如何从listview中删除html标签？

与提供的description关键文字一样，Html.fromHtml支持所有html标记。

要在TextView中显示html格式的文本，请使用Html.fromHtml：

String strDes=Html.fromHtml(description).toString();

请找到以下解决方案

您可以尝试以下操作，在包中创建类并将其命名为“Util”

public class Util{
public static String stripHtml(String html) 
{
  //html = "<p sapn = 'div'>hhhhhhhhh<p> Hello World </p></span>";
  while(html.contains("<"))
    html = html.replace(html.substring(html.indexOf("<"),html.indexOf(">")+1),"");
  return html;//will return hhhhhhhh Hello World
}
}

此方法将搜索以“＆lt;”开头的任何文本并以“＆gt;”结尾它将取代它。

然后您可以在任何地方使用该方法

String myNewStringWithoutHTML = Util.stripHtml(STRING);

希望以上解决方案能为您提供帮助。

请告诉我是否需要更多帮助。我在这一方面也是如此。
