Question

I want to build an android application, this application allow the users to answer some questions.
For every question, User have to answer it in 360 seconds, so I want to make a digital clock starts from 360secons and then down to 0 seconds

I read that I can’t set time on digital clock , is it so?

or I have to use Chronometer?

this is my digital clock

DigitalClock timer;
public void init(){
timer=(DigitalClock)findViewById(R.id.dcTimer);
}

any help appreciated.

Answer 1

Use CountDownTimer instead.

That link also shows you how to update a TextView every 1 second.

Just change new CountDownTimer(30000, 1000) so the first parameter is 360000 instead of 30000 and that will give you a good start to your code.

EDIT : You need to import android.os.CountDownTimer and the code example I referred to is below. Good luck.

new CountDownTimer(30000, 1000) {

    public void onTick(long millisUntilFinished) {
        mTextField.setText("seconds remaining: " + millisUntilFinished / 1000);
    }

    public void onFinish() {
        mTextField.setText("done!");
    }
}.start();
