此错误继续弹出:找不到id 0x7f08003d的视图

Question

我创建了一个片段，我想将它插入到我的cardview内容中的framelayout中。在片段中有另一个reyclerView。

View view;
private List<DayViewItem> dayItemList = null;

public static Day_Fragment newInstance() {
    // Required empty public constructor
    Day_Fragment day_fragment = new Day_Fragment();
    return day_fragment;
}


@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {

    // Inflate the layout for this fragment
    view = inflater.inflate(R.layout.fragment_day_, container, false);

    initializeDayItemList();

    //Create recyclerview
    RecyclerView dayRecyclerView = view.findViewById(R.id.day_recycler_list);

    // Create the grid layout manager with 2 columns
    GridLayoutManager gridLayoutManager = new GridLayoutManager(getContext(), 1);

    // Set layout manager.
    dayRecyclerView.setLayoutManager(gridLayoutManager);

    // Create recycler view data adapter with item list.
    DayViewDataAdapter dayDataAdapter = new DayViewDataAdapter(dayItemList);
    // set data adapter
    dayRecyclerView.setAdapter(dayDataAdapter);

    return view;
}

private void initializeDayItemList() {

    if (dayItemList == null)
    {
        dayItemList = new ArrayList<DayViewItem>();

        dayItemList.add(new DayViewItem("Blade Replacement","Normal", "Done"));
        dayItemList.add(new DayViewItem("Blade Replacement","Daily", "Done"));
        dayItemList.add(new DayViewItem("Device Change Setup Checklist","Normal", "Cancel"));
        dayItemList.add(new DayViewItem("Device Change Setup Checklist","Daily", "Cancel"));
    }
}

我将片段插入到MainActivity中

Fragment DayFragment = new Day_Fragment();
    FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
    transaction.setCustomAnimations(android.R.anim.slide_in_left, android.R.anim.slide_out_right)
            .replace(R.id.day_container, ((Day_Fragment) DayFragment).newInstance())
    .commit();

我有这个错误：

java.lang.IllegalArgumentException: No view found for id 0x7f08003d (com.example.nestedrecyclerview:id/day_container) for fragment Day_Fragment{2b9a2b0 #0 id=0x7f08003d}

Answer 1

找不到R.id.day_container，这可能是由于多种原因造成的。例如，根据语言或设备分辨率加载不同的资源，并且在已加载的资源中找不到此id，或者访问不包含此资源的R文件。

您是否可以仔细检查您正在加载的资源是否包含此特定ID？(day_container)

• Could您在R资源上使用完全限定名？(your.package.R.id.day_container)

Answer 2

请使用

@Override
public void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState) {

绑定视图(即findViewById)。

onCreateView()用于扩展布局，但不用于绑定视图(例如，findViewById)
