Use inside a fragment?

[jaambee]

Hi, i have this code on my fragment:

public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        fragmentHomeBinding = DataBindingUtil.inflate(LayoutInflater.from(getContext()), R.layout.fragment_home, container, false);
        fragmentHomeBinding.rv.setLayoutManager(new LinearLayoutManager(getContext()));
        fragmentHomeBinding.rv.setHasFixedSize(true);
        //Dummy DataSet
        mCompositeSubscription.add(HaipService.getMyPendingCampaigns()
                .subscribeOn(Schedulers.io())
                .observeOn(AndroidSchedulers.mainThread())
                .flatMap(campaigns -> {
                    pending = new RxDataSource<>(campaigns);
                    return pending.<MainItemBinding>bindRecyclerView(fragmentHomeBinding.rv, R.layout.main_item);
                })
                .doOnNext(campaignMainItemBindingSimpleViewHolder -> {
                    fragmentHomeBinding.rv.setAdapter(pending.getRxAdapter());
                })
                .subscribe(viewHolder -> {
                    MainItemBinding item = viewHolder.getViewDataBinding();
                    Campaign campaign = viewHolder.getItem();
                    Log.d("I'm here", campaign.getName());

                    Picasso.with(getContext()).load(campaign.getLogo()).fit().centerInside().into(item.brandImage);
                    Picasso.with(getContext()).load(campaign.getImage())
                            .fit().centerCrop().into(item.campaignImage);
                    item.brandName.setText(campaign.getName());
                    item.progressBar.setProgress(campaign.getCompleteStatus());
                    item.completedPercent.setText(String.valueOf(campaign.getCompleteStatus()) + "%");
                }, Throwable::printStackTrace));
        return fragmentHomeBinding.getRoot();

    }

but when I run the app, i'm only get

E/RecyclerView: No adapter attached; skipping layout

If I test the same code on an Activity, it works (changing DataBindingUtil.inflate by DataBindingUtil.setContentView).

Is this the correct way to bind a recyclerView inside a fragment?

Hi! I'll look into it... You're using the adapter correctly... Just a few pointers for now, that you can check...
While inflating the Fragment through Databinding, you don't need to create a new Inflater... You do get an inflater object in onCreateView...
fragmentHomeBinding = DataBindingUtil.inflate(inflater, R.layout.fragment_home, container, false);
Secondly... You also don't need to call setAdapter explicitly on the RecyclerView... bindRecyclerView method takes care of that also... Hence your doOnNext can be omitted...
Anyway... I'll see if I can fix the No adapter attached issue, and will let you know soon...

I make the corrections, but i get the same result. My fragment is inside of a ViewPager. Can be this the problem ?
