设置textview中字段不同位置的颜色

<pre class="java" name="code" snippet_file_name="blog_20140423_1_985937" code_snippet_id="308356">String html= comment.getContent().trim() + "<font color=\"#a1a1a1\"> //" + comment.getReply().trim() + "</font>"; 
textView.setText(Html.fromHtml(html));

设置textview中添加本地图片

/** 文字前后添加本地图片 */
TextView helpReplayCommentTV = (TextView) findViewById(R.id.help_replay_comment_tv);
ImageGetter imageGetter = new ImageGetter()
{
      @Override
       public Drawable getDrawable(String source) {
          int id = Integer.parseInt(source);
                
          // 根据id从资源文件中获取图片对象
          Drawable d = getResources().getDrawable(id);
          //设置宽高
          d.setBounds(0, 0, AndroidUtils.dip2px(HelpActivity.this, 15),
                        AndroidUtils.dip2px(HelpActivity.this, 15));
          return d;
       }
};
        //图文混排
helpReplayCommentTV.append(Html.fromHtml(getString(R.string.help_replycomment_cotent_one)
      + "<img src=\"" 
      + R.drawable.feed_detail_comment_normal
      + "\">" 
      + getString(R.string.help_replycomment_cotent_two) 
      + "<img src=\""
      + R.drawable.comment_cancel_normal+"\">"
      + getString(R.string.help_replycomment_cotent_three), imageGetter, null));
