如何在可扩展列表视图中使用imageheader？

public View getGroupView(int groupPosition, boolean isExpanded,
        View convertView, ViewGroup parent) {



    return convertView;
}

Answer 1

仍然不确定什么是imagehader，但要在expandablelistview标头中设置图像，你应该这样做：

@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;
}
