Hi,
Chronometer as stopwatch is code as below. But it seems some how
elapsedTime is 1 sec or so at times counted more than the reading on
chronometer. I have tried to set the startTime, base time etc. to
favor calculating the correctly but no good. any one can spot the
error.
logic: allow start, stop, start, stop to compute total time.
on start I sync the base to elapsedRealtime so that when stopped I can
capture the time elapsed for the run. On stop I allow to aggregate
the value and display it. Reset code not shown clears the display
string and resets the total elapsed time.
Button btn=(Button)findViewById(R.id.startTimer);
btn.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
chrono.setBase(SystemClock.elapsedRealtime());
chrono.start();
startTime = SystemClock.elapsedRealtime();
}
});
btn=(Button)findViewById(R.id.stopTimer);
btn.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
long elapsedTime = SystemClock.elapsedRealtime() -
chrono.getBase();
chrono.stop();
totalElapsedTime += elapsedTime;
long minutes = (totalElapsedTime / 1000 ) / 60;
long seconds = (totalElapsedTime / 1000 ) % 60;
displayTotalTime = "" + minutes + ":" + seconds;
updateLabel();
}
});
