如何在RecyclerView中显示Firebase Parents元素

Question

只有一个父母但我不知道如何显示父母（食物）时，我可以显示子元素吗？

This is an image of Firebase Database:

代码：

private void loadOrders(String restaurantId) {
    adapter = new FirebaseRecyclerAdapter<Request, OrderViewHolder>(
            Request.class,
            R.layout.order_layout,
            OrderViewHolder.class,
            requests
    ) {
        @Override
        protected void populateViewHolder(OrderViewHolder viewHolder, Request model, int position) {
            viewHolder.txtOrderId.setText(adapter.getRef(position).getKey());
            viewHolder.txtOrderStatus.setText(Common.convertCodeToStatus(model.getStatus()));
            viewHolder.txtOrderAddreess.setText(model.getAddress());
            viewHolder.txtOrderPhone.setText(model.getUserId());
            viewHolder.setItemClickListener(new ItemClickListener() {
                @Override
                public void onClick(View view, int position, boolean isLongClick) {

                }
            });
        }
    };
    adapter.notifyDataSetChanged();
    recyclerView.setAdapter(adapter);
}

Answer 1

我认为最简单的方法是自定义您的Request.class，例如：

public class Request{
   private List<Food> foods;
}

您的Food.class内部类似于：

public class Food{
   private String discount;
   private String productName;

   // get & set method here
}

然后您可以简单地获得

之类的食物

model.getFoods().get({position that you want}).getProducName();
