Question

我有一个FragmentActivity，附有3个片段。这3个片段有一个天文台，我希望它们在它们之间共享相同的时间......

我试图同时开始（）他们所有人，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，但它似乎不起作用......

有人能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;
}

FragronActivity onChronometerTick监听器

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

Answer 1

好的，我找到了解决方案！

我没有为所有片段创建计时器，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。

计时器在片段之间共享
