“未连接适配器；跳过片段上的布局”

Question

public class WorkFragment extends Fragment {

List<CardViewItem> items = new ArrayList<>();

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Log.d("FRAGMENT", "Work Fragment started");

    TypedArray icons = getResources().obtainTypedArray(R.array.project_icons);
    TypedArray names = getResources().obtainTypedArray(R.array.project_names);
    TypedArray descs = getResources().obtainTypedArray(R.array.project_descs);
    for (int i=0;i<icons.length();i++){
        items.add(new CardViewItem(icons.getDrawable(i),
                names.getString(i),
                descs.getString(i)));
    }
    icons.recycle();
    names.recycle();
    descs.recycle();
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    Log.d("FRAGMENT", "Work Fragment onCreateView");
    View rootView = inflater.inflate(R.layout.fragment_work, container, false);
    RecyclerView recyclerView = (RecyclerView) rootView.findViewById(R.id.recycler_view);
    LinearLayoutManager llm = new LinearLayoutManager(getActivity(), LinearLayoutManager.VERTICAL, false);
    recyclerView.setLayoutManager(llm);
    recyclerView.setAdapter(new ItemAdapter(items));
    return inflater.inflate(R.layout.fragment_work, container, false);
}
}

给我的

E/RecyclerView: No adapter attached; skipping layout

我已经尝试了我找到的所有解决方案（设置一个空适配器，将代码移动到哪里，使用单独的线程），但无济于事。这应该适用于正常的活动，所以我想也许我做错了什么。

Answer 1

问题主要是这条线

return inflater.inflate(R.layout.fragment_work, container, false);

你应该有

< code >返回rootView

随着第一次返回，您正在膨胀一个新的完全不同的视图层次结构，从fragment_work.xml开始，从正确设置回收器视图的视图层次结构开始。
