private final int ACTIVE_VIEW=1;
private final int INACTIVE_VIEW=2;
private final int SUBHEADER_VIEW=3;
@Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
if(viewType == ACTIVE_VIEW) {
View v = getLayoutInflater().inflate(R.layout.active_item, parent, false);
return new ActiveItemViewHolder(v,
(CheckBox)v.findViewById(R.id.item_status),
