实现方法：
复制代码代码如下:
TextView content = (TextView) convertView.findViewById(R.id.content);
content.setText(Html.fromHtml("<html><head>"+temp.get(position).getContent()+"</html></head>"));
CharSequence str = content.getText();
SpannableString spann = WeiboUtils.formatContentNoClick(str);
content.setText(spann);
具体的封装如下：
