Android 中AsyncTask后台线程，异步任务的理解

前言：简单介绍：AsyncTask是标准Java线程的一个包装类，它封装了最常见的模式：在子线程中执行后台工作，然后与UI线程同步以发送进度和最终结果。AsyncTask允许以串行或并行的方式或者通过自己的线程池执行后台的任务。AsyncTask类实现了将耗时的操作移到了后台线程中，然后与UI线程同...

Android开发实践：线程与异步任务

基于移动客户端的软件特别强调实时性，Android程序更是如此，任何一个程序超过5s没有响应，都会被系统强制杀掉。而且Android也不允许在UI线程中进行任何网络操作，否则就会产生NetworkOnMainThreadException 异常。因此，凡是耗时的操作，都不应该直接出现在UI线程中。今...

Android异步任务详解 AsynTask

android提供了一套专门用于异步处理的类。即：AynsTask类。使用这个类可以为耗时程序开辟一个新线程进行处理，处理完时返回。　　其实，AsynTask类就是对Thread类的一个封装，并且加入了一些新的方法。编程时，两者都可以实现同样的功能。本文后面将对AsynTask和Thread进行比...
