Android开发中，线程池工具类的封装与使用。
一、线程池工具类
/**
* 线程池工具类
* @author zhangjikai

*/
public class ThreadPoolUtil {
//核心线程数为5
private static int CORE_POOL_SIZE=5;
//线程池最大线程数
private static int MAX_POOL_SIZE=20;
//额外线程空状态生存时间
private static int KEEP_ALIVE_TIME=10000;
//阻塞队列。当核心线程都被占用，且阻塞队列已满的情况下，才会开启额外线程。
private static BlockingQueueblockingQueue=new ArrayBlockingQueue(10);
//线程池
private static ThreadPoolExecutorthreadPool;
//无参构造方法
public ThreadPoolUtil() {
}
//线程工厂
private static ThreadFactorythreadFactory=new ThreadFactory() {
private final AtomicIntegerinteger=new AtomicInteger();
@Override
public Thread newThread(Runnable runnable) {
return new Thread(runnable,"myThreadPool thread:" +integer.getAndIncrement());
}
};
//静态代码块
static {
threadPool=new ThreadPoolExecutor(CORE_POOL_SIZE,MAX_POOL_SIZE,KEEP_ALIVE_TIME,TimeUnit.SECONDS,blockingQueue,threadFactory);
}
public static void execute(Runnable runnable) {
threadPool.execute(runnable);
}
public static void execute(FutureTask futureTask) {
threadPool.execute(futureTask);
}
public static void cancel(FutureTask futureTask) {
futureTask.cancel(true);
}
}
二、使用
private void testPool(){
ThreadPoolUtil.execute(new Runnable() {
@Override
public void run() {
/**
* 这里写你需要执行的操作
*/
}
});
}
