Example 11 with Observer

use of rx.Observer in project wh-app-android by WhiteHouse.

the class SearchFragment method submitQuery.

public void submitQuery(String query) {
    showList(false);
    showProgress(true);
    if (mSearchSub != null) {
        mSearchSub.unsubscribe();
    }
    if (!NetworkUtils.checkNetworkAvailable(getActivity())) {
        showProgress(false);
        Toast.makeText(getActivity(), R.string.no_network, Toast.LENGTH_SHORT).show();
        return;
    }
    mSearchSub = AndroidObservable.bindFragment(this, SearchManager.get().search(query).first().map(searchResults -> {
        List<SearchResult> list = new ArrayList<>();
        SearchResult result;
        if (searchResults.boosted_results() != null) {

        }
        return list;
    }).subscribeOn(Schedulers.newThread())).subscribe(new Observer<List<SearchResult>>() {

        @Override
        public void onCompleted() {
            showProgress(false);
            showList(true);

        @Override

        @Override

            getAdapter().clear();

Example 12 with Observer

use of rx.Observer in project scalecube by scalecube.

the class RemoteServiceInstance method listen.

@Override
public Observable<Message> listen(final Message request) {
    final String cid = request.correlationId();
    AtomicReference<Subscription> subscription = new AtomicReference<>();
    Observable<Message> observer = transportObservable.doOnUnsubscribe(() -> {
        Message unsubscribeRequest = Messages.asUnsubscribeRequest(cid);
        LOGGER.info("sending remote unsubscribed event: {}", unsubscribeRequest);
        subscription.get().unsubscribe();
        sendRemote(unsubscribeRequest);
    });
    Subscription sub = observer.filter(message -> message.correlationId().equals(cid)).subscribe(onNext -> {
        serviceResponses.onNext(onNext);
    });
    subscription.set(sub);
    sendRemote(request);
    return serviceResponses;

    }, Emitter.BackpressureMode.BUFFER);
