How do I make a CountDownTimer show at the same moment my Button gets enabled? : "How do I make a CountDownTimer show at the same moment my Button gets enabled ?"

Additional info regarding the button: the Buttons Job is it to click 5 times through a stringarray displayed in a Textview to then get disabled for 5 seconds to do the same task again.

so ..I would like a CountDownTimer to visually show those 5 seconds count down for the User to see.

sadly I dont have an idea how to connect my Button with the CountDownTimer to let it know its supposed to countdown at that particular time the Button is enabled.

Also I would like for the CountDownTimer to show  everytime the Button gets enabled. 

I looked into https://developer.android.com/reference/android/os/CountDownTimer
but it doesnt seem to have a solution for that particular case.

thats my Code for the Button as of now : 
   
    next_button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                if (currentnumber == list.length) {
                    currentnumber = 0;
                }
                if (Curclicks == mod - 1) {
                    next_button.setEnabled(false);
                    display.setText(list[currentnumber]);
                    currentnumber++;


                    handler.postDelayed(new Runnable() {
                        @Override
                        public void run() {
                            //the button will unlock after the delay specified
                            next_button.setEnabled(true);
                            Curclicks = 0;

                        }
                    }, delay);

                } else {
                    display.setText(list[currentnumber]);
                    currentnumber++;

                }
                Curclicks++;

            }

        });

I hope I was clear enough and u have a solution for me, thank you in advance.
