Add Fragments dynamically to ViewPager

code implementation

List<Fragment> fragments = buildFragments();
ArrayList<String> categories = {"1", "2", "3", ..., "n"};
mPager = (ViewPager) v.findViewById(R.id.pager);
mPageAdapter = new MyFragmentPageAdapter(this,getSupportFragmentManager(), fragments, categories);
mPager.setAdapter(mPageAdapter);

//Add a new Fragment to the list with bundle
Bundle b = new Bundle();
b.putInt("position", i);
String title = "asd";
mPageAdapter.add(MyFragment.class, title, b);
mPageAdapter.notifyDataSetChanged();

FragmentPageAdapter

import java.util.ArrayList;
import java.util.List;

import android.content.Context;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;

public class MyFragmentPageAdapter extends FragmentPagerAdapter {

	public static int pos = 0;

	private List<Fragment> myFragments;
	private ArrayList<String> categories;
	private Context context;

	public MyFragmentPageAdapter(Context c, FragmentManager fragmentManager, List<Fragment> myFrags, ArrayList<String> cats) {
		super(fragmentManager);
		myFragments = myFrags;
		this.categories = cats;
		this.context = c;
	}

	@Override
	public Fragment getItem(int position) {

		return myFragments.get(position);

	}

	@Override
	public int getCount() {

		return myFragments.size();
	}

	@Override
	public CharSequence getPageTitle(int position) {

		setPos(position);
		return categories.get(position);
	}

	public static int getPos() {
		return pos;
	}

	public void add(Class<Fragment> c, String title, Bundle b) {
		myFragments.add(Fragment.instantiate(context,c.getName(),b));
		categories.add(title);
	}
	
	public static void setPos(int pos) {
		MyFragmentPageAdapter.pos = pos;
	}
}

Fragments list builder

private List<android.support.v4.app.Fragment> buildFragments() {
		List<android.support.v4.app.Fragment> fragments = new ArrayList<android.support.v4.app.Fragment>();
		for(int i = 0; i<categories.size(); i++) {
			Bundle b = new Bundle();
			b.putInt("position", i);
			fragments.add(Fragment.instantiate(this,MyPagerFragment.class.getName(),b));
		}

		return fragments;
	}

Was Really Helpful :)

I don't want to loose the page scrolled. I want to persist the scrolled page when I adds the new fragment to the end of the list. So it will not shows directly to user. Whenever user scrolls to the last item , he can understand that yeah there is new fragment added in the list.

Good
