点击通知以使用导航组件打开应用程序目的地，目的地不正确

Question

我正在尝试通过点击通知在导航图中打开特定目的地。我创建了 Pending Intent 如下-

//this code in service to create notification       
OccasionViewerArgs.Builder builderArg = new OccasionViewerArgs.Builder();
builderArg.setPrimaryKey(2);
builderArg.setOccasionClickType("Birthday");
PendingIntent pendingIntent = new NavDeepLinkBuilder(this)
    .setGraph(R.navigation.dashboard_navigation)
    .setDestination(R.id.occasionViewer)
    .setArguments(builderArg.build().toBundle())
    .createPendingIntent();

问题：

当我点击通知时，我希望导航到我的“occasionViewer”片段，这是相同的片段，设置为目的地R.id.occasionViewer，但我正在导航到导航图的开始目的地片段，即“仪表板片段”。

我尝试将目的地更改为同一图中 R.id.addBirthdayFragment 中的其他目的地之一，如下所示 -

PendingIntent pendingIntent = new NavDeepLinkBuilder(this)
    .setGraph(R.navigation.dashboard_navigation)
    .setDestination(R.id.addBirthdayFragment)
    //.setArguments(builderArg.build().toBundle())
    .createPendingIntent();

然后它按预期工作，意味着在通知点击时我正在导航到 addBirthdayFragment。

您能否调查一下，让我知道我在这里做错了什么，任何建议或帮助都会让我开心。

这里是 nav_graph (R.navigation.dashboard_navigation)

观察者如下

private LiveData<Occasion> occasionLiveData;

        occasionLiveData = AppRoomDatabase.getDatabase(requireContext().getApplicationContext())
                .occasionDao().findOccasionByKey(primaryKey);

        occasionLiveData.observe(getViewLifecycleOwner(), new Observer<Occasion>() {
            @Override
            public void onChanged(Occasion occasion) {
                if (occasion != null) {
                    setupValues(occasion);
                }
            }
        });

方法setupValues(occasion)，在这里我使用Occasion 来更新不同的值。

我在 onActivityCreated() 中使用观察者。

编辑 3（一些观察）

我的 DashboardFragment 有一个回收视图，在项目单击时导航到 OccasionViewer，但是当点击通知时，它确实将我带到 DashboardFragment，然后我单击回收视图项目，它会出现此错误：

我打电话给startPostponedEnterTransition();如下

private void setupValues(Occasion occasion) {
    matchingOccasion = occasion;
    collapsingToolbarLayout.setTitle(matchingOccasion.getPersonName());
    String personImageID = matchingOccasion.getPersonImage();
    if (!personImageID.isEmpty()) {

    File filepath = requireContext().getExternalFilesDir(null);
    File file = new File(filepath + "/" + personImageID + ".jpeg");
    Picasso.with(requireContext()).load(file)
        .into(personImg, new Callback() {
    @Override
    public void onSuccess() {
        // startPostponedEnterTransition();
    }
    .......

问题已通过以下更改解决 -

public void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);
    ......
    startPostponedEnterTransition();
    ......

再次感谢 AdrianK 花时间研究我的代码。干杯.. !!
