Dismiss AlertDialog from within it's button's callback

I want to be able to dynamically dismiss an AlertDialog from within it's own button callback:

    final AlertDialog.Builder alert = new AlertDialog.Builder(this);
    alert.setNeutralButton(R.string.enter, new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int whichButton) {
            if (/* if some condition is met */) {
                // dismiss the alert
            } else {
                // keep the alert open
            }
        }
    });
    final AlertDialog alert_dialog = alert.create();
    alert_dialog.getWindow().setType(WindowManager.LayoutParams.TYPE_TOAST);
    alert_dialog.setCanceledOnTouchOutside(false);
    alert_dialog.show();

I know that I can call dismiss() on alert_dialog but I cannot put this call within the very code that creates it.

The DialogInterface in the callback is the Dialog itself (Dialog implements DialogInterface), so all you have to do is call the DialogInterface#dismiss() method:

alert.setNeutralButton(R.string.enter, new DialogInterface.OnClickListener() {
    public void onClick(DialogInterface dialog, int whichButton) {
        if (/* if some condition is met */) {
            dialog.dismiss(); // dismiss the alert
        } else {
            // keep the alert open
        }
    }
});
