Based on that value, Adapter should set the down arrow or up arrow

                Log。v("up", "up");
            } else {

            }
            Log。v("i=", i + " ,updown=" + updown[i]);
            i++;
        }

        holder。txtFirst。setText(map。get(FIRST_COLUMN));
        holder。txtSecond。setText(map。get(SECOND_COLUMN));
        holder。txtThird。setText(map。get(THIRD_COLUMN));
        return convertView;
    }

。

Log is showing correct data but arrow is getting displayed in only 1st row。 i。e。 if Last value of list is positive, it shows up arrow to 1st row and if Last value of list is negative, it shows down arrow to 1st row。。。
