Just assume that the child element of every group is a list of size equal to 1 . So, other parts of the adapter should be as usual with the exception of getChildView() and getChildrenCount() . In addition you may use the same object type as group and child.

    @Override
    public View getChildView(int groupPosition, int childPosition, boolean isLastChild, View rowView, ViewGroup parent) {
        //String url = mList.get(groupPosition).getChildList().get(childPosition);
        String url = mList.get(groupPosition).getUrl();

        if (rowView == null) {
            LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            rowView = inflater.inflate(R.layout.fermata_adapter_body, null);
            mWebView = (WebView) rowView.findViewById(R.id....); 
            ...
        }
        mWebView.loadUrl(url);
        return rowView;
    }

    @Override
    public int getGroupCount() {
        return mList.size();
    }

    @Override
    public int getChildrenCount(int groupPosition) {
        return 1;//every group has 1 child
    }
    @Override
    public Object getChild(int groupPosition, int childPosition) {
        return mList.get(groupPosition);//or mList.get(groupPosition).getUrl();
    }
    @Override
    public Object getGroup(int groupPosition) {
        return mList.get(groupPosition);
    }

For better usability, you may need to use networking libraries like Volley to load the web content rather than simply saying mWebView.loadUrl(url)
