一，简介
创建Socket，连接服务器地址和端口号，进行发送信息。

二，实现
启动线程发送信息

  data = et.getText().toString();if(data == null){Toast.makeText(MainActivity.this,"please input Sending Data", Toast.LENGTH_SHORT).show();}else {//在后面加上 '\0' ,是为了在服务端方便我们去解析；data = data + '\0';}Thread thread = new Thread(){@Overridepublic void run() {super.run();try {sockets = new Socket(ip,8000);outputStream = sockets.getOutputStream();outputStream.write(data.getBytes());} catch (IOException e) {e.printStackTrace();}}};thread.start();
