Load only one Fragment in ViewPager

问题

I have used ViewPager with Fragment.
But it loads two pages at time.
Is there any way to load only one page in viewpager ?

回答1:

This might be the thing you are looking for:

  mPager.setOffscreenPageLimit(n); // where n is the number of offscreen pages you want to load.

**The minimum value of it can be "1" as you said. ** check this link and also read the comments.

回答2:

setOffScreenPageLimit method has a limit of minimum 1. If you'll try to set smaller limit than this, it will use its default value which is 1.

You can try to do manual your adapter such as

public int currentIndex;

@Override
public Fragment getItem(int index) {
    if(position == currentIndex){
        return new EmptyFragment();
    }else{
        return new YourNormalFragment();
    }
}

and becareful to modify

    yourViewPager.setCurrentItem(index);

along with

    yourAdapter.currentIndex = index;
