android - 循环完成迭代时的 RxJava 调用方法

Question

我有问题。解决方案很简单，但我的头太热了......

我想在 forEach 循环完成工作后调用一次方法。

感谢您提供任何示例解决方案！

 override fun saveWorkers(workers: ArrayList<Worker>): Single<Boolean> {
    LogMgr.d(TAG, "saveWorkers() : $workers")

    // remove old workers for current Event Planner and save new
    workers.forEach {
        deleteOldWorkers(it.event_planner_id!!)
                .subscribeOn(getSubscriptionSchedulerForSave())
                .subscribe({ status ->

                }, { error ->

                })
    }

    return Single.create({ emitter ->
        RXModelAdapter.from(Worker::class.java)
                .saveAll(workers)
                .subscribeOn(getSubscriptionSchedulerForSave())
                .subscribe({
                    LogMgr.d(TAG, "saveWorkers() onComplete")
                    emitter.onSuccess(true)

                }, {
                    LogMgr.e(TAG, "saveWorkers() onError ", it)
                    emitter.onError(it)
                })
    })
}

1. 建议的解决方案

       Observable.merge(workers.map {
       deleteOldWorkers(it.event_planner_id!!)
   })

Observable.merge(workers.map { deleteOldWorkers(it.event_planner_id!!) }).doOnComplete()也许？
