Round corners ExpandableListView

Question

Hi I am creating an ExpandableListView which should have round corners card for group item when it is not expanded. The round corners card must become the background of a group and it's children once it is expanded. Attached the image. How should it be done.

Thanks

Hi @leonardkraemer, I have defined what I am looking for. I am not getting any idea how to achieve this — Shane, Sep 17 '18 at 14:34

Nope that is round corners background for a view. In my case a header/group must have all four corners round when it is not expanded. But upper corners of group/header must be round with last child lower corners round while a group is expanded. Remember it is an Expandable list view. — Shane, Sep 17 '18 at 14:57
I think you can achieve what you want, when you set the background of your group to some of those answers. — leonardkraemer, Sep 17 '18 at 15:00

If your adapter is extends BaseExpandableListAdapter, then try:

@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;
}

Please make the layouts accordingly. Hope that helps!
