一:无大小限制的线程池执行效果如下
1.gif
二:限制按顺序来执行任务的线程池效果如下
2.gif
三:一个一个任务的执行线程池效果如下(与按顺序执行效果是一样的,只是内部实现稍有不同)
3.gif
四:按指定个数来执行任务的线程池效果如下
4.gif
五:创建一个可在指定时间里执行任务的线程池,亦可重复执行,不常用,效果与四相同
5.gif
六:按指定工厂模式来执行的线程池,效果与四、五一样,但用方式六创建的线程池都有在工厂中指定的线程属性,
比如:线程名字、是否为用户线程等等属性
6.gif
七:线程池中任务执行时可暂停效果图如下
7.gif
八:用Runnable、ConcurrentLinkedQueue、ConcurrentMap、Future、ExecutorService关联实现的效果图如下
8.gif
哦的了,效果看完了,现在就请大家自行修改AndroidManifest.xml中主Activity的入口来看两种不同方式实现的代码效果吧,首先,先贴一下Main.java类的代码,希望大家详细看里面的注释,一定要详细看,你不会吃亏的,相信我!
方式一(纯ExecutorService、AsyncTask、Runnable关联实现相关文件如下):
