Android ListView doesn't (re) populate on "back" -
i have simple android app - dictionary. using listview populate dictionary words on main glossary screen. if word touched new intent launches wordscreen shows word , definition. problem if hit "back" go wordscreen glossary listview not populate.
i using onstop() close database cursor when moving glossary screen, , onrestart() open cursor , (i thought) populate listview. doesn't seem working.
one important thing, if after going glossary screen word screen (and getting black screen no listview) change orientation of app listview populates.
i thought pressing "back" cause onrestart() execute. why pressing not cause listview populate, changing orientation does?
thanks
use onpause , onresume instead. changing orientation causes activity destroyed , restarted, navigating activity causes activity paused. when click it's resumed.
