                .findViewById(R.id.productName);
        totalCountHolder.productQuantityView = (EditText) totalView

        }

    }

}

This is my Adapter class

When you scroll down or up the listview, by default android system everytime creates new row and destroy the previous rows because of this you lost your data when you scroll. Try to save the data of edittext in SharedPreferences with key as position of row and later retrieve the data from sharedpreferences. Every time you have to check in the beginning of getView() method that current position is saved already in sharedpreferences or not. If find set that value to edittext otherwise not.
