SingleThreadPool构造方法

public static ExecutorService newSingleThreadExecutor() {    return new FinalizableDelegatedExecutorService(                new ThreadPoolExecutor(1,                 1,                 0L,                 TimeUnit.MILLISECONDS,                 new LinkedBlockingQueue
    
     ()));}复制代码
    

特点: 单个后台线程（其缓冲队列无界）。单线程串行执行所有任务。

使用案例：

val pool: ExecutorService = Executors.newSingleThreadExecutor()复制代码

txt.click {    for (i in 0 until 30) {        val runnable = Runnable {            try {                Thread.sleep(2000)                log("当前线程是：", Thread.currentThread.name)            }catch(e: Exception) {                e.printStackTrace()            }        }        pool.execute(runnable)    }}复制代码
