Question

我的Android应用中有2个回收站视图，如下图所示：

一个实际上是另一个的父母。孩子是正方形的区域，在真正意义上应该是图像。现在，我在设置保存图像的子项的适配器时遇到问题。这是我到目前为止在“父”适配器上尝试的内容：

@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();
    }

我一直在为子适配器获取json数据。我从API获得的整个JSON看起来像：

查看您的问题我认为您需要实施Expandable RecyclerView 使用：

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

可扩展的RecyclerView顾名思义，可以扩展视图，里面有自己的子视图检查外部库

Expandable RecyclerView on Github

Android嵌套回收站视图
