Android的嵌套循环器浏览

我在我的Android应用2层回收的意见，如下图所示：Android的嵌套循环器浏览

一个实际上是其他的父母。孩子是真正意义上的广场应该是图像的区域。现在，我在设置包含图像的孩子的适配器时遇到问题。这就是我想要到目前为止“父”适配器上：

@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(); 
    }

我被困在获得JSON数据为孩子适配器。整个JSON我从我的API获取的样子：

看你的问题，我认为你需要实现可扩展RecyclerView 使用：顾名思义的

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

扩展RecyclerView视图可以扩展它具有内部检查自己的子视图这里的外部库

Expandable RecyclerView on Github
