如何从列表视图中删除html标签？

在提供的description 关键文本中，Html.fromHtml 支持所有 html 标签。

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

您可以尝试以下方法，在您的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“”结尾的任何文本并将其替换。

那么你可以在任何你想要的地方使用该方法

String myNewStringWithoutHTML = Util.stripHtml(STRING);

希望以上解决方案对您有所帮助。

如果需要我这边的更多帮助，请告诉我。
