Unable to capture random id in view pager

I have implemented view pager with cursor pager adapter as in it is fetching the data in random order from SQLite and displaying the same in pager's fragment. It is working absolutely fine. Now I want to give user an option to mark these quotes as favourite. My approach is to set a flag against quote_id in database and have achieved this too successfully but the problem is whenever i swipe right or left and wants to unfavorite the 'favorite one' quote then it is not working because id on swipe is incorrect as in if i am 3rd quote then id of 1st quote is getting displayed. Need your help in resolving the same.

    // Inflate the layout for this fragment
    View rootView = inflater.inflate(R.layout.fragment_item_pager, container, false);

    // Instantiate a ViewPager and a PagerAdapter in app.
    mPager = (ViewPager) rootView.findViewById(R.id.pager);
    getLoaderManager().initLoader(-5, null, this);
    adapter = new CursorPagerAdapter(getFragmentManager(), null);
    mPager.setAdapter(adapter);
    return rootView;
}

@Override
public Loader<Cursor> onCreateLoader(int id, Bundle args) {

    CursorLoader loader = new CursorLoader(getActivity(),

            null, 
            null, 
            null, 
            "RANDOM()");

    return loader;
}

@Override

    adapter.swapCursor(data);
