Prevent ViewPager from destroying off-screen views

Question

I have a ViewPager hooked up to a FragmentPagerAdapter that\'s displaying three fragments. The ViewPager appears to destroy a hosted fragment\'s view when it is more than on

Answer 1

By default, ViewPager recreates the fragments when you swipe the page. To prevent this, you can try one of two things:

1. In the onCreate() of your fragments, call setRetainInstance(true).

2. If the number of fragments is fixed & relatively small, then in your onCreate() add the following code:

ViewPager mViewPager = (ViewPager) findViewById(R.id.pager);
mViewPager.setOffscreenPageLimit(3);

If I remember correctly, the second option is more promising. But I urge you to try both and see which of them work.
