Android连接服务器端的Socket的实例代码

废话不多说了，直接给大家贴代码了，具体代码如下所述：

package com.exa

mple.esp8266;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.io.PrintStream;
import java.net.Socket;

private EditText edSend, edReceive;
private Button btnConnect, btnSend;
private Handler myHandler;
private SendThread SendThread;
private boolean isReceive = false;
private boolean isConnect = false;
private static final String HOST = "192.168.4.1";
private static final int PORT = 333;
String strMessage;
Socket socket = null;
@Override
protected void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 setContentView(R.layout.activity_main);
 edSend = (EditText) findViewById(R.id.edSend);
 edReceive = (EditText) findViewById(R.id.edReceive);
 btnConnect = (Button) findViewById(R.id.btConnect);
 btnSend = (Button) findViewById(R.id.btSend);
 // 连接
 btnConnect.setOnClickListener(new View.OnClickListener() {
  public void onClick(View v) {
   // TODO Auto-generated method stub
   if (!isConnect) {
    new Thread(connectThread).start();
    isConnect = true;
   }
  }
 });
 // 发送
 btnSend.setOnClickListener(new View.OnClickListener() {
  public void onClick(View v) {
   // 启动发送线程
   new Thread(SendThread).start();
  }
 });
 myHandler = new Handler() {// UI主线程消息处理函数
  public void handleMessage(Message msg) {
   Bundle bundle = msg.getData();
   String string = bundle.toString();
   edReceive.setText(string);
  }
 };
}
// 连接到服务器的接口
Runnable connectThread = new Runnable() {
 public void run() {
  // TODO Auto-generated method stub
  try {
   socket = new Socket(HOST, PORT);
   if (socket != null)
    Toast.makeText(getApplicationContext(), "连接成功",
      Toast.LENGTH_LONG).show();
   else
    Toast.makeText(getApplicationContext(), "连接失败",
      Toast.LENGTH_LONG).show();
   // 初始化发送线程
   SendThread = new SendThread(socket);
  } catch (IOException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  }
 }
};
// 接收消息的接口
Runnable Receive = new Runnable() {
 InputStream inStream;
 private byte[] buffer;
 private String str = null;
 public void run() {
  // TODO Auto-generated method stub
  while (!isReceive) {
   buffer = new byte[512];
   try {
    inStream = socket.getInputStream();
    inStream.read(buffer);
   } catch (IOException e) {
    e.printStackTrace();
   }
   str = new String(buffer);
   Bundle bundle = new Bundle();
   bundle.get(str);
   Message message = new Message();
   message.setData(bundle);
   myHandler.sendMessage(message);
  }
 }
};
// 发送线程
private class SendThread extends Thread {
 private OutputStream outStream = null;
 private String str = null;
 SendThread(Socket socket) {
  try {
   outStream = socket.getOutputStream();
  } catch (IOException e) {
   e.printStackTrace();
  }
 }
 public void run() {
  // while(true){
  str = edSend.getText().toString().trim();
  PrintStream pt = new PrintStream(outStream);
  pt.print(str);
  new Thread(Receive).start();
  // }
 }
}
protected void onDestroy() {
 // TODO Auto-generated method stub
 super.onDestroy();
 if (Receive != null) {
  isReceive = false;
  ((Thread) Receive).interrupt();
 }
}
}
