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

  super.oncreate(savedinstancestate);
  setcontentview(r.layout.activity_main);

  // 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() {

    // 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();
   // }
  }
 }

   ((thread) receive).interrupt();
  }
 }
}
