在ExpandableListView中添加组项目之间的差距

Question

如何在组项目之间添加间隙(比方说20dp)ExpandableListView？我有自定义组布局RelativeLayout作为父级.向父母添加边距并没有帮助.

Answer 1

不确定你的目标是什么,但这是一个想法

将您在主活动中获得的列表传递到自定义列表

MyExpandableListAdapter myAdapter = new MyExpandableListAdapter(expandableList);

在自定义列表类方法中:

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,这应该在组之间添加间距而不是孩子
