您必须用Java在双引号中包装字符串.单引号保留为单个字符.
编辑:你必须像这样逃避你的内部双引号:
String test = "He said \"yo\".";
这是你的字符串:
String htmldata = "<html><head><meta http-equiv=\"Content-Type\" content=\"text/html; charset=Utf-8\"><script type=\"text/javascript\" src=\"qrcode.js\"></script><!-- SJIS Support (optional) --><!--<script type=\"text/javascript\" src=\"qrcode_SJIS.js\"></script>--><script type=\"text/javascript\" src=\"sample.js\"></script><title name=\"msg\">what</title></head><body onload=\"update_qrcode()\"><form><title>whatwhatwhat</title><input type=\"hidden\" name=\"msg\" value=\"http://www.bjjbadges.com\"></input></br><center><div id=\"qr\"></div></center></form></body></html>";
