android - Fragment's onDestroyView not called on back button press -

-

i have 3 fragments in application: fragment a, b , c.

steps:

  1. i replacing b , keeping in backstack.
  2. i replacing b c , not keeping b in backstack.
  3. i pressing button, on pressing button a's oncreateview , onstart called (as on stack)

the problem fragment c's onstop, ondestroyview etc not called , fragment not visible on screen , fragment c visible (as it;s view not destroyed).

i believe there misunderstanding of stack. when replace b, put transaction a->b in stack, not fragment. stack knows when user presses button, have rollback transaction: destroy b , recreate a. in case, replacing c b , you're pressing button: recreated , b cannot destroyed since doesn't exist. maybe can find solution listening stack events using fragmentmanager.addonbackstackchangedlistener(), don't know if fits requirement.
