“ int android.view.View.getImportantForAccessibility（）”是什么意思，以及如何解决？

Question

我在一个空对象引用上显示“ int android.view.View.getImportantForAccessibility（）”错误。我创建了自己的代码，并收到此错误。该如何解决？

这是我的代码：

        databaseHelperCompetenciesDate = new DatabaseHelperCompetenciesDate(getActivity());

        studentDateArrayList = new ArrayList<>();
        studentDateArrayList = databaseHelperCompetenciesDate.getStudentDate();
        final CompetenciesDateStudentAdapter competenciesDateStudentAdapter = new CompetenciesDateStudentAdapter(getActivity(), studentDateArrayList);
        lv = rootView.findViewById(R.id.recommendations_list);
        lv.setAdapter(competenciesDateStudentAdapter);

        lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
                competenciesStudentDate = (CompetenciesStudentDate) competenciesDateStudentAdapter.getItem(i);
                LearningRecommendations learningRecommendations = new LearningRecommendations();
                Bundle bundle = new Bundle();
                bundle.putString("id", competenciesStudentDate.getID());
                bundle.putString("studentName", competenciesStudentDate.getStudentName());
                bundle.putString("recommendedModules", competenciesStudentDate.getRecommendedModules());
                bundle.putString("comments", competenciesStudentDate.getComments());
                bundle.putString("date", competenciesStudentDate.getDateAdded());
                learningRecommendations.setArguments(bundle);
                FragmentManager manager =  getFragmentManager();
                manager.beginTransaction().replace(R.id.fragment_container, learningRecommendations).commit();
            }
        });

        return rootView;
