android - Go to previous fragment that contains a viewpager -


i have fragment viewpager. each fragment of viewpager can go fragment. problem when go fragment of viewpager not fragment went second fragment. can go same page same fragment when go back?

thanks in advance.

viewpager creates specific amount of pages ahead - choose when use setoffscreenpagelimit(amount). example if set amount 2 @ page in viewpager you'll have 2 pages created ahead , 2 created backwards.

so when you're on 1st page - pages 2 & 3 created. when you're on page 5 you'll have 3 & 4 created , 6 & 7 created. others destroyed (in case of page 5: 1,2 destroyed).

so sounds have 2 options: 1. if know amount of fragments you'll have in view pager, set amount pages exist time. don't idea because it's pretty wasteful. 2. use horizontalscrollview instead of viewpager.
