Updated items on recyclerView are lost when view pager is used

Question

When i change recyclerView data of one tab,data is being reflected(working fine), but when i switch to other tabs and go back to updated tab , the updated items on recyclerView are lost .how to notify viewpager adapter that i have changed data in recyclerAdapter.

Answer 1

Actually, ViewPager loads the next and previous (if any) fragment on initialization and if you will go to the second tab it will load 3rd automatically. You need to use:

viewpager.setOffscreenPageLimit(3);//3 is the limit not refreshing the fragment till 2 swipes

Hope this will solve your problem.
