推荐答案

不知道你的目标的，但这里有什么想法

Not sure what you're aiming for but here's an idea

通过你在你的主要活动得到了您的自定义列表

Pass the list you got in your main activity to your custom list

MyExpandableListAdapter myAdapter = new MyExpandableListAdapter(expandableList);

在自定义列表类方法：

in your custom list class methods:

private ExpandableListView exp;

public MyExpandableListAdapter(ExpandableListView exp)
{
    this.exp = exp;
}

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

    if (convertView == null)
    {
        LayoutInflater infalInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        convertView = infalInflater.inflate(R.layout.list_child, null);
    }

    exp.setDividerHeight(0);

    return convertView;

}


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

    if (convertView == null)
    {
        LayoutInflater infalInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        convertView = infalInflater.inflate(R.layout.list_row, null);
    }

    exp.setDividerHeight(20);

    return convertView;
}

例如，本应群体，而不是孩子的之间添加间隔

for example, this should add spacing between groups and not the childs
