itemprop=\"text\">I want to get this Text</div></body></html>");
        Elements divs = doc.select("div#editorText");
        for (Element d : divs) {
            System.out.println(d.text());
        }
    }

<强>输出:

  

我想要这个文字

这个解决方案怎么样(不使用外部库):

public static String getContentFromHtmlPage(String page) {
    StringBuilder sb = new StringBuilder();

    try {
        URLConnection connection = new URL(page).openConnection();
        BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()));
        String line;
        while ((line = in.readLine()) != null) {
            sb.append(line);
        }
        in.close();
    } catch (IOException e) {
        // handle exception
    }

    return Html.fromHtml(sb.toString()).toString();
}
