Refreshing fragments in ViewPager

Question

I have a fragment activity with a ViewPager in it, and this fragment activity should send data to the fragments inside of the pager(so the fragments can display the search results). So my issue is that when I swipe to a fragment it doesnt refresh - I need to swipe few more times between the fragments so they show the new data. Can some tell me what is the propper approach to do this?

Here is my code:

//first i init the widgets
private void initWidgets() {
        bundle = new Bundle();
        progressBar = (ProgressBar) findViewById(R.id.search_progressBar);
        viewPager = (ViewPager) findViewById(R.id.search_viewpager);
        titleStrip = (PagerTabStrip) findViewById(R.id.search_titlestrip);
        myFragmentPagerAdapter = new ScreenSlidePagerAdapter(getSupportFragmentManager());
        viewPager.setAdapter(myFragmentPagerAdapter);
        viewPager.setCurrentItem(1001);
        titleStrip.setDrawFullUnderline(true);
    }

//then after writing some text in the search i call this function//
private void search(String keyWord) {

        try {
            bundle.putString(IntentConstants.KEYWORD, searchEt.getText().toString());
            myFragmentPagerAdapter.notifyDataSetChanged();

        } catch (Exception e) {
            e.printStackTrace();
        }
    }
/*and then the bundle is passed to the fragments - this is in a subclass of the fragmentActivity*/
private class ScreenSlidePagerAdapter extends FragmentStatePagerAdapter {

        public ScreenSlidePagerAdapter(FragmentManager fm) {
            super(fm);
        }

        @Override
        public Fragment getItem(int position) {

            switch (position % PAGE_TITLES.length) {
//                community
                case 0:
                    CommunitySearchFragment f = new CommunitySearchFragment();
                    f.setArguments(bundle);
                    return f;
                //My Clipbords Clipboardadater  FragmentSearchMyClipboards
                case 1:


                    FragmentSearchMyClipboards fragment = new FragmentSearchMyClipboards();
                    fragment.setArguments(bundle);
                    return fragment;

//                My clips
                case 2:
                    MyClipsFragment f2 = new MyClipsFragment();
                    f2.setArguments(bundle);
                    return f2;
//                members
                case 3:
                    MembersFragment f3 = new MembersFragment();
                    f3.setArguments(bundle);
                    return f3;
            }

            return null;
        }


        @Override
        public CharSequence getPageTitle(int position) {
            return PAGE_TITLES[position % PAGE_TITLES.length];
        }

        @Override
        public int getCount() {
            return 5000;
        }
    }

and here is one of my fragments as a reference to what i do:

public class MyClipsFragment extends Fragment {
    ArrayList<ClipsVO> clipsArray;
    private View mView;
    private ListView list;

    private MyClipboardSearchAdapter adapter;
    private ArrayList<ClipsVO> rClipsArray;

    private ProgressBar progress;

    @Override
    public void onAPIResponse(ResultVO result) {
        super.onAPIResponse(result);
        if (result.getApiMethod().equals(ClipixServer.APIMETHOD_SEARCHCLIP)) {
            clipsArray = (ArrayList<ClipsVO>) result.getData();
            int userId = Integer.parseInt(UserProfile.getinstance().getUserData().getUserId());

            if (clipsArray.size() > 0) {
                ArrayList<ClipsVO> rClipsArray = new ArrayList<ClipsVO>();
                for (int i = 0; i < clipsArray.size(); i++) {
                    ClipsVO clip = clipsArray.get(i);
                    if (clip.getOwnerUserId().equals(userId + "")) {
                        if (rClipsArray.size() == 0) {
                            //Add header for the Current User's clips in the result
                            ClipsVO headerClip = new ClipsVO();
                            headerClip.setHeader(true);
                            headerClip.setDescription(getLocalizationString("lblCommunityMyClips"));
                            rClipsArray.add(headerClip);
                        }
                        rClipsArray.add(clipsArray.remove(i));
                        i--;
                    }
                }
                if (clipsArray.size() > 0) {
                    //Add header for the other Clipboards in the result
                    ClipsVO headerClip = new ClipsVO();
                    headerClip.setHeader(true);
                    headerClip.setDescription(getLocalizationString("lblClips"));
                    rClipsArray.add(headerClip);
                    rClipsArray.addAll(clipsArray);
                }
            }
            this.rClipsArray = clipsArray;
            if (getActivity() != null)
                setupData();
        }
    }

    private void setupData() {
        adapter = new MyClipboardSearchAdapter(getActivity(), rClipsArray);
        list.setAdapter(adapter);
        TextView emptyTxt = (TextView) mView.findViewById(R.id.empty);
        emptyTxt.setText(getLocalizationString("txtPeopleSearchNoResult"));
        progress.setVisibility(View.GONE);
        emptyTxt.setTextSize(14);
        list.setEmptyView(emptyTxt);
        list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> adapterView, View view, int position, long l) {
                Object itemObject = rClipsArray.get(position);
                ArrayList<ClipsVO> clipsList = new ArrayList<ClipsVO>();
                ClipsVO clipVO = (ClipsVO) itemObject;
                clipsList.add(clipVO);
                Intent intent = new Intent(getActivity(), ClipsListDetailActivity.class);

                intent.putExtra(IntentConstants.CLIP_DATA, clipVO);

        });


    }

Answer 1

Method 1:

ViewPager loads the fragment by default 1 in the both the sides. so, it can have 3 fragments already loaded in the adapter.

try using the method below

public void setOffscreenPageLimit (int limit)

as

viewPager.setOffscreenPageLimit(0);

this will allow to load the fragments always dynamically.

Method 2:

On load of fragment [onAttachActivity] you can refresh the view [set the view contents]
