问题 I have a viewpager with 5 tabs and if I go to the 5th fragment(that is the fragment loaded when I click the 5th tab or swipe to the 5th tab) and then I go to the 3rd tab the 5th fragment won't load the view anymore and if I go to the 2nd or 1st tab the 4th and 5th tabs won't. I tried changing the viewpager.offscreenlimit(3) or even 5 with no results. If it helps anyone figure it out, it happens regardless of what fragments I put in place of the 3rd 4th and 5th positions. Also, the first
