值得注意的是，如果您试图在Service Stack项目中完成此操作，那么它已经是一个内置的字符串扩展

using ServiceStack.Text;
// ...
"The <b>quick</b> brown <p> fox </p> jumps over the lazy dog".StripHtml();

有时html字符串来自xml，带有这样的&lt。在使用Jsoup时，我们需要解析它，然后清理它。

Document doc = Jsoup.parse(htmlstrl);
Whitelist wl = Whitelist.none();
String plain = Jsoup.clean(doc.text(), wl);

而仅使用Jsoup.parse(htmlstrl).text()不能删除标签。

使用Html.fromHtml

HTML标签是

<a href=”…”> <b>,  <big>, <blockquote>, <br>, <cite>, <dfn>
<div align=”…”>,  <em>, <font size=”…” color=”…” face=”…”>
<h1>,  <h2>, <h3>, <h4>,  <h5>, <h6>
<i>, <p>, <small>
<strike>,  <strong>, <sub>, <sup>, <tt>, <u>

根据Android的官方文档，HTML中的任何标签都将显示为一个通用的替换字符串，你的程序可以通过并替换为真正的字符串。

超文本标记语言formHtml方法接受一个Html。TagHandler和Html。ImageGetter作为参数以及要解析的文本。

例子

String Str_Html=" <p>This is about me text that the user can put into their profile</p> ";

Then

Your_TextView_Obj.setText(Html.fromHtml(Str_Html).toString());

输出

这是关于我的文本，用户可以放入他们的个人资料

这里有一个稍微更充实的更新，试图处理一些格式的休息和列表。我用Amaya的输出作为指导。

        System.out.println(convert(html));
    }
}

你可以使用这个方法从字符串中删除HTML标签，

public static String stripHtmlTags(String html) {

    return html.replaceAll("<.*?>", "");

}

在Android上试试这个:

String result = Html.fromHtml(html).toString();
