Android add and remove values from a spinner to a container

Question

I'm developing an android aplication and I want to do something like this:

• I want to be able to pick values from a dropdown list (spinner) and add them to a container (like a shopping basket)
  
• So that way I can be able to add and remove items from the container.

This should work like a form, and at the end, should return a list of items on the "container"
