删除android中的html标签

Question

我有以下 XML 提要：

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

这里我必须显示类似

的描述

触摸、点击、翻转、滑动！你不 39.just read the Books, you experience it.

在这里我处理了解析器：

   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 中：

   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...在这里如何删除 HTML 标记？请为我提供解决方案？？？

我希望显示没有 Html 标记的描述...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:

    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..请为我提供解决方案？？？如何删除这些描述中的 html 标签...

Answer 1

一种选择是添加JSoup 库，将其导入并按如下方式使用：

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

Answer 2

据我所知，您可以通过可跨接口获取数据。

试试这个：

跨度可跨度 = Html.fromHtml(arrayList.get(position).getBusinessDescription());
System.out.println("说明 value----->"+n+att_ID+"------>>"+spannable);

Answer 3

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 Html.fromHtml(data).toString() 来取回没有任何 HTML 标记的字符串。

Answer 4

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

Answer 5

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标签格式化并移除标签。

Html.fromHtml(data).toString();

Answer 6

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);

Answer 7

    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:)

//Patter to detect elements contained into "<>"
private static final Pattern REMOVE_TAGS = Pattern.compile("<.+?>");

//Method to remove the html tags contained in a String variable
public static String removeTags(String string) 
{
  //validate that at least one value contains the string
  if (string == null || string.length() == 0) 
  {
     return string;
  }
  //Function to find the matches within the chain and the pattern       
  Matcher m = REMOVE_TAGS.matcher(string);
  //replace <> element with ""
  return m.replaceAll("");
}

//Implementation of the method to eliminate html tags and place inside a Text control
this.itemView.setText(
 Html.fromHtml(
  new String(removeTags("<h1>My Title here</h1>").getBytes("ISO-8859-1"),"UTF-8")
 )
);
