Thanks to Mikhali, I'm able to provide to you a complete running example.
Pay special attention on the comments in onBindViewHolder()
public class RecyclerViewAdapter extends RecyclerView.Adapter<RecyclerViewLedgerAdapter.ViewHolder>{

private final int TYPE_ITEM = 0;
private final int TYPE_DATE = 1;
private final int TYPE_TRANSACTION = 2;
private final int TYPE_PENDING = 3;
private HashMap<Integer, Integer> mElementTypes;
private List<Operation> mObjects;
private Context mContext;
private Utils.CURRENCIES mCurrencySelected; // Which currency is already selected
private boolean mCurrencyFilter; // Defines if a currency is already selected to apply filter
private Animation mAnimationUp;

public RecyclerViewLedgerAdapter(List<Operation> objects, Context context) {
mElementTypes = new HashMap<Integer, Integer>();
mObjects = objects;
mContext = context;
mCurrencyFilter = false;
mCurrencySelected = null;
mAnimationUp = AnimationUtils.loadAnimation(context, R.anim.slide_up);
