Intent extras arent'passed in my modified master/detail template

我試圖修改Android Studio中的庫存主/明細模板。我的主要目標是嘗試正確顯示簡單的List<Obj>，我在onCreate()中手動填充。我的問題是，應該從ListActivity傳遞到DetailActivity（然後傳遞給片段）的附加內容沒有通過。Intent extras arent'passed in my modified master/detail template

的完整代碼here

我懷疑有一些錯誤的RecyclerView適配器（和持有人），我體改。我也不喜歡脫銷DummyContent類。

我也想知道是否最好刪除這個DummyContent類並創建自己的數據源，或者在所謂的真實生活中修改現有的Dummy內容源更簡單更方便。

如果您希望在這裏粘貼更多的代碼片段，請告訴我，預先感謝您的幫助。

public class SimpleItemRecyclerViewAdapter 
     extends RecyclerView.Adapter<SimpleItemRecyclerViewAdapter.ViewHolder> { 

    private final List<Obj> mValues; 

    public SimpleItemRecyclerViewAdapter(List<Obj> items) { 
     mValues = items; 
    } 

    @Override 
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { 
     View view = LayoutInflater.from(parent.getContext()) 
       .inflate(R.layout.data_list_content, parent, false); 
     return new ViewHolder(view); 
    } 

    @Override 
    public void onBindViewHolder(final ViewHolder holder, int position) { 
     holder.obj = mValues.get(position); 

     holder.name.setText(holder.obj.getName()); 
     holder.image.setText(holder.obj.getImage()); 

     holder.mView.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       if (mTwoPane) { 
        Bundle arguments = new Bundle(); 
        arguments.putString(Keys.KLUCZ, holder.obj.getName()); // tutaj musze przeslac Id 
        DataDetailFragment fragment = new DataDetailFragment(); 
        fragment.setArguments(arguments); 
        getSupportFragmentManager().beginTransaction() 
          .replace(R.id.data_detail_container, fragment) 
          .commit(); 
       } else { 
        Context context = v.getContext(); 
        Intent intent = new Intent(context, DataDetailActivity.class); 
        intent.putExtra(Keys.KLUCZ, holder.obj.getName()); 
        Log.d("DataListActivity", "obj.getName = "+holder.obj.getName()); 
        context.startActivity(intent); 
       } 
      } 
     }); 
    } 

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

    public class ViewHolder extends RecyclerView.ViewHolder { 
     public final TextView name; 
     public final TextView image; 
     public final View mView; 
     public Obj obj; 

     public ViewHolder(View view) { 
      super(view); 
      mView = view; 
      name = (TextView) view.findViewById(R.id.id); 
      image = (TextView) view.findViewById(R.id.content); 
     } 

    }

和接收活動：

if (savedInstanceState == null) { 
     // Create the detail fragment and add it to the activity 
     // using a fragment transaction. 
     Bundle arguments = new Bundle(); 
     arguments.putString(Keys.KLUCZ, 
       getIntent().getStringExtra(Keys.KLUCZ)); 
     DataDetailFragment fragment = new DataDetailFragment(); 
     fragment.setArguments(arguments); 
     getSupportFragmentManager().beginTransaction() 
       .add(R.id.data_detail_container, fragment) 
       .commit(); 
    }

發現它自己：我是不正確的實例化我的OBJ對象：

是：

mItem = new Obj(Keys.KLUCZ, "some string");

應該是：

mItem = new Obj(getArguments().getString(Keys.KLUCZ), "Jakies nazwisko");
