Android recyclerview в статье recyclerview

Question

Я создаю приложение для школьного проекта, я хочу, чтобы сделать недельный планировщик для студентов в моем приложении. Для этого мне нужно добавить recyclerview в элемент recyclerview, но когда я запускаю свое приложение, он ничего не показывает. Я думаю, что это ошибка в

LogCat: 06-19 15:43:36.926 2980-2980/com.sapps.tools.dedykapp E/RecyclerView﹕ No adapter attached; skipping layout. Вот мой код:

PlannerActivity.java

//day planner monday 
    ArrayList<DayItems> mon = new ArrayList<>(); 
    mon.add(new DayItems("huiswerk maken")); 

    LinearLayout v = (LinearLayout)getLayoutInflater().inflate(R.layout.dayitems, viewGroup); 

    RecyclerView dayPlan = (RecyclerView)v.findViewById(R.id.mon); 
    dayPlan.setHasFixedSize(true); 
    LinearLayoutManager linearLayoutManager = new LinearLayoutManager(this); 
    linearLayoutManager.setOrientation(LinearLayoutManager.VERTICAL); 
    dayPlan.setLayoutManager(linearLayoutManager); 

    DayRecAdapter dayAdapter = new DayRecAdapter(mon); 
    dayPlan.setAdapter(dayAdapter); 

    //planner 
    RecyclerView plan = (RecyclerView)findViewById(R.id.planner); 
    plan.setHasFixedSize(true); 
    LinearLayoutManager linManager = new LinearLayoutManager(this); 
    linManager.setOrientation(LinearLayoutManager.VERTICAL); 
    plan.setLayoutManager(linManager); 

    PlannerRecAdapter recAdapter = new PlannerRecAdapter(R.layout.dayitems); 
    plan.setAdapter(recAdapter); 

Оба адаптеров для моей программы:

адаптера списка задач, которые находится в пункте рециклинга:

public class DayRecAdapter extends RecyclerView.Adapter<DayViewHolder> { 

ArrayList<DayItems> mList; 

public DayRecAdapter(ArrayList<DayItems> mList){ 
    this.mList = mList; 
} 

public int getItemCount(){ 
    return mList.size(); 
} 

public DayViewHolder onCreateViewHolder(ViewGroup viewGroup, int position){ 
    View v = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.planitem, viewGroup, false); 
    DayViewHolder DVH = new DayViewHolder(v); 
    return DVH; 
} 

public void onBindViewHolder(DayViewHolder vHolder, int i){ 
    vHolder.dayText.setText(mList.get(i).todo); 
} 

} 

Адаптер главный recyclerview:

public class PlannerRecAdapter extends RecyclerView.Adapter<PlannerViewHolder> { 

int layoutResource; 

public PlannerRecAdapter(int layoutResource){ 
    this.layoutResource = layoutResource; 
} 

public int getItemCount(){ 
    return 1; 
} 

public PlannerViewHolder onCreateViewHolder(ViewGroup viewGroup, int position){ 
    View v = LayoutInflater.from(viewGroup.getContext()).inflate(layoutResource, viewGroup, false); 
    PlannerViewHolder PVH = new PlannerViewHolder(v); 
    return PVH; 
} 

public void onBindViewHolder(PlannerViewHolder holder, int i){ 

} 
} 

А вот раскладка ресурс PlannerRecAdapter:

    xmlns:android="http://schemas.android.com/apk/res/android"

Заранее спасибо!

Answer 1

Попробуйте это.

В вашем PlannerActivity.java Объявить

private RecyclerView.Adapter adapter 

Затем в OnCreate метод, найти его, как это.

adapter = new DayRecAdapter(mon); 

Надеется, что это не решит нет адаптера прилагается вопрос

Answer 2

Как говорит предупреждение, вам необходимо установить адаптер prior для установки LayoutManager.

recyclerView.setAdapter(rvAdapter); 
recyclerView.setLayoutManager(lManager); 

Я не уверен, что вы можете установить свой внутренний адаптер таким образом. Я установил его в конструкторе внешнего ViewColder RecyclerView.
