10. The displayMessage Method

INSTRUCTOR NOTE:

The end goal should look something like this:

In the activity_main.xml layout:

1. Change PRICE label to ORDER SUMMARY
2. Change the TextView for price value to have an ID of @+id/order_summary_text_view.

In MainActivity.java, in the displayMessage(String message) method:

3. Change variable name from priceTextView to orderSummaryTextView.
4. Change R.id.price_text_view to R.id.order_summary_text_view.

In MainActivity.java:

5. Remember to delete the displayPrice() method because we don’t need that anymore.
