Recyclerview with different type

Question

Hi guys I'm trying to populate RecyclverView with different collections.. For example I got 2 list lets say customer list and supplier list.

What I want to achieve is :

• customer header

---

• Customer 1

• Customer 2

---

• supplier header

---

• Supplier 1

• Supplier 2

Is that possible? Thanks.
Sorry for my English

You can make Section in recyclerview like this way

public class MainAdapter extends SectionedRecyclerViewAdapter<MainAdapter.MainVH> {

    @Override
    public int getSectionCount() {
        return 20; // number of sections.
    }

    @Override
    public int getItemCount(int section) {
        return 8; // number of items in section (section index is parameter).
    }

    @Override
    public void onBindHeaderViewHolder(MainVH holder, int section) {
        // Setup header view.
    }

    @Override
    public void onBindViewHolder(MainVH holder, int section, int relativePosition, int absolutePosition) {
        // Setup non-header view.
        // 'section' is section index.
        // 'relativePosition' is index in this section.
        // 'absolutePosition' is index out of all non-header items.
        // See sample project for a visual of how these indices work.
    }

    @Override
    public MainVH onCreateViewHolder(ViewGroup parent, int viewType) {
        // Change inflated layout based on 'header'. 
        View v = LayoutInflater.from(parent.getContext())
                .inflate(viewType == VIEW_TYPE_HEADER ? R.layout.header : R.layout.normal, parent, false);
        return new MainVH(v);
    }

    public static class MainVH extends RecyclerView.ViewHolder {

        public MainVH(View itemView) {
            super(itemView);
            // Setup view holder.
            // You'd want some views to be optional, e.g. for header vs. normal.
        }
    }
}

It's possible to do this with RecyclerView, you should override getItemViewType() method.

Like this:

private class CustomAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {

    private static final int TYPE_1 = 1;
    private static final int TYPE_2 = 2;
    private static final int TYPE_3 = 3;
    // more types...

    @Override
    public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        switch (viewType) {
            case TYPE_1:
                break;
            case TYPE_2:
                break;
            case TYPE_3:
                break;
        }
    }

    @Override
    public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
        switch (getItemViewType(position)) {
            case TYPE_1:
                break;
            case TYPE_2:
                break;
            case TYPE_3:
                break;
        }
    }

    @Override
    public int getItemViewType(int position) {
        if(position == 1) {
            return TYPE_1;
        } else if(position == 2) {
            return TYPE_2;
        } else 
            return TYPE_3
    }

    @Override
    public int getItemCount() {
        return 10;
    }
}
