开个玩笑，但我能通过查看文档来了解这一点。重要的部分隐藏在评论中

WorkManager.getInstance(myContext)
    .beginWith(workA)
        // Note: WorkManager.beginWith() returns a
        // WorkContinuation object; the following calls are
        // to WorkContinuation methods
    .then(workB)    // FYI, then() returns a new WorkContinuation instance
    .then(workC)
    .enqueue()

但这只是你想要的答案的一部分，你会想做这样的事情。

val workTaskList: List<WorkRequest> // Some list of tasks
var workContinuation = WorkManager.getInstance(myContext)
    .beginWith(workTaskList[0]) // Ensure 0 is indexable... 
     for(i 1..workTaskList.size) {
       //Make sure you update workContinuation or all the thens won't get enqueued
        workContinuation = workContinuation.then(workTaskList[i])
     }
workContinuation.enqueue()

我也有同样的问题，也许你可以让你的列表任务是静态的，并开始下一个任务时，成功的最后一个。

这是我用Java实现的代码，任何需要它的人都可以使用
1.将您的WorkRequests添加到List（我使用的是ArrayList）
1.然后构建第一个WorkRequest，它将返回WorkContinuation对象
1.使用该对象对更多的WorkRequest进行排队，每个WorkRequest将返回一个新的WorkContinuation对象。每次排队将返回一个新的WorkContinuation对象，并将下一个对象添加到该对象中
1.终于enqueue()他们。

//Add WorkRequest to ArrayList for chaining them
 ArrayList<OneTimeWorkRequest> workRequests = new ArrayList<>();
 int userCount = prefs.getInt("login_accounts", 0);

 //Build and Add all WorkRequests to the ArrayList
 for (int i = 0; i < userCount; i++) {
     Data inputData = new Data.Builder()
                 .putInt("user_id", i)
                 .build();
     OneTimeWorkRequest completeDailySearchesForUser =
                 new OneTimeWorkRequest.Builder(DailySearches.class)
                         .setConstraints(constraints)
                         .setInputData(inputData)
                         .build();
     workRequests.add(completeDailySearchesForUser);
 }

 // check if you have more than 1 WorkRequest in ArrayList
 if (workRequests.size() > 1) {
     // Add the first one and remove it from ArrayList
     WorkContinuation workContinuation = WorkManager.getInstance(context.getApplicationContext())
                 .beginWith(workRequests.remove(0));

     // Loop over the remaining requests and chain them
     for (OneTimeWorkRequest userWorkRequest : workRequests ) {
             workContinuation = workContinuation.then(userWorkRequest);
     }
     // Finally call enqueue to kick things off
     workContinuation.enqueue();
 } else {
     // If there is only 1 request in list, add a normal request
     // This will ignore calling WorkManager if the list is empty (workRequests.size() = 0)
     if (workRequests.size() == 1) WorkManager.getInstance(context.getApplicationContext())
                 .enqueue(workRequests.get(0));
 }
