TransactionListView

DatabaseAdapter dbHelper = new DatabaseAdapter(this);

            TextView title = (TextView) view.findViewById(R.id.item_title);
            title.setText(cursor.getString(
                        cursor.getColumnIndex(DatabaseAdapter.KEY_BANKNAME)));

            TextView details = (TextView) view.findViewById(R.id.item_details);
            StringBuffer detailsText = new StringBuffer();

            int price = cursor.getInt(cursor.getColumnIndex(DatabaseAdapter.KEY_BALANCE));
            if (price > 0){
                detailsText.append("$"+price+".00");
            } else {
                detailsText.append("Price Unavailable");
            }
            String description = cursor.getString(cursor.getColumnIndex(
                                                    DatabaseAdapter.KEY_TYPE));
            if (description != null && description.length() > 0){
                detailsText.append(", "+description);
            }
            details.setText(detailsText.toString());

        }

    }
