我正在尝试访问GroupView的textview,它显示ChildView中所选复选框的计数.

例如 – North是GroupView,下面带有复选框的列表是ChildView.我想每次点击复选框更新计数(18).我在复选框上应用了OnClickListner.我有自定义ExpanadableListViewAdapter扩展BaseExpandableListAdapter.

这是我的代码片段 –

@Override
public View getGroupView(int groupPosition,boolean isExpanded,View convertView,ViewGroup parent) {
    if (convertView == null) {
        convertView = LayoutInflater.from(parent.getContext()).inflate(R.layout.filter_expandable_list_group,parent,false);

        groupViewHolder = new GroupViewHolder();

        groupViewHolder.GroupName = (TextView) convertView.findViewById(R.id.group_name);
        groupViewHolder.GroupCount = (TextView) convertView.findViewById(R.id.group_count);
        groupViewHolder.rightArrow = (ImageView) convertView.findViewById(R.id.right_arrow);

        convertView.setTag(groupViewHolder);
    }else{
        groupViewHolder = (GroupViewHolder) convertView.getTag();
    }
    groupViewHolder.GroupName.setText(((OutletListData) getGroup(groupPosition)).getName());
    groupViewHolder.GroupCount.setText(""+((OutletListData) getGroup(groupPosition)).getOutletDatas().size());

    return convertView;
}

@Override
public View getChildView(final int groupPosition,final int childPosition,boolean isLastChild,final ViewGroup parent) {
    if (convertView == null) {
        convertView = LayoutInflater.from(parent.getContext()).inflate(R.layout.filter_expandable_list_child,false);

        childViewHolder = new ChildViewHolder();

        childViewHolder.childTextView = (TextView) convertView.findViewById(R.id.text1);
        childViewHolder.childCheckBox = (CheckBox) convertView.findViewById(R.id.checkBox);

        convertView.setTag(childViewHolder);
    }else{
        childViewHolder = (ChildViewHolder) convertView.getTag();
    }

    childViewHolder.childTextView.setText(((OutletData) getChild(groupPosition,childPosition)).getDealerName());
    childViewHolder.childCheckBox.setChecked(((OutletData) getChild(groupPosition,childPosition)).getSelected() == "1");
    childViewHolder.childCheckBox.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            boolean isChecked = ((CheckBox) v).isChecked();
            ApplicationController.getEventBus().post(((OutletData) getChild(groupPosition,childPosition)).getOutletID());
            if (isChecked) {
                ((OutletData) getChild(groupPosition,childPosition)).setSelected("1");
            } else {
                ((OutletData) getChild(groupPosition,childPosition)).setSelected("0");
            }
        }
    });
    return convertView;
}
