推荐答案

你可以使用 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;
}

如果您使用的是 DialogFragment，只需覆盖 onDismiss()

If you are using a DialogFragment just override onDismiss()
