ExpendableListView的子部分中的按钮无法正常工作

Question

Screenshot

篮球队是第一个具有n个子元素的组元素。当我单击“是”或“否”或“无”时，我需要更改按钮的颜色。颜色已更改。
Please find in this screenshot

但是当我单击这些按钮时，也会自动单击第二组元素（足球队）按钮。请给我一个解决方案。我已经在此处附加了CustomExpandableAdapter。

public class CustomExpandableListAdapter extends BaseExpandableListAdapter /*implements ExpandableListView.OnChildClickListener */{

   // Button btn_yes,btn_no,btn_none;
    private Context context;
    private List<String> expandableListTitle;
    private HashMap<String, List<String>> expandableListDetail;

    public CustomExpandableListAdapter(Context context, List<String> expandableListTitle,
                                       HashMap<String, List<String>> expandableListDetail) {
        this.context = context;
        this.expandableListTitle = expandableListTitle;
        this.expandableListDetail = expandableListDetail;
    }

    @Override
    public Object getChild(int listPosition, int expandedListPosition) {
        return this.expandableListDetail.get(this.expandableListTitle.get(listPosition))
                .get(expandedListPosition);
    }
