嘗試使用FirebaseUI時「無法解析構造函數FirebaseRecyclerAdapter」

Question

我正在使用FirebaseUI的FirebaseRecyclerAdapter as described in github。

但我得到錯誤（無法解析構造函數FirebaseRecyclerAdapter）。嘗試了一切可能，但仍然得到相同的錯誤。

這裏是我的活動

Firebase ref = new Firebase("https://myapp.firebaseio.com/shoplist"); 

RecyclerView recyclerView; 
String enteredShopName; 

private FirebaseRecyclerAdapter<Chat, ChatHolder> mRecyclerViewAdapter; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 

    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); 
    setSupportActionBar(toolbar); 

    recyclerView = (RecyclerView) findViewById(R.id.recyclerView); 
    recyclerView.setHasFixedSize(true); 
    recyclerView.setLayoutManager(new LinearLayoutManager(this)); 

    FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab); 
    fab.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 
      createDialog(); 
     } 
    }); 
} 

@Override 
protected void onStart() { 
    super.onStart(); 

    attachRecyclerViewAdapter(); 
} 

private void attachRecyclerViewAdapter() { 
    mRecyclerViewAdapter = new FirebaseRecyclerAdapter<Chat, ChatHolder>(
      Chat.class, R.layout.message, ChatHolder.class, ref) { 

     @Override 
     public void populateViewHolder(ChatHolder chatView, Chat chat, int position) { 
      chatView.setName(chat.getName()); 


     } 
    }; 

       } 
    }); 

    mRecyclerViewAdapter.setAdapter(mRecyclerViewAdapter); 
} 

private void createDialog() { 
    AlertDialog.Builder dialogBuilder = new AlertDialog.Builder(this); 
    LayoutInflater inflater = this.getLayoutInflater(); 
    final View dialogView = inflater.inflate(R.layout.addshop_dialog, null); 
    dialogBuilder.setView(dialogView); 

    final EditText randeephooda = (EditText) dialogView.findViewById(R.id.et_shopName); 

    enteredShopName = randeephooda.getText().toString(); 

    dialogBuilder.setTitle("Add Shop"); 
    dialogBuilder.setPositiveButton("Add", new DialogInterface.OnClickListener() { 
     public void onClick(DialogInterface dialog, int whichButton) { 
      //do something with edt.getText().toString(); 


      Chat chat = new Chat(enteredShopName); 
      ref.push().setValue(chat); 
     } 
    }); 

    dialogBuilder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() { 
     public void onClick(DialogInterface dialog, int whichButton) { 
      //pass 
     } 
    }); 

    AlertDialog b = dialogBuilder.create(); 
    b.show(); 
} 

我的POJO

String name; 

    public Chat() { 
    } 

    public Chat(String name) { 
     this.name = name; 

    } 

    public String getName() { 
     return name; 
    } 

我ViewHolder

public ChatHolder(View itemView) { 
     super(itemView); 
     mView = itemView; 
    } 

    public void setName(String name) { 
     TextView field = (TextView) mView.findViewById(R.id.shoprecyclerview_textView); 
     field.setText(name); 
    } 
} 

Answer 1

變化

mRecyclerViewAdapter.setAdapter(mRecyclerViewAdapter);//this line caused error 

至

recyclerView.setAdapter(mRecyclerViewAdapter);//Need to set adapter to the recyclerview 

完成。創建參考

Firebase ref = new Firebase("https://myapp.firebaseio.com/shoplist"); 

遷移到新的火力點代碼時

Answer 2

Please view answer here:

問題是使用舊的火力點代碼，並使用這個代替：

DatabaseReference rootRef = FirebaseDatabase.getInstance().getReference();
