平常開發(fā)中網(wǎng)絡(luò)請(qǐng)求自從Android4.0后強(qiáng)制要求放到子線程中避免主線程進(jìn)行網(wǎng)絡(luò)請(qǐng)求，一般很多人習(xí)慣直接通過new Thread的方法。不建議這樣使用。我們用ThreadPoolExecutor線程池這個(gè)類創(chuàng)建比較好。所以有了下面的線程池工具類。

先來張JDK1.6的中文參數(shù)說明

package com.xiayiye.honorfirst.utils;import java.util.concurrent.BlockingQueue; import java.util.concurrent.Executors; import java.util.concurrent.LinkedBlockingQueue; import java.util.concurrent.RejectedExecutionHandler; import java.util.concurrent.ThreadFactory; import java.util.concurrent.ThreadPoolExecutor; import java.util.concurrent.TimeUnit;/*** @author xiayiye* 線程池工具*/ public class ThreadUtils {/*** 根據(jù)cup核心數(shù)設(shè)置線程池?cái)?shù)量*/private static int corePoolSize = Runtime.getRuntime().availableProcessors();/*** 最大線程池?cái)?shù)量= cpu核心數(shù)*2+1*/private static int maximumPoolSize = corePoolSize * 2 + 1;/*** 等待線程的存活時(shí)間*/private static long keepAliveTime = 1;/*** 等待線程存活時(shí)間的單位*/private static TimeUnit unit = TimeUnit.HOURS;/****/private static BlockingQueue<Runnable> workQueue = new LinkedBlockingQueue<>();/*** 默認(rèn)的線程工廠*/private static ThreadFactory threadFactory = Executors.defaultThreadFactory();/*** 取消策略，當(dāng)超過等待線程池的數(shù)量后禁止添加了*/private static RejectedExecutionHandler handler = new ThreadPoolExecutor.AbortPolicy();private static ThreadPoolExecutor executor;/*** 開啟線程池** @param runnable runnable*/public static void startThread(Runnable runnable) {executor = new ThreadPoolExecutor(corePoolSize,maximumPoolSize,keepAliveTime, unit,workQueue,threadFactory,handler);executor.execute(runnable);}/*** 取消線程池** @param runnable runnable*/public static void cancelThread(Runnable runnable) {if (null == runnable || executor == null) {return;}executor.remove(runnable);} }

?

調(diào)用就更簡單了。

ThreadUtils.startThread(runnable); ThreadUtils.cancelThread(runnable);

一個(gè)是開啟線程池，一個(gè)是取消線程池

總結(jié)
