如何在独立组的ExpandableListView中找到子位置？

Question

因此，我试图创建一个包含多个父级和子级的可扩展列表。我已经找到了如何找到一组孩子的位置，但是我却无法找到如何将其扩展到其他父母的位置。这是我的代码，

public View getChildView(int groupPosition, final int childPosition, boolean isLastChild, View convertView, ViewGroup parent) {
        final String childText = (String)getChild(groupPosition,childPosition);
        if(convertView==null){
            LayoutInflater inflater = (LayoutInflater)this.context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            convertView = inflater.inflate(R.layout.list_item, null);
        }
        TextView txtListChild = (TextView)convertView.findViewById(R.id.lblListItem);
        txtListChild.setText(childText);



        convertView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if(childPosition==0){
                    Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse("https://www.reddit.com/r/GlobalOffensive/"));
                        context.startActivity(i);
                }
                else if (childPosition ==1){
                    Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse("https://csgolounge.com/"));
                    context.startActivity(i);
                }
                else if (childPosition ==2){
                    Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse("https://www.reddit.com/r/RocketLeague/"));
                    context.startActivity(i);}
                else if (childPosition ==3){
                    Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse("https://rocket-league.com/trading"));
                    context.startActivity(i);}


            }
        });


        return convertView;
    }

每个组中有两个孩子，这仅注册了第一个父组。任何帮助表示赞赏！！！！
