Android Chronometer实现时分秒的显示

int miss = 0;
chronometer.start();
chronometer.setOnChronometerTickListener(new OnChronometerTickListener() {
 
                    @Override
                    public void onChronometerTick(Chronometer ch) {
                        miss++;
                        ch.setText(FormatMiss(miss));
 
                    }
                });
 
// 将秒转化成小时分钟秒
    public String FormatMiss(int miss){     
        String hh=miss/3600>9?miss/3600+"":"0"+miss/3600;
        String  mm=(miss % 3600)/60>9?(miss % 3600)/60+"":"0"+(miss % 3600)/60;
        String ss=(miss % 3600) % 60>9?(miss % 3600) % 60+"":"0"+(miss % 3600) % 60;
        return hh+":"+mm+":"+ss;      
    }
