Android - How to pick numbers from a generated list?

This question is based on my other question, make sure to take a look at it: Android - Generate non-repetitive random numbers

I have a collection that shuffles, but how can I pick the numbers one by one after "next" button is pressed?

ArrayList<Integer> list = new ArrayList<Integer>();
    for (int i=1; i<11; i++) {
        list.add(new Integer(i));
    }
    Collections.shuffle(list);

This code is executed when the app is opened.

qid = 

This code is executed after "Next" button is pressed.

I'm confused on what the question id(qid) should be.

Thanks in advance!
