                    layoutParams1.leftMargin = x_cord - 25;
                    layoutParams1.topMargin = y_cord - 75;
                    tv1.setLayoutParams(layoutParams1);
                    break;
                default:
                    break;

Relative layout also scroll as well imageview also drag properly.
without scroll bar imageview move well
