I solved this issue like this, create the adapter like this

package com.yubraj.sample.adapter;

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentStatePagerAdapter;

import com.yubaraj.sample.activities.RashiFragment;
import java.util.List;


public class PageSliderAdapter extends FragmentStatePagerAdapter {
    static String[] titleList = new String[] { "today",
            "this month", "this year" };
    List rashi;
    // private static String TAG = "pagerscreenslider";

    public PageSliderAdapter(FragmentManager fm, List rashiList) {
        super(fm);
        this.rashi = rashiList;
    }
    public void updateData(List rashisList){
        rashi.clear();
        this.rashi = rashisList;
        notifyDataSetChanged();
    }
    @Override
    public int getItemPosition(Object object) {
        // TODO Auto-generated method stub
        return POSITION_NONE;
    }

    @Override
    public Fragment getItem(int position) {
        Fragment fragment = new RashiFragment();
        Bundle bundle = new Bundle();
        bundle.putString("RASHI", rashi.get(position));
        bundle.putInt("RASHI_TYPE", position);
        fragment.setArguments(bundle);
        return fragment;
    }

    @Override
    public int getCount() {
        return titleList.length;
    }

    @Override
    public String getPageTitle(int position) {
        return titleList[position];
    }


}

Then from Your activity

List rashiCollection = getJSONFromDb(Dates);
adapter.updateData(rashiCollection);
