本文介绍了WorkManager和RxJava2的互操作性。在gradle文件中添加依赖，继承特定类，重写方法返回执行状态。默认返回值在后台线程订阅，可重写方法更改订阅线程。停止操作会正确处理，无需特殊处理工作停止情况。

We provide interoperability between WorkManager and RxJava2. To get started, include work-rxjava2 dependency in addition to work-runtime in your gradle file. Then, instead of extending Worker, you should extend RxWorker. Finally override the RxWorker.createWork() method to return a Single<Result> indicating the Result of your execution, as follows:

public class RxDownloadWorker extends RxWorker {

    public RxDownloadWorker(Context context, WorkerParameters params) {
        super(context, params);
    }

    @Override
    public Single<Result> createWork() {
        return Observable.range(0, 100)
            .flatMap { download("https://www.google.com") }
            .toList()
            .map { Result.success() };
    }
}

Note that RxWorker.createWork() is called on the main thread, but the return value is subscribed on a background thread by default. You can override RxWorker.getBackgroundScheduler() to change the subscribing thread.

Stopping an RxWorker will dispose the Observers properly, so you don't need to handle work stoppages in any special way.
