1、TextView 显示 Html 类解析的网页
CharSequence richText = Html.fromHtml("<strong>萝卜白菜的博客</strong>--<a href='http://orgcent.com'>http://orgcent.com</a>"); mTVText.setText(richText); // 此行必须,否则超链接无法点击,ScrollingMovementMethod 实现滚动条 mTVText.setMovementMethod(LinkMovementMethod.getInstance());
PS:如果想同时让内容可滚动和超链接可点击,只要设置 LinkMovementMethod 即可,因为其继承了 ScrollingMovementMethod。
2、TextView 显示 Html 解析的图片和自定义标签
final String html = "萝卜白菜的博客<img src='http://m3.img.libdd.com/farm3/115/BBE681F0CAFB16C6806E6AEC1E82D673_64_64.jpg'/><mytag color='blue'>自定义 </mytag>"; // 处理未知标签,通常是系统默认不能处理的标签 final Html.TagHandler tagHandler = new Html.TagHandler() { int contentIndex = 0; /** * opening : 是否为开始标签 * tag: 标签名称 * output:输出信息,用来保存处理后的信息 * xmlReader: 读取当前标签的信息,如属性等 */ public void handleTag(boolean opening, String tag, Editable output, XMLReader xmlReader) { if ("mytag".equals(tag)) { if (opening) { // 获取当前标签的内容开始位置 contentIndex = output.length(); try { final String color = (String) xmlReader.getProperty("color"); } catch (Exception e) { e.printStackTrace(); } } else { final int length = output.length(); String content = output.subSequence(contentIndex, length).toString(); SpannableString spanStr = new SpannableString(content); spanStr.setSpan(new ForegroundColorSpan(Color.GREEN), 0, content.length(), Spannable.SPAN_INCLUSIVE_EXCLUSIVE); output.replace(contentIndex, length, spanStr); } } System.out.println("opening:" + opening + ",tag:" + tag + ",output:" + output); }}; // 解析图片 final Html.ImageGetter imageGetter = new Html.ImageGetter() { public Drawable getDrawable(String source) { // 在此必须异步加载图片 Drawable d = null; try { InputStream is = new DefaultHttpClient().execute(new HttpGet(source)).getEntity().getContent(); Bitmap bm = BitmapFactory.decodeStream(is); d = new BitmapDrawable(bm); // setBounds(0, 0, bm.getWidth(), bm.getHeight()); d.setBounds(0, 0, 200, 300); } catch (Exception e) { e.printStackTrace(); } return d; } }; } richText = Html.fromHtml(html, imageGetter, tagHandler); mTVText.setText(richText);
