大家好，又见面了，我是你们的朋友全栈君。

1.思路图

2.主要功能

实现一对一聊天

实现多对多聊天

好友上线自动刷新功能

3.知识点

界面布局：一是流布局，二是卡片布局（现在应该都不用了） socket通信之对象流objectinput/outputStream 将线程里面的信息显示到界面上

4.项目代码

4.1服务端

common下有三个类：

Message.java

package com.qq.common;

public class Message implements java.io.Serializable{

	private String mesType;
	
	private String sender;
	private String getter;
	private String con;
	private String sendTime;

	public String getSender() {
		return sender;
	}

	public void setSender(String sender) {
		this.sender = sender;
	}

	public String getGetter() {
		return getter;
	}

	public void setGetter(String getter) {
		this.getter = getter;
	}

	public String getCon() {
		return con;
	}

	public void setCon(String con) {
		this.con = con;
	}

	public String getSendTime() {
		return sendTime;
	}

	public void setSendTime(String sendTime) {
		this.sendTime = sendTime;
	}

	public String getMesType() {
		return mesType;
	}

	public void setMesType(String mesType) {
		this.mesType = mesType;
	}
}

接口MessageType.java

/**

 */
package com.qq.common;

public interface MessageType {

	String message_succeed="1";//表明是登陆成功
	String message_login_fail="2";//表明登录失败
	String message_comm_mes="3";//普通信息包
	String message_get_onLineFriend="4";//要求在线好友的包
	String message_ret_onLineFriend="5";//返回在线好友的包
}

User.java

/**
