OPEN HOUSE SCHEDULED AT CLARK-SHAW

</td>

<p><span style="font-size: 12pt;">January 16, 2013 - Due to the relocation of Murphy High School to the Clark-Shaw campus and the necessary construction that is still ongoing, Clark-Shaw school did not participate in the magnet school &ldquo;See and Sign&rdquo; January 11 and 12<sup>th</sup>. We would like to resume giving school tours and meeting interested parents. Therefore, we are planning an &ldquo;Open House&rdquo; on Friday, January 25 from 9:00 a.m.- 12:00 p.m. to coincide with our school&rsquo;s Science Fair Open House that is scheduled for that day.</span></p>

我想在android应用程序中表示文本，如下所示：

*计划在CLARK-SHAW举行的开放日

2013年1月16日-由于墨菲高中搬迁到克拉克-肖校区，必要的建设仍在进行中，克拉克-肖学校没有参加磁铁学校的“见并签署”1月11日和12日。我们希望恢复提供学校参观和会见感兴趣的家长。因此，我们计划在1月25日(星期五)上午9:00 -下午12:00举行“开放参观”。恰逢我校定于当天举行的科学博览会开放日。

请与您的朋友和邻居分享此信息。磁石学校申请现已在线提供。*

我怎样才能在android中获得它。

Answer 1

使用jsoup http://jsoup.org/，您可以获得以下内容

下载jsoup.jar文件，然后将其添加到您的libs文件夹中，然后转到安卓依赖项，右键单击>> build path >> configure build path >> add JARS>> libs >>，然后选择您下载的jsoup.jar文件

 try {
      String website="http://www.mcpss.com/?PN='News2'&SubP='DNewsStory'&gn=&NewsID=47318&ShowNav=&StoryGroup=Current";
      Document doc = Jsoup.connect(website).get();
      Elements el=doc.getElementsByClass("header");
      String text=el.text();
    } catch (Exception e) {
        Log.wtf("name of activity","error message to show in log", e);
    }

Answer 2

由于这是一个超文本标记语言文档，请尝试对TextView使用Html.fromHtml(字符串)，或者尝试使用webview取决于标签。

对于TextView，您可以像这样使用

TextView txt=new TextView(getApplicationContext());
        String str="<td class=\"header\">"+
        "OPEN HOUSE SCHEDULED AT CLARK-SHAW"+
        "</td>"+
        "<p><span style=\"font-size: 12pt;\">January 16, 2013 - Due to the relocation of Murphy High School to the Clark-Shaw campus and the necessary construction that is still ongoing, Clark-Shaw school did not participate in the magnet school &ldquo;See and Sign&rdquo; January 11 and 12<sup>th</sup>. We would like to resume giving school tours and meeting interested parents. Therefore, we are planning an &ldquo;Open House&rdquo; on Friday, January 25 from 9:00 a.m.- 12:00 p.m. to coincide with our school&rsquo;s Science Fair Open House that is scheduled for that day.</span></p>"+
        "<p><span style=\"font-size: 12pt;\">&nbsp;</span></p>"+
        "<p><span style=\"font-size: 12pt;\">Please share this information with your friends and neighbors.&nbsp;&nbsp; Magnet School applications are available now online.</span></p>"+
        "<p>&nbsp;</p>";

        txt.setText(Html.fromHtml(str));

对于WebView，尝试使用webview.loadData()；
