我遵循以下 XML 提要：

<Description>
  <p>Touch, tap, flip, slide! You don&#39;t just read Books, you experience it.</p>
</Description>

在这里我必须显示如下描述

触摸，点击，翻转，滑动！你不 39.just read the Books，你体验它。

在这里，我处理了解析器，如下所示：

   public static String removeHTML(String htmlString)
  {
  // Remove HTML tag from java String    
String noHTMLString = htmlString.replaceAll("\\<.*?\\>", "");

// Remove Carriage return from java String
noHTMLString = noHTMLString.replaceAll("\r", "<br/>");
noHTMLString = noHTMLString.replaceAll("<([bip])>.*?</\1>", "");
// Remove New line from java string and replace html break
noHTMLString = noHTMLString.replaceAll("\n", " ");
noHTMLString = noHTMLString.replaceAll("\"", "&quot;");
noHTMLString = noHTMLString.replaceAll("<(.*?)\\>"," ");//Removes all items in brackets
noHTMLString = noHTMLString.replaceAll("<(.*?)\\\n"," ");//Must be undeneath
noHTMLString = noHTMLString.replaceFirst("(.*?)\\>", " ");
noHTMLString = noHTMLString.replaceAll("&nbsp;"," ");
noHTMLString = noHTMLString.replaceAll("&amp;"," ");
return noHTMLString;

    }

在 endElement ：

   public void endElement(String uri, String localName, String qName)throws SAXException {
  currentElement = false;
   if (localName.equalsIgnoreCase("Description")){
   sitesList.setDescription(currentValue);
   String Sub_arry=n+currentValue;
   Appscontent.Sub_arraylistdes.add(Sub_arry);
   String stringWithoutHTML=removeHTML(currentValue);
   System.out.println("description value----->"+n+att_ID+"------>>"+stringWithoutHTML);}

现在我必须运行该应用程序，这意味着 html 标记与我的描述一起显示...我怎样才能删除 HTML 标记？请为我提供解决方案？？？

我希望显示没有 Html 标签的描述...请为这些提供解决方案。

编辑：

    if (localName.equalsIgnoreCase("Description")){
    sitesList.setDescription(currentValue);
    String Sub_arry=n+currentValue;
    StringBuffer sb = new StringBuffer();
    sb.append(Sub_arry);
     String newString = sb.toString();
      Appscontent.Sub_arraylistdes.add(newString);
       System.out.println("description value----->"+n+att_ID+"------>>"+newString);}

编辑：

  public static String html2text(String html) {
  return Jsoup.parse(html).text();
    }

在 endElement 中：

    if (localName.equalsIgnoreCase("Description")){
    sitesList.setDescription(currentValue);
    String Sub_arry=n+currentValue;
    Appscontent.Sub_arraylistdes.add(Sub_arry);
      String stringWithoutHTML=html2text(currentValue);
       System.out.println("description value----->"+n+att_ID+"------>>"+stringWithoutHTML);}

但我没有得到o/p ..请为我提供这些解决方案？？？我怎样才能删除这些描述中的html标签...

您可以使用 Android 中的内置 HTML 类轻松删除 Android 中的任何 HTML 标记。导入android.text.Html;. 现在，考虑到“数据”是您的具有 HTML 标记的字符串变量，您可以使用它Html.fromHtml(data).toString()来取回没有任何 HTML 标记的字符串。

删除html的简单方法。这将返回非 html 格式的文本

 private String removeHtml(String html) {
    html = html.replaceAll("<(.*?)\\>"," ");
    html = html.replaceAll("<(.*?)\\\n"," ");
    html = html.replaceFirst("(.*?)\\>", " ");
    html = html.replaceAll("&nbsp;"," ");
    html = html.replaceAll("&amp;"," ");
    return html;
}

根据html标签格式化并删除标签。

Html.fromHtml(data).toString();

一种选择是添加JSoup库，导入并使用它，如下所示：

public static String html2text(String html) {
return Jsoup.parse(html).text();
}

    private int iMobileVersion = Build.VERSION.SDK_INT;
    String strResonseTemplate = data.getStringExtra("template"); //getting HTML data in string

    if (iMobileVersion >= 24) {
                                mEtReply.setText(Html.fromHtml(strResonseTemplate, Html.FROM_HTML_MODE_COMPACT));// this code only works on and above API 24, and removes all HTML tag, but gives same view as HTML in Edittext.
                            } else {
                                mEtReply.setText(Html.fromHtml(strResonseTemplate).toString()); // bellow API level 24 we are removing only HTML tags, it will show as normal text.

                            }

希望这会有所帮助:)

据我所知，您可以通过可跨接口获取数据。

尝试使用这个：

Spanned spannable = Html.fromHtml(arrayList.get(position).getBusinessDescription());
System.out.println("描述值----->"+n+att_ID+"------>>"+spannable);

查看以下链接了解更多详情：

只需添加这几行代码即可完成。

String html=(jsonObject1.getString("originaltext"));
            html = html.replaceAll("<(.*?)\\>"," ");
            html = html.replaceAll("<(.*?)\\\n"," ");
            html = html.replaceFirst("(.*?)\\>", " ");
            html = html.replaceAll("&nbsp;"," ");
            html = html.replaceAll("&amp;"," ");
            newsModel.setNews(html);
            Log.d("originaltext: ",html);
