我正在尝试使用 RxJava、RxAndroid 和 Mosby3 将两种表单插入组合在一起,但我找不到让它工作的方法。
我的结构:
public final class CheckinIntent {
private final CheckinCommand checkinCommand;
private final Bitmap signature;
public CheckinIntent(CheckinCommand checkinCommand, Bitmap signature) {
this.checkinCommand = checkinCommand;
this.signature = signature;
}
public CheckinCommand getCheckinCommand() {
return checkinCommand;
}
public Bitmap getSignature() {
return signature;
}
}
我在哪里触发我的意图(MVI 模式):
final Observable<Bitmap> signatureObservable = Observable.just(BitmapFactory.decodeFile(storage.getFile("signs", booking.getBookingId()).getAbsolutePath()));
final Observable<CheckinCommand> checkinCommandObservable = Observable.just(new CheckinCommand(booking.getBookingId(), booking.getUserId(), booking.getPartnerId(), userDetailsTextView.getText().toString(), "google.com"));
final Observable<CheckinIntent> intentObservable = Observable.zip(signatureObservable, checkinCommandObservable, (image, command) -> new CheckinIntent(command, image));
return saveButtonClickObservable
.flatMap(bla -> intentObservable);
并将它们绑定在一起:
@Override
protected void bindIntents() {
Observable<CheckinViewState> checkinViewStateObservable =
intent(CheckinView::sendCheckin)
.flatMap(checkinIntent -> imageRepository.uploadImage(checkinIntent.getSignature())
.flatMap(command -> bookingRepository.doCheckin(command) <------ PROBLEM HERE, HOW CAN I ACCESS THE COMMAND FROM ABOVE ??
.subscribeOn(Schedulers.from(threadExecutor))
.map(CheckinViewState.Success::new)
.cast(CheckinViewState.class)
.startWith(new CheckinViewState.LoadingState())
.onErrorReturn(CheckinViewState.ErrorState::new))
.observeOn(postExecutionThread.getScheduler());
subscribeViewState(checkinViewStateObservable, CheckinView::render);
}
Observable<CnhImageResponse> uploadImage(Bitmap bitmap);
我的问题是,我的 uploadImage 返回一个以字符串结尾的内部结构,但是,如何获取返回的字符串,将其添加到我的command
对象(在此对象中设置返回的 URL)并继续流程(将我的命令发送到云端) ?
谢谢!
