I see three approaches for you. As discussed in the comments the title of your question is misleading, so this is what I assume:

• you have a list of cards you want to display
• each card may have a list of comments

So the underlying problem is, that you have a two-dimensional data structure, which you want to display using a one-dimensional UI component, in your case a ListView.

You can solve your problem by:

1. Using an ExpandableListView, where the cards are the parent and the comments are the child elements. See [1] for an example.

2. Flatten your data hierarchy. So you only have a list of items, where the cards are somehow treated as "headers" or "separators" for your comments. You need to overwrite [2], in that case your Adapter is capable of returning two different views. In the getView() method you then need to do something like:

   if(list.get(position) instanceOf Card) return getCardView(...); else if(list.get(position) instanceOf Comment) return getCommentView(...);

3. Render the comments dynamically into a container within the card view. So in your layout file for your card view use a ViewGroup, e.g. a LinearLayout and give it a unique id, like "llComments". Have a separated layout file for your comments. Then in your current code you can inflate this file and just add the returned view to the container (llComments). I think this is the solution you are looking for. So, in your code, do something like:

   View commentConvertView = inflater.inflate(R.layout.list_item_comment, ...); ViewGroup comments = (ViewGroup) convertView.findViewById(R.id.llComments); comments.removeAllView; for(list.get(position).getComments()){ //bind the data to commentConvertView comments.add(commentConvertView); }
