FragmentPagerAdapter reload the processed fragment on the tabs based on the parameter value

i have created my project using this material design example. i have modified the code and now i have 5 tabs now. And now i have created 5 fragment classes and loading it on the view pager. now what i want is, i want to pass the selected sliding menu position as a parameter to the fragment which i am loading. Here the problem is, i can pass the parameter(using Bundle) to the FragmentPagerAdapter , but it is not reloading the fragments based on the parameter i'm passing! the thing is it is not even executing the page loading part in FragmentPagerAdapter!

How can i reload my fragments on the Taps based on the parameter i'm passing? FYI, based on the parameter value that i'm passing, i'm doing some processing and i want to show the processed fragment page on the tabs.

please help this is the series problem i'm facing it right now! Thanks in advance :)

Here is my adapter code

public class ViewPagerAdapter1 extends FragmentPagerAdapter { final int PAGE_COUNT =6; private String titles[] ; Bundle b2; public ViewPagerAdapter1(FragmentManager fm, String[] titles2, Bundle b) { super(fm); titles=titles2; this.b2=b; } @Override public Fragment getItem(int position) { switch (position) { case 0: return new GridTableActivity(); case 1: Bundle selected1 = new Bundle(); selected1.putInt("selected",0); GridTableActivity gridTableActivity = new GridTableActivity(); gridTableActivity.setArguments(selected1); return gridTableActivity; case 2: Bundle selected2 = new Bundle(); selected2.putInt("selected",0); DownTimeTable downTimeTable = new DownTimeTable(); downTimeTable.setArguments(selected2); return downTimeTable; case 3: Bundle selected3 = new Bundle(); selected3.putInt("selected",0); GraphActivity graphActivity = new GraphActivity(); graphActivity.setArguments(selected3); return graphActivity; case 4: Bundle selected4 = new Bundle(); selected4.putInt("selected",0); BarChartActivity barChartActivity = new BarChartActivity(); barChartActivity.setArguments(selected4); return barChartActivity; case 5: Bundle selected5 = new Bundle(); selected5.putInt("selected",0); PieChartActivity pieChartActivity = new PieChartActivity(); pieChartActivity.setArguments(selected5); return pieChartActivity; } return null; } public CharSequence getPageTitle(int position) { return titles[position]; } @Override public int getCount() { return PAGE_COUNT; }}

currently i'm doing like this! i have 9 items on the drawer & created 9 different adapter classes!(so sad sry abt this! :|)

public class SampleActivity extends ActionBarActivity { private DrawerLayout mDrawerLayout; private ActionBarDrawerToggle drawerToggle; private ListView mDrawerList; ViewPager pager1,pager2,pager3,pager4,pager5,pager6,pager7,pager8,pager9;
