CharSequence richText = Html.fromHtml("<strong>蘿卜白菜的博客</strong>--<a );
mTVText.setText(richText);
//此行必須，否則超鏈接無法點擊,ScrollingMovementMethod實現(xiàn)滾動條
mTVText.setMovementMethod(LinkMovementMethod.getInstance());

PS: 如果想同時讓內(nèi)容可滾動和超鏈接可點擊，只要設(shè)置LinkMovementMethod即可。因為其繼承了ScrollingMovementMethod。關(guān)于ScrollingMovementMethod說明，可查看android實現(xiàn)TextView垂直或水平滾動

2、TextView顯示Html解析的圖片和自定義標(biāo)簽

final String html = "蘿卜白菜的博客<img src='http://m3.img.libdd.com/farm3/115/BBE681F0CAFB16C6806E6AEC1E82D673_64_64.jpg'/><mytag color='blue'>自定義</mytag>";
//處理未知標(biāo)簽,通常是系統(tǒng)默認(rèn)不能處理的標(biāo)簽
final Html.TagHandler tagHandler = new Html.TagHandler() {
int contentIndex = 0;
/**
* opening : 是否為開始標(biāo)簽
* tag: 標(biāo)簽名稱
* output:輸出信息，用來保存處理后的信息
* xmlReader: 讀取當(dāng)前標(biāo)簽的信息，如屬性等
*/
public void handleTag(boolean opening, String tag, Editable output,
          XMLReader xmlReader) {
    if("mytag".equals(tag)) {
      if(opening) {//獲取當(dāng)前標(biāo)簽的內(nèi)容開始位置
        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);
}};
//解析圖片
final Html.ImageGetter imageGetter = new Html.ImageGetter() {
   public Drawable getDrawable(String source) {
      //在此必須異步加載圖片
      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);
