Android AnimatedExpandableListView getGroupView groupposition始终显示0

Question

AnimatedExpandableListView getGroupView始终显示第0个位置，getCount显示6。并且它始终显示第0个位置值，并且不显示任何子项。任何人都建议我在下面的适配器源代码

中有什么问题

这是我的代码：

private class MenuAdapter extends AnimatedExpandableListView.AnimatedExpandableListAdapter {
        private LayoutInflater inflater;
        ArrayList<HashMap<String, ArrayList<CategoryObj>>> subCatArrayList;
        Context ct;
        public MenuAdapter(Context context) {
            inflater = LayoutInflater.from(context);
            ct=context;
        }

        public void setData(ArrayList<HashMap<String, ArrayList<CategoryObj>>> catList) {
            this.subCatArrayList = catList;
        }

        @Override
        public HashMap<String, ArrayList<CategoryObj>> getChild(int groupPosition, int childPosition) {
            return subCatArrayList.get(childPosition);
        }

        @Override
        public long getChildId(int groupPosition, int childPosition) {
            return childPosition;
        }

        @Override
        public View getRealChildView(int groupPosition, int childPosition, boolean isLastChild, View convertView, ViewGroup parent) {
            ChildHolder holder;
            if (convertView == null) {
                holder = new ChildHolder();
                convertView = inflater.inflate(R.layout.menu_sublist, parent, false);
                holder.mMenu_SubCategory = (TextView) convertView.findViewById(R.id.subcat_item);
                convertView.setTag(holder);
            } else {
                holder = (ChildHolder) convertView.getTag();
            }
            if(groupPosition == 0){
                holder.mMenu_SubCategory.setText(subCatArrayList.get(groupPosition).get("A").get(childPosition).getSubCat_name());
            }else if(groupPosition == 1){
                holder.mMenu_SubCategory.setText(subCatArrayList.get(groupPosition).get("B").get(childPosition).getSubCat_name());
            }else if(groupPosition == 2){
                holder.mMenu_SubCategory.setText(subCatArrayList.get(groupPosition).get("C").get(childPosition).getSubCat_name());
            }else if(groupPosition == 3){
                holder.mMenu_SubCategory.setText(subCatArrayList.get(groupPosition).get("D").get(childPosition).getSubCat_name());
            }else if(groupPosition == 4){
                holder.mMenu_SubCategory.setText(subCatArrayList.get(groupPosition).get("E").get(childPosition).getSubCat_name());
            }else if(groupPosition == 5){
                holder.mMenu_SubCategory.setText(subCatArrayList.get(groupPosition).get("F").get(childPosition).getSubCat_name());
