在您的 getChildrenCount 中，您的组头将增加到 1，例如：

@Override
public int getChildrenCount(int groupPosition) {
    return "your children group count" + 1;
}

并在 getChildView 中检查组的第一个孩子并返回组的标题，例如

@Override
public View getChildView(int groupPosition, final int childPosition,
        boolean isLastChild, View convertView, ViewGroup parent) {
    if(childPosition == 0){
         return "your header of group view";
    }
    // your original code here, note that, the childPosition is increased to 1
}

希望这有帮助。
