Answer 1

仍然不确定什么是 imagehader，但要在 expandablelistview 标头中设置图像，您应该执行以下操作：

@Override
public View getGroupView(int listPosition, boolean isExpanded,
                         View convertView, ViewGroup parent) {
    if (convertView == null) {
        LayoutInflater layoutInflater = (LayoutInflater) this.context.
                getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        convertView = layoutInflater.inflate(R.layout.your_layout, null);
    }

    ImageView imageheader = (ImageView) convertView.findViewById(R.id.imageheader);
    return convertView;
}
