我试图运行一个长时间运行的任务,该任务可能会失败,我尝试重试列表中的某些对象,但它会重新订阅整个observable列表。我可以做嵌套订阅,但似乎错了。有没有比嵌套订阅更好的解决方案?
这是我的实施:
public Observable<ReportItemModel> deferReports() {
return Observable.defer(new Callable<ObservableSource<? extends ReportItemModel>>() {
@Override
public ObservableSource<? extends ReportItemModel> call() throws Exception {
return Observable.fromIterable(getReports())
.map(new Function<Report, ReportItemModel>() {
@Override
public ReportItemModel apply(Report report) throws Exception {
return report.getReport();
}
});
}
});
}
reportFactory.deferReports()
.observeOn(AndroidSchedulers.mainThread())
.subscribeOn(Schedulers.io())
.retry()
.subscribe(new Observer<ReportItemModel>() {
@Override
public void onSubscribe(Disposable d) {
}
@Override
public void onNext(ReportItemModel value) {
Log.d(TAG,value.toString());
}
@Override
public void onError(Throwable e) {
}
@Override
public void onComplete() {
}
});
