碎片之间的计时器共享

Question

我有一个包含 3 个片段的 FragmentActivity attached.This 3 个片段有一个计时器，我希望它们共享相同的时间...

我尝试同时启动（）它们，但有时它们突然从 00.00 开始...
我尝试通过 onChronometerTick() 将时间存储在 FragmentActivity 上，但它似乎不起作用...

有人可以告诉我如何做我想做的事吗？

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;
}

FragmentActivity onChronometerTick 侦听器

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

Answer 1

好的，我找到了解决办法！

我没有为所有片段创建计时表，而是将其集成到片段活动片段中，因此只有我想要更改的文本才会被放置在其他片段中。
