intercept DialogFragment dismiss inside activity

I have an activity 

public class ShowFileActivity extends FragmentActivity

and when occours some event, this class call a DialogFragment

public class ConfirmDialog extends DialogFragment

that is a simple confirm dialog (with "dismiss" and "ok" button). If user press dismiss button, i call

dismiss()

and come back to ShowFileActivity. Else, if user press ok, after made some operations, after call dismiss on dialog, i would go back to parent activity of ShowFileActivity. There's a way to do it? Does DialogFragment launch any event to his parent view?

What you can do is to call a method of the containing activity from inside the fragment. As per any other fragment, you can call getActivity() which returns the containing activity.

@Override
public void onDismiss(DialogInterface dialog) {
    ShowFileActivity parent = (ShowFileActivity) getActivity();
    parent.doWhateverYouWantWhenDialogDismissed();
}

Another (more fancy) approach would be to use an event bus such as otto or greenrobot.
