How to know if a dialog is dismissed in Android?

You can use an onDismissListener

http://developer.android.com/reference/android/content/DialogInterface.OnDismissListener.html

public Dialog createDialog() {    Dialog d = new Dialog(this);    d.setOnDismissListener(new OnDismissListener() {        @Override        public void onDismiss(final DialogInterface arg0) {            // do something        }    });    return d;}

If you are using a DialogFragment just override onDismiss()

http://developer.android.com/reference/android/app/DialogFragment.html#onDismiss(android.content.DialogInterface)

@Ken Wolf has a great answer to this question.

Just wanted to add that onDismissListener was only introduced in API 17. If you are trying to support something lower, you can use onCancelListener, which is not as good but covers cases like backButton and tapping outside of the AlertDialog.

http://developer.android.com/reference/android/content/DialogInterface.OnCancelListener.html#onCancel(android.content.DialogInterface)

public Dialog createDialog() {    Dialog d = new Dialog(this);    d.setOnCancelListener(new DialogInterface.OnCancelListener() {        @Override        public void onCancel(DialogInterface dialog) {            // do something        }    });}

I noticed that the onDismissListener is called even when you select one of the options in the alert (Yes/No/Neutral button). For me onCancelListener was the best option since I needed something that tracked an explicit closing of the dialog by clicking outside the alert area.
