碎片之间的计时表份额

我有一个附加了3个碎片的碎片活动。这3个片段有一个计时表,我希望它们之间共享相同的时间。。。

• 我试着同时开始他们,但有时他们突然从00.00开始。。。
• 我试图通过onChronometerTick()将时间存储在FragmentActivity上,但似乎不起作用。。。

有人能告诉我怎么做我想做的吗?

片段1

public class Run1Fragment extends Fragment {
private Chronometer chronometer;
private WearRunActivity runActivity;
private Run2Fragment run2;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.layout_run1, container, false);
    chronometer = (Chronometer) view.findViewById(R.id.chronometer);
    runActivity = new WearRunActivity();
    chronometer.setOnChronometerTickListener(runActivity);
    chronometer.start();

    return view;
}

片段2

public class Run2Fragment extends Fragment {
private Chronometer r2Chronometer;
Run1Fragment run1;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.layout_run2, container, false);
    r2Chronometer = (Chronometer) view.findViewById(R.id.chronometer);

    /*r2Chronometer.setBase(run1.getChronometer().getBase());
    r2Chronometer.start();*/

    return view;
}

计时计时器上的碎片活动Tick侦听器

@Override
public void onChronometerTick(Chronometer chronometer) {
    System.out.println("CRONOMETROOOO");
    this.chronometer.setBase(chronometer.getBase());
}
