FragmentPagerAdapter getItem is not called

I am not able to reuse fragment in FragmentPagerAdapter.. Using destroyItem() method, It is deleting the fragment but still does not called getItem() again..There are just 2-3 Images so I am using FragmentPagerAdapter Instead of FragmentStatePagerAdapter..

public class ExamplePagerAdapter extends FragmentPagerAdapter {

ArrayList < String > urls;
int size = 0;
public ExamplePagerAdapter(FragmentManager fm, ArrayList < String > res) {
super(fm);
urls = res;
size = urls.size();
}

@Override
public int getCount() {
if (urls == null) {
return 0;
} else {
return size;
}

}

@Override
public void destroyItem(ViewGroup container, int position, Object object) {
FragmentManager manager = ((Fragment) object).getFragmentManager();
FragmentTransaction trans = manager.beginTransaction();
trans.remove((Fragment) object);
trans.commit();
}

@Override
public Fragment getItem(int position) {

Fragment fragment = new FloorPlanFragment();
Bundle b = new Bundle();
b.putInt("p", position);
b.putString("image", urls.get(position));
Log.i("image", "" + urls.get(position));
fragment.setArguments(b);
return fragment;
}
}


And In FragmentActivity,

pager.setAdapter(new ExamplePagerAdapter(getSupportFragmentManager(), res2));

Answer

KISS Answer

Simple use FragmentStatePagerAdapter instead of FragmentPagerAdapter

I got the answer.. Firstly I thought to delete this question as I am doing a very silly mistake but this answer will help someone who is facing the same problem that Instead of FragmentPagerAdapter, use FragmentStatePagerAdapter..
