android - Attaching listener to dialog -


i need notified when there changes on screen. using

this.getwindow().getdecorview().getviewtreeobserver().addongloballayoutlistener(new viewtreeobserver.ongloballayoutlistener()         {             @override             public void ongloballayout()             {                 log.d("tag", "global layout");             }         });

but doesn't work when dialog(custom, alert, progress, etc.) shown or dismissed. understand dialogs shown on overlay listener isn't attached them. how can desired functionality?

you need dialog.setondismisslistener or dialog.setoncancellistener

they'll called when related dialog dismissal happens or being canceled.
