How do I fire an event when click occurs outside a dialog

Question

I would like to know how to solve a problem I've got.

I have a Dialog which pops up in an activity. The Dialog doesn't cover the whole screen, so the buttons from the activity still show. I can easily close the dialog when there is a touch outside the dialog's bounds with dialog.setCanceledOnTouchOutside(true);

However what I want to do is fire an event if a click is outside the Dialog's bounds (e.g if someone touches a button on the main Activity, it should close the Dialog and fire that event at the same time).

Answer 1

When dialog.setCanceledOnTouchOutside(true); then you just override onCancel() like this:

dialog.setOnCancelListener(
        new DialogInterface.OnCancelListener() {
            @Override
            public void onCancel(DialogInterface dialog) {
                //When you touch outside of dialog bounds, 
                //the dialog gets canceled and this method executes.
            }
        }
);

Type your code inside the onCancel() method so it runs when the dialog gets canceled.
