简介：

9 | 本项目是一个简单的局域网多人聊天室安卓软件。实现局域网内的聊天室创建、搜索和加入。
10 |
11 |

功能：

12 | 必须在局域网的条件下使用(暂不完全支持热点，打开热点的用户将无法使用)。
13 | 使用时要在设置中打开软件的通知权限，本软件的提示是用Toast实现，不打开将无法看到提示。
14 | 取完昵称后可选择创建聊天室或加入局域网中他人的聊天室。
15 | 创建聊天室：创建服务器并加入到自己的聊天室中，同时向局域网可见。
16 | 加入聊天室：进入搜索界面，可搜索局域网的所有开启的聊天室，点击即可进入开始聊天。
17 | 对于客户端的加入与退出，聊天室内都有提示 “ 某某某 加入(离开)了聊天室 ”。
18 | 心跳检测：客户端连接服务器后会定时向服务器发送心跳包，服务器收到后向客户端返回心跳包。
19 |          如果当客户端因网络问题而连接不上的话，就可以检测已到离开聊天室。
20 |          服务器掉线的话就会结束聊天室。
21 | 处理了大部分异常，暂未发现大bug。
22 |
23 |

运用到的知识点：

24 | 封装、低耦合高内聚思想
25 | 安卓基础知识(Activity,Service,各种界面布局和View，自定义View)
26 | Socket(Socket、ServerSocket、MulticastSocket、DatagramSocket等)
27 | 多线程
28 | 异常处理
29 | 心跳检测机制
30 | IO流
31 | 集合
32 | Handler
33 | Dialog和Toast
34 | 安卓本地存储(SharedPreferences)
35 | 获取WIFI状态
36 |
37 |

项目结构：

38 | PrepareActivity ：准备界面，
39 | RoomsActivity ：搜索局域网内的聊天室界面
40 | ChatActivity  ：聊天主界面
41 | SquareImageView ：自定义正方形ImageView
42 | ServerService ：服务器类
43 | ServerThread  ：服务器聊天线程
44 | ServerThread.ClientChannel ：客户端在服务器的映射线程
45 | ServerResponseThread  ：服务器响应搜索请求线程
46 | SearchServerThread  ：客户端搜索服务器线程
47 | Client  ：客户端类
48 | Client.Connect  ：客户端连接线程
49 | Client.SendMsg  ：客户端发送消息线程
50 | Client.ReceviceMsg ：客户端接收消息线程
51 | Port  ：端口号类
52 | CostomUtil  ：自定义工具类
53 |
