服务器端的工作非常简单，建立socket.监听，代码如下：
package com.hdc.socket;
import java.io.IOException;
import java.io.OutputStream;
import java.net.ServerSocket;
import java.net.Socket;
public class JavaServer {
public static void main(String[] args) {
try {
ServerSocket server = new ServerSocket(8888);
while (true) {
System.out.println("execute 1\n");
Socket client = server.accept();
System.out.println("execute 2\n");
OutputStream out = client.getOutputStream();
System.out.println("execute 3\n");
String msg = "hello android";
out.write(msg.getBytes());
System.out.println("execute 4\n");
client.close();
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
端口号：8888，等待客户端连接！
然后看android客户端的编码：
因为操作线程不能在主线程，故：
1 package com.hdc.sockettestclient; 2 3 import android.app.Activity; 4 import android.os.Bundle; 5 import android.widget.TextView; 6 7 public class MainActivity extends Activity { 8 private TextView myTextView; 9 10 @Override 11 protected void onCreate(Bundle savedInstanceState) { 12 super.onCreate(savedInstanceState); 13 setContentView(R.layout.activity_main); 14 15 myTextView = (TextView) findViewById(R.id.textView1); 16 17 new YunTheard(myTextView).start(); 18 19 } 20 }
package com.hdc.sockettestclient;
import java.io.IOException;
import java.io.InputStream;
import java.net.Socket;
import java.net.UnknownHostException;
import android.widget.TextView;
public class YunTheard extends Thread {
private TextView myTextView;
public YunTheard(TextView myTextView) {
super();
this.myTextView = myTextView;
}
@Override
public void run() {
try {
myTextView.setText("0");
Socket socket = new Socket("172.17.1.41", 8888);
myTextView.setText("1");
InputStream in = socket.getInputStream();
byte[] buffer = new byte[in.available()];
myTextView.setText("2");
in.read(buffer);
myTextView.setText("3");
String msg = new String(buffer);
myTextView.setText(msg);
} catch (UnknownHostException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
}
通信成功后客户端会显示来自服务端的hello，android
