AsyncTask的和线程之间真正的区别 [英] Real difference between AsyncTask and Thread

问题描述

我一直在阅读Android文档（ AsyncTask的，的发）和的 vogella教程这件事情，但我怀疑呢。

I have been reading Android documentation (AsyncTask, Thread) and vogella tutorial about this matter, but I have doubts yet.

例如，我想发送一条消息，因为Android应用到服务器。我想处理它的响应。我应该怎么使用？

For example, I wish send a message since an Android app to a server. And I would like process its response. What should I use?

我看到他们创建新线程为不会阻止用户界面的例子，但这样一来，我们没有过程的进展，还必须处理线程内的响应，因为run（）方法不返回任何

I have seen examples where they create a new Thread for not block UI, but this way we have not the progress of process, also you have to process the response within the thread because the run() method don't returning anything.

AsyncTask的似乎比线程更好的选择，但我不知道是否有关于Android如何运行的AsyncTask或线程一些consecuences。

AsyncTask seems better option than Thread, but I don't know if there are some consecuences about how Android run an AsyncTask or a Thread.
