Android的嵌套循環器瀏覽

我在我的Android應用2層回收的意見，如下圖所示：Android的嵌套循環器瀏覽

一個實際上是其他的父母。孩子是真正意義上的廣場應該是圖像的區域。現在，我在設置包含圖像的孩子的適配器時遇到問題。這就是我想要到目前爲止「父」適配器上：

@Override 
    public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { 
     View v = LayoutInflater.from(parent.getContext()) 
       .inflate(R.layout.feed_list_row, parent, false); 

     // Set the view to the ViewHolder 
     MyViewHolder holder = new MyViewHolder(v); 

     holder.mHorizontalListView.setHasFixedSize(false); 
     holder.mHorizontalListView.setHorizontalScrollBarEnabled(true); 

     // use a grid layout manager 
     GridLayoutManager mLayoutManager = new GridLayoutManager(parent.getContext(), 3); 
     holder.mHorizontalListView.setLayoutManager(mLayoutManager); 

     return holder; 
    } 

    @Override 
    public void onBindViewHolder(MyViewHolder holder, int position) { 
     FeedItem feedItem = feedItems.get(position); 
     holder.name.setText(feedItem.getName()); 
     holder.timestamp.setText(feedItem.getTimeStamp()); 
     holder.profilePic.setImageUrl(feedItem.getProfilePic(), imageLoader); 

     List<FeedPhoto> feedItemPhotos = new ArrayList<>(); 

     feedPhotosAdapter = new FeedPhotosAdapter(mContext, feedItemPhotos); 
     holder.mHorizontalListView.setAdapter(feedPhotosAdapter); 
     feedPhotosAdapter.notifyDataSetChanged(); 
    }

我被困在獲得JSON數據爲孩子適配器。整個JSON我從我的API獲取的樣子：

     "profile_pic": "http://api.androidhive.info/feed/img/lincoln.jpg",

看你的問題，我認爲你需要實現可擴展RecyclerView 使用：顧名思義的

compile 'com.bignerdranch.android:expandablerecyclerview:2.0.3'

擴展RecyclerView視圖可以擴展它具有內部檢查自己的子視圖這裏的外部庫

Expandable RecyclerView on Github
