Android: FragmentPagerAdapter: getItem method called twice on First time

Question

In My application, I have used the ViewPager. Like,

(say main.xml)



        

Answer 1

The FragmentPagerAdapter instantiates 2 Fragments on start, for index 0 and for index 1. If you want to get data from the Fragment which is on the screen, you can use setOnPageChangeListener for the Pager to get current position. Then have SparseArray with WeakReference to your fragments. Update that array in the getItem call. When onPageSelected gets called use that position to get reference to right Fragment and update User data.

Initialization of array:

private SparseArray> mFragments = new SparseArray>(3);
