Merge this:

private long previousItemId = 0;

@Override
public long getItemId(int position) {
    long nextItemId = random.nextInt(Integer.MAX_VALUE);
    while(previousItemId == nextItemId) {
        nextItemId = random.nextInt(Integer.MAX_VALUE);
    }
    previousItemId = nextItemId;
    return nextItemId;
}

With this answer:

public class SpinnerInteractionListener
        implements AdapterView.OnItemSelectedListener, View.OnTouchListener {

    private AdapterView.OnItemSelectedListener onItemSelectedListener;

    public SpinnerInteractionListener(AdapterView.OnItemSelectedListener selectedListener) {
        this.onItemSelectedListener = selectedListener;
    }

    boolean userSelect = false;

    @Override
    public boolean onTouch(View v, MotionEvent event) {
        userSelect = true;
        return false;
    }

    @Override
    public void onItemSelected(AdapterView parent, View view, int pos, long id) {
        if(userSelect) {
            onItemSelectedListener.onItemSelected(parent, view, pos, id);
            userSelect = false;
        }
    }

    @Override
    public void onNothingSelected(AdapterView parent) {
        if(userSelect) {
            onItemSelectedListener.onNothingSelected(parent);
            userSelect = false;
        }
    }
}
