How to dynamically change the Spinner's items

Question

I have two spinners. Country and City. I want to dynamically change the City's values upon Country selection. I know how to create and initialize the values of Country but don't know how to set and change the City's values.

Any guidance is appreciated.

UPDATES1 The problem is, I don't have idea on how to update the content of City Spinner. I know listener and other basics on how to create a fixed spinner.

Answer 1

For the second spinner, use an Adapter over a List<String> (or whatever your City representation is). After changing the contents of the list, call notifyDataSetChanged on the adapter, and that will do.
