Answer 1

You can check this using boolean variable.when you start chronometer you set boolean variable true and when it stop you set boolean variable false.

boolean isChronometerRunning = false;
if (true)  // condition on which you check whether it's start or stop
{
    chronometer.start();
    isChronometerRunning  = true;
}
else
{
  chronometer.stop();
  isChronometerRunning  = false;
}
