android studio开发：定时执行

5秒执行一次

public void timeoutReconnect() {        scheduler = Executors.newSingleThreadScheduledExecutor();        scheduler.scheduleAtFixedRate(new Runnable() {            @Override            public void run() {                try {                     //定时执行的语句                    }                } catch (Exception e) {                    // e.printStackTrace();                }            }        }, 0 * 500, 10 * 500, TimeUnit.MILLISECONDS);    }
