Answer 1

You can't add data to application resources programmatically. Resources are part of compiled, packed and signed APK package and therefore can't be modified. What are you trying to achieve?

Answer 2

You can't add things to resources programmatically. But a Spinner doesn't need to go off a resource file. Use an in memory list of items, and modify that.

Answer 3

If try to add data in spinner programmtically.

there is only one way use database like #firebase which update realtime data.

"without database it not possible."
