made a lot of progress today. got the list view to refresh on delete. also added an empty view text view so the user knows the list is empty. added a button to calculate the trip in case the user doesn't use the enter button on the keyboard. also made sure the keyboard goes down when the trip results tab is clicked. the sort spinner is working how it should. really happy with where the app is. next step is to reach out to someone on fiver and have custom buttons and an icon made. shortly thereafter i can clean up the code and get it ready for the Play Store.
