如果您的适配器是extends BaseExpandableListAdapter，请尝试：

@Override
public View getGroupView(int groupPosition, boolean isExpanded, View view, ViewGroup viewGroup) {
    LayoutInflater inflater = LayoutInflater.from(context);
    if(isExpanded){
        view = inflater.inflate(R.layout.two_up_round_corners_group, null);
    }else{
        view = inflater.inflate(R.layout.four_round_corners_group, null);
    }
    // Populate your view here.

    return view;
}

@Override
public View getChildView(int groupPosition, int childPosition, boolean isLast, View view, ViewGroup viewGroup) {
    LayoutInflater inflater = LayoutInflater.from(context);
    if(isLast){
        view = inflater.inflate(R.layout.two_bottom_round_corners_child, null);
    }else{
        view = inflater.inflate(R.layout.normal_child, null);
    }
    // Populate your view here.

    return view;
}

请相应地进行布局。希望有帮助！
