Android: limit fragments loading with a viewPager

问题

I have 3 fragments that are managed by an FragmentPagerAdapter, set to a viewPager.

I want to load fragments one by one, but when the onCreate method of FragmentActivity is executed, the 2 first fragments are executed (onCreateView method).

I have tried to limit fragments loading with the setOffscreenPageLimit method but nothing change.

mPagerAdapter =  new MyPagerAdapter(super.getSupportFragmentManager(), fragments);
pager = (ViewPager) super.findViewById(R.id.tabviewpager);
pager.setOffscreenPageLimit(0);
pager.setAdapter(this.mPagerAdapter);

Thank you for your help .

The minimum for OffscreenPageLimit is set to 1 in the ViewPager source code:

private static final int DEFAULT_OFFSCREEN_PAGES = 1;
....
public void setOffscreenPageLimit(int limit) {
    if (limit < DEFAULT_OFFSCREEN_PAGES) {
        Log.w(TAG, "Requested offscreen page limit " + limit + " too small; defaulting to " +
                DEFAULT_OFFSCREEN_PAGES);
        limit = DEFAULT_OFFSCREEN_PAGES;
    }
    if (limit != mOffscreenPageLimit) {
        mOffscreenPageLimit = limit;
        populate();
    }
}
