Android removes the img tag in rich text (html code)

/ / Determine whether the img tag is contained in the string
if (!TextUtils.isEmpty(content) && content.indexOf("<img") != -1) {
//img tag regular
      String regEx_img = "<img.*src\\s*=\\s*(.*?)[^>]*?>";
      Pattern p_image = Pattern.compile(regEx_img, Pattern.CASE_INSENSITIVE);
      Matcher m_image = p_image.matcher(content);
/ / Loop to remove the img tag
      while (m_image.find()) {
            String group = m_image.group();
            Log.e("fhxx", "html--->" + group);
            content = content.replace(group, "");
            Log.e("fhxx", "Interception--->" + content);
         }
      }    
 textview.setText(Html.fromHtml(content));
