Recyclerview onCreateViewHolder

फोन नहीं मेरे RecyclerView फोन नहीं करता है onCreateViewHolder, onBindViewHolder भी MenuViewHolder निर्माता है, इसलिए कुछ भी नहीं RecyclerView में दिखाई देता है। मैंने डीबगिंग के लिए लॉग डाला, और कोई लॉग दिखाया नहीं गया है। समस्या क्या हो सकती है?Recyclerview onCreateViewHolder

मेरे अनुकूलक:

public class MenuAdapter extends RecyclerView.Adapter<MenuAdapter.MenuViewHolder> { 
private LayoutInflater inflater; 
List<Menu> data = Collections.emptyList(); 

public MenuAdapter(Context context, List<Menu> data) { 
    Log.i("DEBUG", "Constructor"); 
    inflater = LayoutInflater.from(context); 
    Log.i("DEBUG MENU - CONSTRUCTOR", inflater.toString()); 
    this.data = data; 
    for(Menu menu: this.data){ 
     Log.i("DEBUG MENU - CONSTRUCTOR", menu.menu); 
    } 
} 

@Override 
public MenuViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { 
    View view = inflater.inflate(R.layout.row_menu, parent, false); 
    MenuViewHolder holder = new MenuViewHolder(view); 
    return holder; 
} 

@Override 
public void onBindViewHolder(MenuViewHolder holder, int position) { 
    Log.i("DEBUG MENU", "onBindViewHolder"); 
    Menu current = data.get(position); 
    holder.title.setText(current.menu); 
} 

@Override 
public int getItemCount() { 
    return 0; 
} 

class MenuViewHolder extends RecyclerView.ViewHolder { 
    TextView title; 
    ImageView icon; 

    public MenuViewHolder(View itemView) { 
     super(itemView); 
     title = (TextView) itemView.findViewById(R.id.menuText); 
    } 
}

मेरे कस्टम पंक्ति एक्सएमएल:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:orientation="horizontal" android:layout_width="match_parent" 
android:layout_height="match_parent"> 

<TextView 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:id="@+id/menuText" 
    android:text="Dummy Text" 
    android:layout_gravity="center_vertical" 
    android:textColor="#222"/>

और मेरे टुकड़ा:

public NavigationFragment() { 
    // Required empty public constructor 
} 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    mUserLearnedDrawer = Boolean.valueOf(readFromPreferences(getActivity(), KEY_USER_LEARNED_DRAWER, "false")); 
    if (savedInstanceState != null) { 
     mFromSavedInstaceState = true; 
    } 
} 

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, 
         Bundle savedInstanceState) { 
    // Inflate the layout for this fragment 

    View view = inflater.inflate(R.layout.fragment_navigation, container, false); 
    RecyclerView recyclerView = (RecyclerView) view.findViewById(R.id.drawer_list); 
    MenuAdapter adapter = new MenuAdapter(getActivity(), getData()); 
    recyclerView.setLayoutManager(new LinearLayoutManager(getActivity())); 
    recyclerView.setAdapter(adapter); 
    return view; 
}
