Android jetpack里 WorkManager如何定义内部类的Work类，而不是单独写一个类？

您可以通过以下方式定义内部类作为Work类：

1. 在WorkManager.enqueue()方法中直接使用匿名内部类作为Work类的实现，例如：

workManager.enqueue(new WorkRequest.Builder()
        .setInputData(data)
        .build()
        .createWorker(getApplicationContext(), new CoroutineWorker() {
                    @NonNull
                    @Override
                    public Result doWork() {
                        // Your work logic here
                        return Result.success();
                    }
                }));

2. 通过在Worker类中定义一个静态方法来创建内部类实例，例如：

public class MyWorker extends Worker {
    public MyWorker(@NonNull Context context, @NonNull WorkerParameters workerParams) {
        super(context, workerParams);
    }

    // Static factory method for constructing the inner class instance
    private static MyInnerWorker createInnerWorker() {
        return new MyInnerWorker();
    }

    @NonNull
    @Override
    public Result doWork() {
        // Delegate work to the inner class
        MyInnerWorker innerWorker = createInnerWorker();
        return innerWorker.doWork();
    }

    // Inner Work class
    private static class MyInnerWorker extends Worker {
        @NonNull
        @Override
        public Result doWork() {
            // Your work logic here
            return Result.success();
        }
    }
}

然后您可以使用MyWorker.enqueue()方法来添加工作请求。
