android - Kill audio after deliberate or accidental exit of dialog -

this part of code in mainactivity. stopwatch1 image button called in mainactivity:

           stopwatch1 = (imagebutton)findviewbyid(r.id.stopwatch1); 

i have tried searching clues on how use dialog.setondismisslistener, however, there aren't proper answers me killing of audio after deliberate or accidental exit of dialog. appreciated.

           stopwatch1.setonclicklistener(new view.onclicklistener() {                      @override                     public void onclick(view v) {                         final dialog mmdialog1 = new dialog(context);                         mmdialog1.setcontentview(r.layout.countdowntimer);                         mmdialog1.settitle("stop-watch");                                     button ddbutton1 = (button) mmdialog1.findviewbyid(r.id.countdown_exit);                         final button ddbutton2 = (button) mmdialog1.findviewbyid(r.id.countdown_start);                         final textview timeview = (textview) mmdialog1.findviewbyid(r.id.timeview);                         ddbutton2.settag(1);                          ddbutton2.setonclicklistener(new onclicklistener() {                             @override                             public void onclick(view v) {                                 final int status = (integer) v.gettag();                                  if (status == 1) {                                     ddbutton2.settext("stop");                                     countdowntimer = new countdowntimer(60000, 1000) {                                          public void ontick(long millisuntilfinished) {                                             int time = (int) (millisuntilfinished/1000);                                             timeview.settext(integer.tostring(time));                                         }                                         @override                                         public void onfinish() {                                             timeview.settext("60");                                             ddbutton2.settext("start");                                             mediaplayer stop = mediaplayer.create(context, r.raw.stop);                                             stop.start();                                         }                                     }.start();                                     v.settag(0);                                  } else {                                     ddbutton2.settext("start");                                     timeview.settext("60");                                     countdowntimer.cancel();                                     v.settag(1);                                 }                             }                          });                          ddbutton1.setonclicklistener(new onclicklistener() {                             @override                             public void onclick(view v) {                                 mmdialog1.dismiss();                             }                         });                          mmdialog1.show();                     }                 }); 

my suggestion implement interface. when dialog closes, have callback shut off media player.

a quick example this.

interface

public interface dialogclosed {     void shutdownmediaplayer(); } 

then implement interface in calling activity

activity

public class mainactivity extends activity implements dialogclosed {     ....     @override     public void shutdownmediaplayer() {         //shut down media player here     } } 

also, may add boolean check if dialog showing this

boolean isshowing = mdialog.isshowing(); 

and can shut off media player @ point if false.
