do this public OrderDetailsAdapter(Context context, int resource,List<OrderDetails> orderList) { super(context, resource); this.context = context; this.resource = resource; this.orderList = orderList; } and this OrderDetailsAdapter orderDetailsAdapter = new OrderDetailsAdapter(this,R.layout.order_list_view_items,orderList);
