RecyclerView-：沒有連接適配器;跳繩佈局

-2

我一直在這裏閱讀不同的答案在計算器後，試圖實現他們的解決方案，但我仍然得到錯誤RecyclerView-：沒有連接適配器;跳繩佈局

public class Appetizer extends AppCompatActivity { 

    private RecyclerView recyclerView; 
     private AdapterFood mAdapter; 


    recyclerView = (RecyclerView)findViewById(R.id.lvaptzr); 
        mAdapter = new AdapterFood(Appetizer.this,data); 
        recyclerView.setAdapter(mAdapter); 
        recyclerView.setLayoutManager(new LinearLayoutManager(Appetizer.this));

這是我的適配器類：

public class AdapterFood extends RecyclerView.Adapter<RecyclerView.ViewHolder> { 
    private Context context; 
    private LayoutInflater inflater; 
    List<DataFood> data = Collections.emptyList(); 
    DataFood current; 
    int currentPos=0; 

    public AdapterFood(Context context, List<DataFood> data){ 
     this.context=context; 
     inflater=LayoutInflater.from(context); 
     this.data=data; 
    } 

    @Override 
    public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { 
     View view=inflater.inflate(R.layout.list_item,parent,false); 
     Myholder holder=new Myholder(view); 
     return holder; 

    } 

    @Override 
    public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) { 
     Myholder myholder=(Myholder) holder; 
     DataFood current=data.get(position); 
     myholder.textFoodname.setText(current.foodName); 
     myholder.textPrice.setText("Rp. " + current.price); 
     myholder.textId.setText(current.foodId); 
     Glide.with(context).load("http://kelompokdua.hol.es/pic/" + current.foodImage) 
       .placeholder(R.mipmap.ic_launcher) 
       .error(R.mipmap.ic_launcher) 
       .into(myholder.ivFood); 
    } 

    @Override 
    public int getItemCount() { 
     return data.size(); 
    } 

    class Myholder extends RecyclerView.ViewHolder{ 
     TextView textFoodname,textPrice,textId; 
     ImageView ivFood; 

     public Myholder(View itemView) { 
      super(itemView); 
      textFoodname=(TextView) itemView.findViewById(R.id.textFoodname); 
      ivFood=(ImageView)itemView.findViewById(R.id.ivFood); 
      textId=(TextView)itemView.findViewById(R.id.textid); 
      textPrice=(TextView) itemView.findViewById(R.id.textPrice); 
     } 
    } 
}

我嘗試任何方法，但我無法解決探針。我做錯了什麼？

檢查'data.size == 0' –

組佈局管理器上面的設置適配器 – TUSHAR

，你在recyclerView設置適配器？如果您有異步請求，則必須在獲取數據刷新適配器後設置適配器爲空值。 –

你應該叫setLayoutManager前setAdapter。

recyclerView = (RecyclerView)findViewById(R.id.lvaptzr); 
    LinearLayoutManager mLayoutManager = new LinearLayoutManager(Appetizer.this); 
    recyclerView.setLayoutManager(mLayoutManager); // 1st 
    mAdapter= new AdapterFood(Appetizer.this,data); 
    recyclerView.setAdapter(mAdapter); // 2nd

這是不正確的方式來發布沒有任何描述的答案，什麼是OP問題，爲什麼這可能有幫助 –

@ShayanPourvatan請仔細檢查 –

mAdapter.setLinearLayoutManager（mLayoutManager）; mAdapter.setRecyclerView（mRecyclerView）;無法解析方法先生 – Fawwaz
