基于XMPP 、openfire 、asmack的 android 聊天客户端（2）

2 创建聊天室

/**
	 * 创建多用户聊天室
	 */
	private void createMultiUserChat() {
		if (!Sessions.isLoginOfSuccess) {
			return;
		}

		new Thread() {
			public void run() {
				try {
					Thread.sleep(1 * 1000);
				} catch (InterruptedException e) {
					e.printStackTrace();
				}

				int count = 0;
				boolean isRandom = false;

				while (count <= 10 && !create_flag) {
					count++;

					try {
						if (mHostInfo != null) {
							mUserNickName = getNickName(isRandom);
							muc = ConnectionUtils.getMultiUserChat(mHostInfo.room_id, mHostInfo.room_service, mUserNickName,  Password, ChatroomActivity.this);

							if (muc != null) {
								create_flag = true;
								// 创建聊天室成功,监听聊天室返回的消息
								// 监听消息
								muc.addMessageListener(packetListener);
								// muc.addParticipantListener(participantListener);
								muc.addParticipantStatusListener(statusListener);
								muc.addUserStatusListener(userStatusListener);
								mHandler.sendEmptyMessageDelayed(9, 500);
							} else {
								create_flag = false;
							}
						} else {
							create_flag = false;
						}
						// } else {
						//
						// }
					} catch (NotFoundException e) {
						e.printStackTrace();
					} catch (SameException e) {// 昵称重复
						isRandom = true;
					} catch (BannedException e) {// 禁止加入房间
						sendBandHandle(15);
						return;
					} catch (XMPPException e) {
						e.printStackTrace();
					} catch (Exception e) {
						e.printStackTrace();
					}
				}

				if (!create_flag) {
					android.os.Message message = mHandler.obtainMessage();
					message.what = 3;
					message.obj = getResources().getString(R.string.create_room_fail);
					message.sendToTarget();
				}
			};
		}.start();
	}

 分析下创建的过程 

主要就是创建 muc 对象

muc = ConnectionUtils.getMultiUserChat(mHostInfo.room_id, mHostInfo.room_service, mUserNickName,  Password, ChatroomActivity.this);
