android中实现时分秒显示

Chronometer m1=(Chronometer)this.findViewById(R.id.chronometer1);//        m1.setFormat("计时信息：%s");        m1.start();          m1.setOnChronometerTickListener(new OnChronometerTickListener() {           int miss = 0;                                        @Override                              public void onChronometerTick(Chronometer ch) {                                  miss++;                                  ch.setText(FormatMiss(miss));                              }                          });
