Implement timer countdown

Question

The problem is this: the countdown in my TextView starts from the 4th second and on the 1st, 0 — it is not shown, although the timer is idle, as if it counts to zero. How can I get a count from 5 to 1. Can you advise other implementations of the countdown timer?

 timer = new CountDownTimer(5000, 1000) { public void onTick(long millisUntilFinished) { // присваиваю значение TextView timerText.setText("00:0" + millisUntilFinished / 1000); } public void onFinish() {} }.start();

Hurried with a question. I solved the problem like this: At the input of CountDownTimer two variables:

 new CountDownTimer(long millisInFuture, long countDownInterval) {...}

I changed the long countDownInterval from 1000 to 1 and everything works, it counts from 4 to 0.

not the best solution, you call onTick every ms, it can load the stream.

The easiest way here is to slightly increase the time of the timer so that the View has time to display the element.

 timer = new CountDownTimer(5100, 1000) { public void onTick(long millisUntilFinished) { // присваиваю значение TextView timerText.setText("00:0" + millisUntilFinished / 1000); } public void onFinish() {} }.start();

The countdown will be from 5 to 1 (visually) at the end there will be a slight delay of 100ms, and the onFinish () call.

Yes, I initially did this, but the timer behaves incomprehensibly, then it starts counting from 4 then from 5.
It should not be, put the time 5999 then 100% will be 5-4-3-2-1 but at the end there will be a delay of 999ms.
By the way, you have "00: 0" + millisUntilFinished / 1000 at 10 + s and will no longer be beautiful

 timer = new CountDownTimer(5000, 1000) { public void onTick(long millisUntilFinished) { // присваиваю значение TextView timerText.setText("00:0" + millisUntilFinished / 1000); if (millisUntilFinished == 1000) { timer.cancel(); } } public void onFinish() {} }.start();
