Answer 1

I was dealing with the same issue. The easiest way to achieve this goal would be overriding updateText method of the Chronometer, but unfortunately it is a private method so I have done this in this way :

    mChronometer.setText("00:00:00");
    mChronometer.setOnChronometerTickListener(new Chronometer.OnChronometerTickListener() {

        @Override
        public void onChronometerTick(Chronometer chronometer) {
            CharSequence text = chronometer.getText();
            if (text.length()  == 5) {
                chronometer.setText("00:"+text);
            } else if (text.length() == 7) {
                chronometer.setText("0"+text);
            }
        }
    });

I know that it would be better to write custom widget but for small project it can be suitable.

Setting format on chronometer allows formatting text surrounding actual time and time is formatted using DateUtils.formatElapsedTime .

Hope that helps.

Here is an easy and smart solution for time format 00:00:00 in chronometer in android

Chronometer timeElapsed  = (Chronometer) findViewById(R.id.chronomete);
timeElapsed.setOnChronometerTickListener(new OnChronometerTickListener(){
        @Override
            public void onChronometerTick(Chronometer cArg) {
            long time = SystemClock.elapsedRealtime() - cArg.getBase();
            int h   = (int)(time /3600000);
            int m = (int)(time - h*3600000)/60000;
            int s= (int)(time - h*3600000- m*60000)/1000 ;
            String hh = h < 10 ? "0"+h: h+"";
            String mm = m < 10 ? "0"+m: m+"";
            String ss = s < 10 ? "0"+s: s+"";
            cArg.setText(hh+":"+mm+":"+ss);
        }
    });
    timeElapsed.setBase(SystemClock.elapsedRealtime());
    timeElapsed.start();
