直接当一个ｍｏｄｅｌ导入．入口是startActivity(new Intent(this, com.xmpp.xmppchat.LoginActivity.class));．要重新修改ＩＰ和端口号，比之前的ＪＡＶＡ版本，实现了语音和照片拍照等功能
7.项目的思路是：使用XMPP的发文本传一个bean过去，然后双方通过bean进行解析并且显示出来。文件，图片，视频，位置等也是同样道理，先上传服务器拿到文件相应网络地址后，把这网络地址拼在bean里面传给对方，对方收到bean,解析并且显示出来。
8.spark测试使用格式如下：{"sender_photo":"","content":"房间","doctor_photo":"","sender_nick_name":"","sender_name":"1","send_time":"11-17 11:33","parentId":0,"readed":false,"receiver_deleted":false,"receiver_id":1,"receiver_type":0,"msg_type":0,"sender_deleted":false,"sender_id":2,"msg_id":0,"is_in_time":true,"article_id":0,"sender_type":1}
