AsyncTask 和 Thread 的真正区别 [英] Real difference between AsyncTask and Thread

问题描述

我一直在阅读 Android 文档(AsyncTask、线程) 和 vogella 教程关于这个问题，但我还有疑问.

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

例如，我想从 Android 应用程序向服务器发送消息.我希望这个过程能够响应.我应该用什么?

For example, I want to send a message from an Android app to a server. And I would like this process to be responsive. What should I use?

我见过他们为非阻塞 UI 创建一个新的 Thread 的例子，但是这样我们就没有进程的进度，你也必须在 中处理响应Thread 因为 run() 方法不返回任何东西.

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

AsyncTask 似乎比 Thread 更好，但我不知道使用 AsyncTask 而不是 的后果是什么>线程.

AsyncTask seems better option than Thread, but I don't know what are the consequences of using an AsyncTask instead of a Thread.
