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
package com.scme.aserversocket; import java.io.BufferedReader; import java.io.BufferedWriter; import java.io.InputStreamReader; import java.io.OutputStreamWriter; import java.net.Socket; import android.app.Activity; import android.os.AsyncTask; import android.os.Bundle; import android.view.Menu; import android.view.MenuItem; import android.view.View; import android.view.View.OnClickListener; import android.widget.EditText; import android.widget.TextView; import android.widget.Toast; 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"); writer.flush(); 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。。。
