RecyclerView throwing java.lang.IllegalStateException: 指定的 child 已经有一个 parent

Question

我的 RecyclerView 在 Coordinator 布局中的片段内膨胀时抛出上述错误。与 parent 布局有任何联系吗？我已经查看了与此错误相关的所有答案，但 none 可以解决我的问题。这是片段+适配器的代码

public static class EditJob extends Fragment {

    ServerRequests serverRequests;
    UserLocalStore userLocalStore;
    User receivedUser;
    EditText searchJob;
    ImageView searchBtn;
    RecyclerView editJobRecycler;
    MyRecyclerAdapter editJobAdapter;
    ArrayList<Job> arrayJob;
    TextView noJobSearch;

    @Override
    public void onAttach(Context context) {
        super.onAttach(context);
        serverRequests = new ServerRequests(context);
        userLocalStore = new UserLocalStore(context);
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_edit_job, container, false);
        receivedUser = userLocalStore.getAllDetails();
        arrayJob = new ArrayList<>();
        noJobSearch = (TextView) view.findViewById(R.id.noJobEdit);
        searchJob = (EditText) view.findViewById(R.id.etEditJob);
        searchBtn = (ImageView) view.findViewById(R.id.editJobImage);
        editJobRecycler = (RecyclerView) view.findViewById(R.id.jobEditRecycler);
        editJobAdapter = new MyRecyclerAdapter(arrayJob);
        editJobRecycler.setLayoutManager(new LinearLayoutManager(getContext()));
        editJobRecycler.setAdapter(editJobAdapter);
        searchBtn.setOnClickListener(new View.OnClickListener() {
            @Override

    }

    public void searchJob() {
        arrayJob.clear();
        serverRequests.searchJobListings(searchJob.getText().toString(), new GetJobObjectsCallBack() {

                    noJobSearch.setVisibility(View.GONE);
                    for (int i = 0; i < returnedJobs.length; i++) {
                        arrayJob.add(i, returnedJobs[i]);
                    }
                    editJobAdapter.notifyDataSetChanged();

我已经尝试了所有方法，包括 parent.removeAllViews() 但似乎没有任何效果。我也用几乎相同的代码实现了其他 RecyclerViews，但它们都工作得很好。任何帮助将不胜感激。

尝试将其更改为...

View v = li.inflate(R.layout.job_item_list, parent,false);
