因为需要对请求到的数据进行处理后在渲染到视图上，所以借助 handleDate 变量来对原始的

数据 data2 进行处理，

如上当 thisdata2 = thishandleDate 时，最后渲染的数据发现 handleDate 的数据也被改变了。

解决方法：

因为

1、在vue中 thisA = thisB,没有进行深层赋值，只是把thisA的地址指向了与thisB相同的地址，所有对于A的修改会影响到B

2、解决相互影响的思路是在thisA必须是新建的一个对象，这样才能保证不被指向同一地址，属性修改不会相互影响。

thisA=JSONparse(JSONstringify(thisB));

将对象转成字符串剔除对象属性后,再转换成对象赋值，这样能解决指向相同地址修改会相互影响的问题。里面的thisA= JSONparse(JSONstringify(thisB)); 如果是直接thisA= thisB的话会把 thisA替换为thisB然后再把thisB赋值给thisA相当于 thisA= thisA所以先转json字符串 再转数组 然后赋值给thisA这样不会相互影响

呵呵,不知道是不是我想的太简单

通信结果可以用Message去封装,msg可以包含what arg1 arg2 obj最多四种参数,obj是你需要用的,把obj附带上你的数据,貌似obj需要实现序列化接口,

然后异步线程可以调用主线程的handler发送消息msg,给handlemessage处理

如果你说的异步线程是AsynTask 那他本身就实现了上面的机制,他内部有方法,调用publishProgress(value);会把values传给onProgressUpdate(String values)处理(假设你的数据是String就写String,AsynTask<>,尖括号里面相应参数也填String)

在重写onProgressUpdate里调用service的一个方法

调不了service对象就需要在构造方法里传进来一个service对象

如果只需要一个最终结果,就在onPostExecute(Result或你喜欢的类型)方法里调用service处理这个result,,并且需要在doinBackGround你return这个结果
