How to add list of objects of Fragment to PagerAdapter

Question

I have PagerAdapter class that handle ScreenSlider. What i want is to add instance(objects of Fragment class) instead of adding multiple Fragments

Class where PagerAdapterClass is called:

    List<Fragment> fragments = new Vector<Fragment>();        

    fragments.add(Fragment.instantiate(this, Fragment1.class.getName()));// Here i want to add instance of class
    fragments.add(Fragment.instantiate(this, Fragment2.class.getName()));    

    this.mPagerAdapter  = new PagerAdapter2(super.getSupportFragmentManager(), fragments); //Constructor

    ViewPager pager = (ViewPager)findViewById(R.id.view_pager);

    pager.setAdapter(this.mPagerAdapter);

    pager.setCurrentItem(Proba.broj);

And here is PagerAdapter class:

public class PagerAdapter2 extends FragmentPagerAdapter

{

private List<Fragment> fragments;
/**
 * @param fm
 * @param fragments
 */
public PagerAdapter2(FragmentManager fm, List<Fragment> fragments) {
    super(fm);
    this.fragments = fragments;
}
/* (non-Javadoc)
 * @see android.support.v4.app.FragmentPagerAdapter#getItem(int)
 */
@Override
public Fragment getItem(int position)
{
    return this.fragments.get(position);
}

/* (non-Javadoc)
 * @see android.support.v4.view.PagerAdapter#getCount()
 */
@Override
public int getCount() {
    return this.fragments.size();
}

}

Add an instance then.

fragments.add(new Fragment1()) ;

Or if you need arguments

Fragment f = new Fragment1();
Bundle args1 = new Bundle() ;
// put into args1
f.setArguments(args1);
fragments.add(f) ;

Related: When Fragment.instantiate is preferable over MyFragment.newInstance or new MyFragment()

instead of adding multiple Fragments

You have to add multiple Fragments if you want multiple pages

But how to add another instace of Fragment1 with diffrent argumets? – smiljka Apr 09 '17 at 13:42
You copy paste that exact line again. You never used arguments in the question, so I don't know what you mean – OneCricketeer Apr 09 '17 at 13:44
Well this instances have diffrent arguments, same member class but with diffrent values.. – smiljka Apr 09 '17 at 13:46
