Android Timer Circular Progress Bar countdown timer does not match timer

Question

Hi, can someone help me in my small project, please, I am following this tutorial and I got to the part where I insert 1 minute into EditText. The progress bar works fine 1 Progress per second, but when I add more than 1 minute to the EditText the Progress indicator does not work. This is not coming, please help?

main.xml

Normal timer status

At the entrance in 1 minute

When I entered 3 minutes

Progress bar not counting

Answer 1

In your main.xml for ProgressBar you specified the maximum value as 60. Thus, the progress bar takes the maximum value as 60, and your progress bar starts to decrease from 60 seconds onwards.

Instead of working correctly with the Progress line, in your setTimer () method, write the following line.

 mProgressBar.setMax(60*time);
