Use FragmentStatePagerAdapter instead of FragmentPagerAdapter if you want to recreate or reload fragment on index basis For example if you want to reload fragment other than FirstFragment, you can check instance and return position like this

 public int getItemPosition(Object item) {
    if(item instanceof FirstFragment){
       return 0;
    }
    return POSITION_NONE;
 }
