主类：MainActivity.java代码如下

public class MainActivity extends Activity {

private TextView testview=null;

private Button button=null;

private EditText text=null;

protected Handler handler=null;

private OutputStream out=null;

private Socket s = null;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

this.testview=(TextView)super.findViewById(R.id.test);

this.button=(Button)super.findViewById(R.id.button);

this.text=(EditText)super.findViewById(R.id.edit);

this.handler=new Handler(){

@Override

public void handleMessage(Message msg) {

super.handleMessage(msg);

if (msg.what==0x123) {

testview.append("客户端说："+msg.obj.toString()+"\n");

}

}

};

//4.0之后访问网络不能在主程序中进行，要将代码放在线程中，不然会报错。

new Thread(new Runnable() {

@Override

public void run() {

try {

s=new Socket("10.0.2.2", 30000);

new Thread(new ClientThread(s, handler)).start();

out=s.getOutputStream();

} catch (IOException e) {

e.printStackTrace();

}

}

}).start();

this.button.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

try {

out.write((text.getText().toString()+"\n").getBytes("utf-8"));

text.setText("");

}catch (IOException e) {

e.printStackTrace();

}

}

});

}

@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;

}

}

线程类：ClientThread.java代码如下

public class ClientThread implements Runnable {

private Socket socket=null;

private Handler handler=null;

BufferedReader br=null;

public ClientThread(Socket s,Handler handler) throws IOException {

this.socket=s;

this.handler=handler;

br=new BufferedReader(new InputStreamReader(s.getInputStream()));

}

@Override

public void run() {

try {

String connet=null;

while ((connet=br.readLine())!=null) {

Message message=new Message();

message.what=0x123;

message.obj=connet;

handler.sendMessage(message);

}

} catch (IOException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

}

}

服务端代码：

线程服务类：ServerTherad.java代码如下

public class ServerTherad implements Runnable {

private Socket s = null;

private BufferedReader buRead = null;

StringBuffer stb=new StringBuffer();

public ServerTherad(Socket s) throws IOException {

this.s = s;

this.buRead = new BufferedReader(new InputStreamReader(

this.s.getInputStream(), "utf-8"));

}

@Override

public void run() {

String connet=null;

try {

while ((connet=readFromClient())!=null) {

//System.out.println("信息\n"+stb.append(connet));

System.out.println("客户端说："+connet);

for (Socket ss:SimpleServer.socketList) {

OutputStream out=ss.getOutputStream();

out.write((connet+"\n").getBytes("utf-8"));

}

}

} catch (IOException e) {

e.printStackTrace();

}

}

private String readFromClient(){

try {

return buRead.readLine();

} catch (Exception e) {

//删除此Socket

SimpleServer.socketList.remove(s);

}

return null;

}

}

服务例子测试：SimpleServer.java代码如下

public class SimpleServer {

public static ArrayList socketList=new ArrayList();

public static void main(String[] args) throws IOException {

Scanner sc = new Scanner(System.in);

ServerSocket ss=new ServerSocket(30000);

while (true) {

Socket s=ss.accept();

socketList.add(s);

new Thread(new ServerTherad(s)).start();

}

}

}

注意：测试要先启动服务端运行，然后再启动客户端运行
