Hello, I would like to know if you can set the initial value of a chonometer based on a textView.
texView that would like to set the start of the highlighted blue chronometer.
This textView receives data from a server, but it is not real-time, updating only on OnResume.
The value that is in the TextView is a string that represents minutes and seconds. To use it as the start value of the Chonometer, you have to convert it to milliseconds.
Create a method for conversion:
private long minutesAndSecondsToMilliseconds(String minutesAndSeconds){
String[] timeParts = minutesAndSeconds.split(":");
int minutes = Integer.parseInt(timeParts[0]);
int seconds = Integer.parseInt(timeParts[1]);
return (minutes * 60 + seconds) * 1000;
}
Note: The method assumes that the value in the string minutesAndSeconds is in the mm:ss format. mm can be greater than 59.
Use it like this:
TextView textView = (TextView)findViewById(R.id.textView);
Chronometer chronometer = (Chronometer)findViewById(R.id.chronometer);
...
...
long milliseconds = minutesAndSecondsToMilliseconds(textView.getText().toString());
chronometer.setBase(SystemClock.elapsedRealtime() - milliseconds);
