二、TCP客户端数据发送

public void Client_SendMessage(){try {Socket client = new Socket("192.168.124.6",8089);OutputStream out = client.getOutputStream();out.write("meng".getBytes());} catch (IOException e) {throw new RuntimeException(e);}}public void btn_client_send_clicked(View v){new Thread(new Runnable() {@Overridepublic void run() {Client_SendMessage();}}).start();}

三、TCP客户端数据接收

textView1 = findViewById(R.id.text_view);
textView1.setText("数据接收框");
textView2 = findViewById(R.id.text_view2);
textView2.setText("0");

new Thread(new Runnable() {@Overridepublic void run() {while (true){try {Socket client = new Socket("192.168.124.6",8089);int len;InputStream in = client.getInputStream();byte[] data = new byte[128];len = in.read(data);String str = new String(data,0,len);Message msg2 = new Message();Bundle b = new Bundle();b.putString("msg", str);msg2.setData(b);h2.sendMessage(msg2);} catch (IOException e) {throw new RuntimeException(e);}}}}).start();

h2 = new Handler(){@Overridepublic void handleMessage(Message msg2) {// TODO Auto-generated method stubsuper.handleMessage(msg2);Bundle b = msg2.getData();String string  = b.getString("msg");textView1.setText(string);}};
