6-51单片机ESP8266学习-AT指令(8266TCP服务器--做自己的AndroidTCP客户端发信息给单片机控制小灯的亮灭)

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/1jpHZjW_7pQKNfN9G4B6ZjA     密码：nhn3 

先做手机的,然后做C#的

详细点的可以看我这篇文章,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

 

 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);
        setContentView(R.layout.activity_main);
        
        editTextIPAdress = (EditText) findViewById(R.id.editText1);
        editTextPort = (EditText) findViewById(R.id.editText2);
        buttonConnect = (Button) findViewById(R.id.button1);
        buttonConnect.setOnClickListener(buttonConnectClick);
        
        imageViewLamp = (ImageView) findViewById(R.id.imageView1);
        switchLamp = (Switch) findViewById(R.id.switch1);
        switchLamp.setOnCheckedChangeListener(switchLamplistener);
    }

                imageViewLamp.setImageResource(R.drawable.ledon);
            }
            else {
                imageViewLamp.setImageResource(R.drawable.ledoff);
            }
        }
    };

 忘了说一件事情....加权限

我把上面做的打包了
