解决方案 1: 使用 ExpandableListView 并在 group_child_layout 中取四个 ImageView(Whatever Buttons)。

分配相应的数据(例如,将电话号码值分配给 call_icon)。下面的例子:

 @Override
 public View getChildView(int groupPosition, int childPosition, boolean isLastChild, View convertView, ViewGroup parent) {

    ChildHolder childHolder = null;
    if (convertView == null) {
        LayoutInflater inflater = (LayoutInflater) context.getSystemService(context.LAYOUT_INFLATER_SERVICE);
        convertView = inflater.inflate(R.layout.item_group_child, parent, false);
        childHolder = new ChildHolder();
        convertView.setTag(childHolder);
    }
    else {
        childHolder = (ChildHolder) convertView.getTag();
    }

    /* Assign all the buttons their respective data from ContactData object*/

    return convertView;
}

解决方案 2: 使用 ExpandableListView 并在 group_child_layout 中取一个 RecyclerView(用于水平按钮列表)。下面的例子:

@Override
public View getChildView(int groupPosition, int childPosition, boolean isLastChild, View convertView, ViewGroup parent) {

    ChildHolder childHolder = null;
    if (convertView == null) {
        LayoutInflater inflater = (LayoutInflater) context.getSystemService(context.LAYOUT_INFLATER_SERVICE);
        convertView = inflater.inflate(R.layout.item_group_child, parent, false);
        childHolder = new ChildHolder();
        convertView.setTag(childHolder);
    }
    else {
        childHolder = (ChildHolder) convertView.getTag();
    }

    childHolder.horizontalListView = (RecyclerView) convertView.findViewById(R.id.buttons);
    LinearLayoutManager layoutManager = new LinearLayoutManager(context, LinearLayoutManager.HORIZONTAL, false);
    childHolder.horizontalListView.setLayoutManager(layoutManager);

    ButtonsAdapter horizontalListAdapter = new ButtonsAdapter(context, brands.get(groupPosition).buttons);
    childHolder.horizontalListView.setAdapter(horizontalListAdapter);

    return convertView;
}
