Android网络请求代码封装
你还在烦恼网络请求给你带来的麻烦吗？你还在一个主线程开启一个Thread然后start吗？你还在通过handler+message或者是AsyncTask来执行异步请求搞得代码很乱自己都蒙圈了嘛？你还在用些网络求框架吗？（不错的框架推荐用），用这些框架你的代码有mvc，mvp吗？还是这样的话你就太依赖于别人了。我们还是自己写写吧！
基于web开发的思想的service层次，写了这样的代码，
通常Android开发有后台网站的支持，大家都知道，然而Android网络请求本来就是应用程序的核心基础，然而好多网络框架都没有直接获取返回结果的，一般都写要去实现回调接口，才能获取到返回数据，这样就给我们代码在抽取的时候带来很大的麻烦，要是有一个方法填入参数就能获取返回结果的，岂不是给程序开发带来很大的便利，让程序员把重点放在逻辑处理上，所以我就写了一个这样的代码，希望能帮到哪些热爱Android开发的小伙子们；
下面就来看看代码怎么实现的吧；
代码有点多哦

测试效果如下
在activity中
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
test.setText(de());
}
String de(){
String url="http://10.187.23.43:8080/lrdd/TUserAction!login.action?name=doublejiang&passowrd=123";
HttpRequsetToRespnose hrtr=new HttpRequsetToRespnose(2);
String h=hrtr.get(url);
return h;
}
好了，就是这个了，要大家觉得好的话记得定一个，或者有什么更好的建议大家一起商量。
