Answer 1

To create RecyclerView with multiple view type just implement getItemViewType(), two different ViewHolders and take care of the viewType parameter in onCreateViewHolder() and bindViewHolder().

Short example:

public class MultipleViewTypesAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {

    private static final int VIEW_TYPE_FIRST  = 0;
    private static final int VIEW_TYPE_SECOND = 1;

    class ViewHolderFirst extends RecyclerView.ViewHolder {
        ...
    }

    class ViewHolderSecond extends RecyclerView.ViewHolder {
        ...
    }

    @Override
    int getItemViewType(int position) {
        return position % 2;
    }

    @Override
    public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        switch (viewType) {
            case VIEW_TYPE_FIRST: return new ViewHolderFirst(...);
            case VIEW_TYPE_SECOND: return new ViewHolderSecond(...);
            ...
        }
    }

    @Override
    public void bindViewHolder(RecyclerView.ViewHolder holder, int position) {
        switch (getItemViewType(position)) {
            case VIEW_TYPE_FIRST:
                ViewHolderFirst viewHolderFirst = (ViewHolderFirst)holder;
                ...
                break;
            case VIEW_TYPE_SECOND:
                ViewHolderSecond viewHolderSecond = (ViewHolderSecond)holder;
                ...
                break;
            ...
        }
    }
}
