android chronometer start from last stop

Question

Although there are answered questions about this, none REALLY answers the following: I want the android chronometer to start from the last stop, NOT to continue counting time. I try the following, but IT DOES NOT WORK :-(

public class MainActivity extends ActionBarActivity {
  long stopTime = 0;

  public void startChronometer(View view) {
    long elapsedTime = SystemClock.elapsedRealtime() - stopTime;
    ((Chronometer) findViewById(R.id.mycrono)).setBase(elapsedTime);
    ((Chronometer) findViewById(R.id.mycrono)).start();
  }
  public void stopChronometer(View view) {
    stopTime = findViewById(R.id.mycrono).getBaseline();
    ((Chronometer) findViewById(R.id.mycrono)).stop();
  }

  ............. // standard android methods

results crazy numbers...

0*60000=0.. so what do you mean by this?? – George Violettas Apr 26 '15 at 06:53
actually 0*6000 means if you want to use last time in mints instead of second than you can use like this l3*6000 – vishal jangid Apr 28 '15 at 04:53

This is works for me. I have 3 buttons (Start, pause, stop).

    private var stopTime : Long = 0


    /*Put this in your method, where you want to handle the buttons. 
      I worked with FloatingActionsButtons*/

    fab_start.setOnClickListener {
            chronometer.base = SystemClock.elapsedRealtime() + stopTime
            chronometer.start()
        }
    fab_pause.setOnClickListener {
            stopTime = chronometer.base - SystemClock.elapsedRealtime()
            chronometer.stop()
        }
    fab_stop.setOnClickListener {
            chronometer.base = SystemClock.elapsedRealtime()
            stopTime = 0
            chronometer.stop()
        }
