Scheduler.scheduleFixedPeriod介绍

[英]Schedules a repeating command that is scheduled with a constant periodicity. That is, the command will be invoked every delayMs milliseconds, regardless of how long the previous invocation took to complete.
[中]计划以恒定周期计划的重复命令。也就是说，无论上一次调用需要多长时间才能完成，该命令都将每delayMs毫秒调用一次。
