I think it's more like RecyclerView. At least, i would use it in this case. The main reason is ViewHolder. Of course you can provide your own viewholder pattern implementaion, but RecyclerView forces you to use ViewHolder and provides stubs.

As far as i understand, you don't need to handle click on entire element, but you need to handle click on plus/minus button. So when you implement ViewHolder, simply add click listener for that view and show/hide content, like this:

class ChartViewHolder extends RecyclerView.ViewHolder {
    private TextView storeTitle;
    private ToggleButton toggleBtn;
    // other views

    public ViewHolder(View itemView) {
        super(itemView);
        storeTitle = (TextView) itemView.findViewById(R.id.title_id);
        toggleBtn = (ToggleButton) itemView.findViewById(R.id.toggle_id);
        // other views

        toggleBtn.setOnCheckedChangeListener(new OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton toggleButton, boolean isChecked) {
                if(isChecked) {
                    // make content visible
                } else {
                    // make conent invisible
                }
            }
        });
    }
}

If you need animation for expanding/collapsing you should look into Property animations

My answer is: Don't use expandable list adapter.

Your collection doesn't look like having sub collections(at least less then scrollable amount).Your rows just hide/show details of your data by expanding collapsing.

use a custom ListAdapter and make each item expand and show detail on a button click with an Animation (you can find height animation by googling).

I hope this helps you.

It is possible you should create a custom ExpandableListAdapter which extends BaseExpandableListAdapter. There are lots of tutorials. Check part 15 of this tutorial for example.
