Начало фрагмента из адаптера RecyclerView

Question

Я начинаю новый Fragment с моего адаптера RecyclerView. Это код.

@Override 
public AdapterDrawer.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { 

    if(viewType == ITEM) { 
     view = LayoutInflater.from(parent.getContext()).inflate(R.layout.row_item_drawer, parent, false); 
     viewHolder = new ViewHolder(view, viewType); 

     return viewHolder; 

    } else if (viewType == HEADER) { 
     view = LayoutInflater.from(parent.getContext()).inflate(R.layout.header, parent, false); 
     viewHolder = new ViewHolder(view, viewType); 

     return viewHolder;  
    } 

    return null; 
} 

public ViewHolder(View view, int viewType) {    
    super(view); 

    switch(viewType) { 
    case ITEM: 
     // ..... code 

     break; 
    case HEADER: 
     //code.... findiewById ecc 

     mycardView.setOnClickListener(new OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       // TODO Auto-generated method stub 
       Bundle bundle = new Bundle(); 
       bundle.putString("Code", "Value"); 
       Fragment fragment = new MyFragment(); 
       fragment.setArguments(bundle); 
       ((ActionBarActivity)context).getFragmentManager().beginTransaction().replace(R.id.container, fragment).commit(); 
      }     
     }); 

     break; 

Когда я нажимаю на CardView я получил эту ошибку

Почему? Как я могу решить? Мой RecyclerView находится внутри Fragment.

Попробуйте заменить следующие строки

view = LayoutInflater.from(parent.getContext()).inflate(R.layout.row_item_drawer, parent, false); 
view = LayoutInflater.from(parent.getContext()).inflate(R.layout.header, parent, false); 

с

view = LayoutInflater.from(parent.getContext()).inflate(R.layout.row_item_drawer, null); 
view = LayoutInflater.from(parent.getContext()).inflate(R.layout.header,null);
