FragmentPagerAdapter.getItem (int) shows wrong Fragment

Question

My FragmentPagerAdapter carries the 3 pages of ViewPager.OffScreenPageLimit and always displays the last loaded page

I use ViewPager to display Fragments.

my ViewPager

private static final int MONTH_SIZE = 12;

            viewPager.setAdapter(new CalendarFragmentPagerAdapter(getChildFragmentManager()));
        viewPager.setCurrentItem(GregorianCalendar.getInstance().get(Calendar.MONTH));
        viewPager.setClickable(true);
        viewPager.setSaveEnabled(false);
        viewPager.setOffscreenPageLimit(1);

My FragmentPageAdapter:

    public class CalendarFragmentPagerAdapter extends FragmentPagerAdapter {

    /**
     * @param fm
     */
    public CalendarFragmentPagerAdapter(FragmentManager fm) {
        super(fm);
    }

    /**
     */
    @Override
    public Fragment getItem(int pageRequest) {
        return new CalendarFragment(pageRequest);
    }

    /**
     */
    @Override
    public int getCount() {
        return MONTH_SIZE - 1;
    }

    /**
     */
    @Override
    public CharSequence getPageTitle(int position) {
        switch (position) {

        case 0:
            return getString(R.string.monthJanuary);

        case 1:
            return getString(R.string.monthFebruary);

        case 2:
            return getString(R.string.monthMarch);

        case 3:
            return getString(R.string.monthApril);

        case 4:
            return getString(R.string.monthMay);

        case 5:
            return getString(R.string.monthJune);

        case 6:
            return getString(R.string.monthJuly);

        case 7:
            return getString(R.string.monthAugust);

        case 8:
            return getString(R.string.monthSeptember);

        case 9:
            return getString(R.string.monthOctober);

        case 10:
            return getString(R.string.monthNovember);

        case 11:
            return getString(R.string.monthDecember);

        default:
            return "";
        }
    }

    /**
     * @hide
     */
    @Override
    public int getItemPosition(Object object) {
        return POSITION_NONE;
    }
}

My Fragment:

// Nothing especial
    List<CalendarEntry> events = getEvents(indexByCalendarFragmentPagerAdapter);

        listView = (ListView) view.findViewById(R.id.listView_calendar_screen);

        listView.setAdapter(new CalendarCustomAdapter(getActivity().getBaseContext(), events));

        listView.setClickable(true);

The error is e.g. displays in the month of May, the events of February

Already tried several ways and could not solve the problem, can someone help me?

Becuase you set the count @Override public int getCount() { return MONTH_SIZE - 1; } Remove -1 — wSakly, Jun 03 '14 at 14:52
MONTH_SIZE it is a constant, the number of months of the year, I had forgotten to put her — Grandpa, Jun 03 '14 at 15:24
After changing to MONTH_SIZE keeps skipping a few pages. For example, displays in the month of May, the events of February — Grandpa, Jun 03 '14 at 15:34

simply change this code or function called getCount() to :

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

put events.length at getCount() will change the size of ViewPager to the number of events of the month – Grandpa Jun 03 '14 at 15:26

I solved with my own PagerAdapter. I used the example code found on the blog Eilfa
