问题描述
对于 OneTimeWorkRequest ，我们可以使用 setInitialDelay 来指定初始延迟.
For OneTimeWorkRequest, we can have setInitialDelay to specific the initial delay.
但是，没有针对 PeriodicWorkRequest 的工具.
However, there isn't such facility for PeriodicWorkRequest.
有没有可靠的方法来实现这一目标?
一种不那么可靠的方法是让一个延迟的 OneTimeWorkRequest 工作者来设置 PeriodicWorkRequest .但是，这非常麻烦，并且可能导致 OneTimeWorkRequest 失败并且无法安装 PeriodicWorkRequest .
One of the less reliable way, is to have a delayed OneTimeWorkRequest worker, to setup PeriodicWorkRequest. However, that's quite cumbersome, and create a possibility, where OneTimeWorkRequest may fail and not able to install PeriodicWorkRequest.
推荐答案
由于 androidx.work:work-*:2.1.0 ， PeriodicWorkRequests 支持初始延迟.您可以在 PeriodicWorkRequest.Builder 上使用 setInitialDelay 方法来设置初始延迟.
Since androidx.work:work-*:2.1.0, PeriodicWorkRequests support initial delays. You can use the setInitialDelay method on PeriodicWorkRequest.Builder to set an initial delay.
