ViewPager data lost when coming back from next screen

I am using a ViewPager in my application and I have three tabs in it; I am using ViewPager inside a fragment. Now my problem here is, I am getting data correctly while loading the application, but when I go next page and then back to ViewPager, the data is lost and tabs are not working. Please assist me. Below is my code:

import com.devpoint.rprtjobs.R;

import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentTabHost;

public class MainActivity extends Fragment {

   // Declaring Your View and Variables

   Toolbar toolbar;
   ViewPager pager;
   SwipeViewPagerAdapter adapter;
   SlidingTabLayout tabs;
   CharSequence Titles[]={"OnGoing","UpComing","Expired"};
   int Numboftabs =3;
private View rootView;

   @SuppressWarnings("deprecation")
public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        try {
            rootView = inflater.inflate(R.layout.activity_main,
                    container, false);


       adapter =  new SwipeViewPagerAdapter(getActivity().getSupportFragmentManager(),Titles,Numboftabs);

       // Assigning ViewPager View and setting the adapter
       pager = (ViewPager) rootView.findViewById(R.id.pager);
       pager.setAdapter(adapter);

       // Assiging the Sliding Tab Layout View
       tabs = (SlidingTabLayout) rootView.findViewById(R.id.tabs);
       tabs.setDistributeEvenly(true); // To make the Tabs Fixed set this true, This makes the tabs Space Evenly in Available width

       // Setting Custom Color for the Scroll bar indicator of the Tab View
       tabs.setCustomTabColorizer(new SlidingTabLayout.TabColorizer() {
           @Override
           public int getIndicatorColor(int position) {
               return getResources().getColor(R.color.tabsScrollColor);
           }
       });

       // Setting the ViewPager For the SlidingTabsLayout
       tabs.setViewPager(pager);

       pager.setOffscreenPageLimit(3);

       pager.setOnPageChangeListener(new OnPageChangeListener() {
            public void onPageScrollStateChanged(int state) {}
            public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {}

            public void onPageSelected(int position) {

                if(position ==0)
                {
                    SwipeViewPagerAdapter.Pagename = "ListOnGoing";
                }
                else if(position ==1)
                {
                    SwipeViewPagerAdapter.Pagename = "ListUpComing"; 
                }
                else if(position ==2)
                {
                    SwipeViewPagerAdapter.Pagename = "ListExpired";
                }

                }
        });


   }
        catch(Exception e)
        {
            e.printStackTrace();
        }
        return rootView;

   }

}

Here is my adapter:

  • Animating layouts using the “animateLayoutChanges” attribute in XML
  • Is it better code practice to register a receiver in manifest or in code?
  • Must Android app names be unique?
  • How to have a Lollipop switch button
  • Using the button tag, can I customize the button?
  • When to request permissions with Facebook's new Android SDK 3.0?

    After a little reasearch i got solution for my problem,that i just called getChildFragmentManager() instead of getactivity().getSupportFragmentmanager().This solved my issue.Thanks StackOverFlow

    In your adapter extend FragmentStatePagerAdapter instead of FragmentPagerAdapter it will solve your problem and if you are using the ViewPager inside a fragment then you need to use getChildFragmentManager() instead of getActivity().getSupportFragmentManager(). let me know if you have any problem.

    Hope this helps you 🙂

    public float getPageWidth(int position)
    {
    if (position == 0 || position == 2)
    {
    return 0.8f;
    }
    return 1f;
    }
    
    pager = (ViewPager) rootView.findViewById(R.id.pager);
    pager.setOffscreenPageLimit(2);// no of fragments
