TextView是用来显示文本的，有时需要给TextView中的个别字设置为超链接，或者设置个别字的颜色、字体等，那就需要用到Spannable对象，可以借助Spannable对象实现以上设置

myTextView = (TextView) this.findViewById(R.id.myTextView);   

  //创建一个 SpannableString对象

  SpannableString sp = new SpannableString("这句话中有百度超链接,有高亮显示，这样，或者这样，还有斜体.");

  //设置超链接

  sp.setSpan(new URLSpan("http://www.baidu.com"), 5, 7,

  Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);

  //设置高亮样式一

  sp.setSpan(new BackgroundColorSpan(Color.RED), 17 ,19,Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

  //设置高亮样式二

  sp.setSpan(new ForegroundColorSpan(Color.YELLOW),20,24,Spannable.SPAN_EXCLUSIVE_INCLUSIVE);

  //设置斜体

  sp.setSpan(new StyleSpan(android.graphics.Typeface.BOLD_ITALIC), 27, 29, Spannable.SPAN_EXCLUSIVE_INCLUSIVE);

  //SpannableString对象设置给TextView

  myTextView.setText(sp);

  //设置TextView可点击

  myTextView.setMovementMethod(LinkMovementMethod.getInstance());
