http://www.cnblogs.com/yangfengwu/p/8776712.html 先把源码和资料链接放到这里 链接：https://pan.baidu.com/s/10MxI8-Q33-M_R2WEHqEi1A密码：j1sz 先做手机的,然后做C#的 详细点的可以看我这篇文章,请参考着这篇看这篇文章,这篇文章会解决一些细节问题 http://www.cnblogs.com/yangfengwu/p/5212570.html 咱们不做很复杂的直接越简单越好,就做成这样 先编译一下 不用管,后期的话咱会用一下 最后做成这样子 发现还是有点大.. 把像素低的放到像素高的里面图片显示出来会缩小,把像素高的放到像素低的里面图片显示出来会放大 protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); imageViewLamp = (ImageView) findViewById(R.id.imageView1); switchLamp = (Switch) findViewById(R.id.switch1); switchLamp.setOnCheckedChangeListener(switchLamplistener);//设置SWITCH的状态改变事件 } private OnCheckedChangeListener switchLamplistener = new OnCheckedChangeListener() { @Override public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { // TODO Auto-generated method stub // Toast.makeText(getApplicationContext(), isChecked+"", 500).show(); if (isChecked) {//切换图片 imageViewLamp.setImageResource(R.drawable.ledon); } else { imageViewLamp.setImageResource(R.drawable.ledoff); } } }; 现在做点击连接按钮就连接服务器 刚看到............... 有点迫不及待的想试一试腾讯云了, 下面做的是:点击连接按钮,连接TCP服务器,连接上以后启动数据接收任务,因为数据接收任务可以判断是不是和服务器断开了连接 然后按钮显示"断开",如果意外断开了连接也显示断开.... public class MainActivity extends Activity { ImageView imageViewLamp;//灯的图片 Switch switchLamp;//灯的控制开关 EditText editTextIPAdress,editTextPort;//ip地址和端口号的编辑框 Button buttonConnect;//连接按钮 Socket socket;//cocket boolean ConnectFlage = false;//连接标志,控制按钮显示连接和断开 ThreadConnectService threadConnectService = new ThreadConnectService();//建立一个连接任务的变量 InputStream inputStream;//获取输入流,可以用来判断有没有断开连接 ThreadReadData threadReadData = new ThreadReadData();//接收数据的任务的变量 boolean threadReadDataFlage = false;//接收数据任务一直运行控制 byte[] ReadBuffer = new byte[1024];//存储接收到的数据 int ReadBufferLengh = 0;//接收到的数据个数 @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState);
