Android基于socket的群聊程序

在网上看了好多，但是感觉不是太简单就是只能单独聊，所以就自己写了个可以群聊的，直接上代码了

一、服务器端

这里用的MyEclipse作为服务器端

MyServerScoket.java

package com.scme.server;

public class MyServerScoket {

    public static void main(String[] args) {
        new ServerListener().start();
    }
}

ServerListener.java

package com.scme.server;

import java.io.IOException;
import java.net.ServerSocket;
import java.net.Socket;

import javax.swing.JOptionPane;

public class ServerListener extends Thread {

    @Override
    public void run() {
        // 1-65535
        try {
            // 端口
            ServerSocket serverScoket = new ServerSocket(12345);
            while (true) {
                // 阻塞当前线程
                Socket socket = serverScoket.accept();
                // 建立连接，控制台打印
                System.out.println("有客户端连接到了本机的12345端口");
                // 弹出窗口提示
                JOptionPane.showMessageDialog(null, "有客户端连接到了本机的12345端口");
                //将socket传递新的线程
                ChatSocket cs = new ChatSocket(socket);
                cs.start();
                ChatManger.getChatManger().add(cs);
            }

        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

ChatSocket.java

package com.scme.server;

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.net.Socket;

public class ChatSocket extends Thread {

    Socket socket;

    public ChatSocket(Socket s){
        this.socket = s;
    }

    public void out(String out){
        try {
            socket.getOutputStream().write((out+"\n").getBytes("UTF-8"));
        } catch (Exception e) {
            e.printStackTrace();
        }

    }

    @Override
    public void run() {
        out("你已经连接到本服务器了");
        try {
            BufferedReader br = new BufferedReader(new InputStreamReader(socket.getInputStream(),"UTF-8"));
            String line = null;
            while ((line = br.readLine()) != null) {
                ChatManger.getChatManger().publish(this, line);
            }
            br.close();
        } catch (IOException e) {
            e.printStackTrace();
        }

    }
}

ChatManger.java

package com.scme.server;

import java.util.Vector;

public class ChatManger {

    //单例化
    private ChatManger(){}
    private static final ChatManger cm = new ChatManger();
    public static ChatManger getChatManger(){
        return cm;
    }

    Vector<ChatSocket> vector = new Vector<ChatSocket>();

    public void add(ChatSocket cs){
        vector.add(cs);
    }

    public void publish(ChatSocket cs,String out){
        for (int i = 0; i < vector.size(); i++) {
            ChatSocket csChatSocket = vector.get(i);
            if (!cs.equals(csChatSocket)) {
                csChatSocket.out(out);
            }
        }
    }
}

二、客户端

布局文件

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/container"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal" >

        <EditText
            android:id="@+id/ip"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_weight="0.6"
            android:hint="输入服务器的IP地址"
            android:text="10.0.2.2" >

        </EditText>

        <Button
            android:id="@+id/connect"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_weight="0.4"
            android:text="连接" />

    </LinearLayout>

    <ScrollView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_weight="0.86" >

        <TextView
            android:id="@+id/text"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:text="Ready..." />
    </ScrollView>

    <EditText
        android:id="@+id/edit"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:hint="在这里输入内容" />

    <Button
        android:id="@+id/send"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="发送" />

</LinearLayout>

Main.java

public class MainActivity extends Activity implements OnClickListener {

    private EditText ip,edit;
    private TextView text;

    private void init() {
        ip = (EditText) findViewById(R.id.ip);
        edit = (EditText) findViewById(R.id.edit);
        text = (TextView) findViewById(R.id.text);
        findViewById(R.id.connect).setOnClickListener(this);
        findViewById(R.id.send).setOnClickListener(this);
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        init();
    }

    Socket socket = null;
    BufferedWriter writer = null;
    BufferedReader reader = null;

    /**
     * 连接
     */
    public void connect(){
            AsyncTask<Void, String, Void> read = new AsyncTask<Void, String, Void>(){

                @Override
                protected Void doInBackground(Void... params) {
                    try {
                        socket = new Socket(ip.getText().toString(), 12345);
                        writer = new BufferedWriter(new OutputStreamWriter(socket.getOutputStream()));
                        reader = new BufferedReader(new InputStreamReader(socket.getInputStream()));
                        publishProgress("@success");
                    } catch (Exception e) {
                        Toast.makeText(MainActivity.this, "无法建立连接", 1000).show();
                        e.printStackTrace();
                    }
                    try {
                        String line;
                        while ((line = reader.readLine())!=null) {
                            publishProgress(line);
                        }
                    } catch (Exception e) {
                        e.printStackTrace();
                    }
                    return null;
                }

                @Override
                protected void onProgressUpdate(String... values) {
                    if (values[0].equals("@success")) {
                        Toast.makeText(MainActivity.this, "建立连接成功", 1000).show();
                    }
                    text.append("对方说："+values[0]+"\n");
                    super.onProgressUpdate(values);
                }

            };
            read.execute();
    }

    /**
     * 发送
     */
    public void send(){
        try {
            text.append("我说："+edit.getText().toString()+"\n");
            writer.write(edit.getText().toString()+"\n");

            edit.setText("");
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    @Override
    public void onClick(View v) {
        switch (v.getId()) {
        //连接
        case R.id.connect:
            connect();
            break;
        //发送
        case R.id.send:
            send();
            break;
        }
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();
        if (id == R.id.action_settings) {
            return true;
        }
        return super.onOptionsItemSelected(item);
    }
}

客户端任意开。。。

还有最重要的，别忘了在主配置文件里加入网络权限啊。。。
