我有这个奇怪的问题,我的适配器没有调用任何方法..构造函数工作,它停在那里,如果我有一个断点,但从那里,没有.. onCreateViewHolder没有被调用,既没有onBindViewHolder,甚至没有getItemCount ..我尝试了我在网上找到的所有东西,但似乎没有任何工作,所以我不知道该怎么做.有什么建议？这是我的代码：
分段：

public class FragmentPackageDetails extends Fragment {
    //other vars
    RecyclerView rvPackageDetails;
    DatabaseHandler database;

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater,ViewGroup container,Bundle savedInstanceState) {
        Bundle args = getArguments();
        String temp = args.getString(KEY_TRACKER_CODE);
        View v = inflater.inflate(R.layout.fragment_package_details_new,container,false);

        return v;
    }

    @Override
    public void onViewCreated(View view,@Nullable Bundle savedInstanceState) {
        super.onViewCreated(view,savedInstanceState);
        rvPackageDetails = (RecyclerView) view.findViewById(R.id.rvPackageDetails);
        rvPackageDetails.setLayoutManager(new LinearLayoutManager(getActivity()));

        database = new DatabaseHandler(getActivity());
        selectedPackage = database.getPackage(trackerCode);

        RecyclerView.Adapter adapter = new MyAdapter(selectedPackage.getRecords());
        rvPackageDetails.setAdapter(adapter);
    }
    //other methods in class
}
