Is it possible to load different data in recycler-view?

Question

Java

I have a fragment with two buttons. Each of them now leads to a fragment with a recycler-view, however, we need to make sure that different data is loaded into the recycler-view depending on the selected button. Can this be done with a single fragment with recycler-view? Or do I need to create a second one for the second button?

Fragment code with buttons (now I use pictures instead of them, but the essence does not change)

ых данных в recycler-view

У меня есть фрагмент с двумя кнопками. Каждая из них сейчас ведет на фрагмент с recycler-view, однако надо сделать так, чтобы в recycler-view загружались разные данные в зависимости от выбранной кнопки. Можно ли это сделать с один фрагментом с recycler-view? Или нужно создавать второй для второй кнопки?

Код фрагмента с кнопками (для простоты просто поставил клик на картинки)

    ImageView imageView = (ImageView) view.findViewById(R.id.menu_image);
    Glide.with(this).load(R.drawable.cutting_coupon).into(imageView);
    imageView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            TestFragment newFragment = new TestFragment();
            ((AppCompatActivity) imageView.getContext()).getSupportFragmentManager().beginTransaction()
                    .replace(R.id.content_frame, newFragment)
                    .addToBackStack(null)
                    .commit();
        }
    });

    ImageView imageView1 = (ImageView) view.findViewById(R.id.menu_image1);
    Glide.with(this).load(R.drawable.sale).into(imageView1);
    imageView1.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            TestFragment newFragment = new TestFragment();
            ((AppCompatActivity) imageView.getContext()).getSupportFragmentManager().beginTransaction()
                    .replace(R.id.content_frame, newFragment)
                    .addToBackStack(null)
                    .commit();
        }
    });

Here is the snippet code with recycler-view

public class TestFragment extends Fragment {

private ArrayList<GalleryGridObject> galleryList = new ArrayList<GalleryGridObject>();
private TestAdapter mAdapter;
private RecyclerView recyclerView;

public TestFragment() {
    // Required empty public constructor
}


@Override
public View onCreateView(@NonNull LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Inflate the layout for this fragment
    View view = inflater.inflate(R.layout.fragment_test, container, false);

    recyclerView = (RecyclerView) view.findViewById(R.id.my_recycler_view);

    mAdapter = new TestAdapter(this, galleryList);
    LinearLayoutManager layoutManager = new LinearLayoutManager(getActivity());
    recyclerView.setLayoutManager(layoutManager);
    recyclerView.setAdapter(mAdapter);

    recyclerView.setHasFixedSize(true);

    prepareGalleryData();

    return view;
}

private void prepareGalleryData()
{
    GalleryGridObject gallery = new GalleryGridObject(R.drawable.test);
    galleryList.add(gallery);

    gallery = new GalleryGridObject(R.drawable.test);
    galleryList.add(gallery);

    gallery = new GalleryGridObject(R.drawable.test);
    galleryList.add(gallery);

    gallery = new GalleryGridObject(R.drawable.test);
    galleryList.add(gallery);

    gallery = new GalleryGridObject(R.drawable.test);
    galleryList.add(gallery);

    gallery = new GalleryGridObject(R.drawable.test);
    galleryList.add(gallery);

    gallery = new GalleryGridObject(R.drawable.test);
    galleryList.add(gallery);

    gallery = new GalleryGridObject(R.drawable.test);
    galleryList.add(gallery);

    mAdapter.notifyDataSetChanged();
}

Answer 1

Can. Google towards the adapter, there is an overridden method
public int getItemViewType (int position)
in which you can determine the type of the returned item. For each type, you need to describe your own ViewHolder and then in onBindViewHolder (final ViewHolder holder, final int position) bind the desired one (as you can see, both the type and the binding are tied to the position)
