I've been looking at this tutorial for how to use Spinners but I'm now stuck.Currently when an item is selected from the spinner a toast is displayed with the choice, what I want to do instead is run a function to set the latitude and longitude to the selected country.The button "Set Location to Japan" works perfectly by calling the function "SetLocationJapan". I just want take this process and put it into the spinner so whenever a choice is made the latitude and longitude is updated.Here is the code I have currently
