Socket实现简易聊天室
利用socket套接字实现简易聊天室，下面是简易的安卓客户端和电脑实现交互，
实现界面：
客户端：
服务器端：
代码如下
服务器端MySocketServer.Java：（服务器端新建一个javaProject）
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.net.ServerSocket;
import java.net.Socket;
public class MySocketServer {
public static void main(String[] args)throws IOException{
ServerSocket serversocket=new ServerSocket(30000);
System.out.println("=======连接成功========");
while(true){
final Socket socket=serversocket.accept();
Thread t=new Thread(new Runnable(){
public void run() {
// TODO Auto-generated method stub
try {
InputStream input=socket.getInputStream();
OutputStream output=socket.getOutputStream();
BufferedReader buff=new BufferedReader(new InputStreamReader(input));
output.write("服务器:小朋友，你好呀！".getBytes("UTF-8"));
output.flush();
socket.shutdownOutput();
String line="";
while((line=buff.readLine())!=null){
System.out.println(line);
}
output.close();
input.close();
buff.close();
socket.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
});
t.start();
}
}
}
客户端 ：（安卓project）
1.MainActivity代码

text3.append(""+bundle.getString("msg")+"\n");
}
}
};
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
edit1=(EditText)findViewById(R.id.edit1);
edit2=(EditText)findViewById(R.id.edit2);

button.setOnClickListener(new View.OnClickListener() {

// TODO Auto-generated method stub
name=edit1.getText().toString();

text3.append("我:"+message+"\n");
new Thread(new Mythread()).start();
}
});
}
class Mythread implements Runnable{
public void run(){
Message m=new Message();
m.what=0x101;
Bundle bundle=new Bundle();
Socket socket =new Socket();
try {
socket.connect(new InetSocketAddress("10.248.25.146", 30000), 10000);
OutputStream os=socket.getOutputStream();
os.write((name+":"+message).getBytes("UTF-8"));
BufferedReader buff=new BufferedReader(new InputStreamReader(socket.getInputStream()));
String line=null;
buffer="";
while((line=buff.readLine())!=null){
buffer=buffer+line;
}
os.flush();
bundle.putString("msg", buffer.toString());
m.setData(bundle);
handler.sendMessage(m);
buff.close();
os.close();
socket.close();
} catch(SocketTimeoutException e){
bundle.putString("msg","连接超时！" );
m.setData(bundle);
handler.sendMessage(m);
}catch (IOException ee) {
// TODO Auto-generated catch block
ee.printStackTrace();
}
}
}
}
2.xml代码
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="wrap_content"
android:layout_height="wrap_content"

android:text="send"/>
<TextView
android:id="@+id/text2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBaseline="@+id/edit2"
android:layout_alignBottom="@+id/edit2"
android:layout_alignParentLeft="true"
android:text="信息：" />
<TextView
android:id="@+id/text3"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="@+id/button"
android:scrollbars="vertical"/>
</RelativeLayout>
这样就能实现啦！
（ps1：只能在同一局域网内聊天，可以修改ip获取方式打破这一局限！）
（ps2：可以修改服务器端实现多人在线聊天！）
