8-51单片机ESP8266学习-AT指令(8266TCP服务器
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
protectedvoid 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
}
privateOnCheckedChangeListener switchLamplistener =new OnCheckedChangeListener() {
@Override
publicvoid 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....

忘了说一件事情....加权限

我把上面做的打包了

发送数据是写在了一个任务里面
整体的源码
本来想这一节也写好C#的,不过感觉写的够多的了,所以C#的放到下一节
下一篇
