android 去掉富文本（html代码）中的img标签

//判断string中是否包含img标签
if (!TextUtils.isEmpty(content) && content.indexOf("<img") != -1) {
//img标签正则
      String regEx_img = "<img.*src\\s*=\\s*(.*?)[^>]*?>";
      Pattern p_image = Pattern.compile(regEx_img, Pattern.CASE_INSENSITIVE);
      Matcher m_image = p_image.matcher(content);
//循环去掉img标签
      while (m_image.find()) {
            String group = m_image.group();
            Log.e("fhxx", "html--->" + group);
            content = content.replace(group, "");
            Log.e("fhxx", "截取--->" + content);
         }
      }    
 textview.setText(Html.fromHtml(content));
