Update ViewPager dynamically?

Question

I can\'t update the content in ViewPager.

What is the correct usage of methods instantiateItem() and getItem() in FragmentPagerAdapter class?

I was using onl

Answer 1

I slightly modified the solution provided by Bill Phillips to suit my needs

private class PagerAdapter extends FragmentStatePagerAdapter{
    Bundle oBundle;
    FragmentManager oFragmentManager;
    ArrayList oPooledFragments;

public PagerAdapter(FragmentManager fm) {
    super(fm);
    oFragmentManager=fm;

    }
@Override
public int getItemPosition(Object object) {

    Fragment oFragment=(Fragment)object;
    oPooledFragments=new ArrayList<>(oFragmentManager.getFragments());
    if(oPooledFragments.contains(oFragment))
        return POSITION_NONE;
    else
        return POSITION_UNCHANGED;
    } 
}

so that the getItemPosition() returns POSITION_NONE only for those fragments which are currently in the FragmentManager when getItemPosition is called. (Note that this FragmentStatePager and the ViewPager associated with it are contained in a Fragment not in a Activity)
