我正在尝试通过点击通知在我的导航图中打开一个特定的目的地。我按如下方式创建了 Pending Intent-
//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，这是同一个片段，设置为目标R.id.occasionViewer，但我正在导航到导航的开始目标片段图是“dashboardFragment”。
我尝试将目的地更改为同一图表中的其他目的地之一 R.id.addBirthdayFragment，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，意味着在点击通知时我正在导航到 addBirthdayFragment。
能否请你调查一下，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。

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)，我使用 Occasion 来更新不同的值。
我在 onActivityCreated() 中使用观察者。

我的 DashboardFragment 有一个回收视图，在项目上单击它导航到 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，它出现了这个错误：

我是这样调用startPostponedEnterTransition();的
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();
