ExpandableListView简单实现商品列表折叠


在日常开发,有可能会遇到需要一些可以展开的列表,比如QQ的好友列表。
但是,用Android的该怎么做呢?其实在我没有接触过ExpandableListView类之前,
都是自定义控件继承于ListView或者ListView嵌套ListView来实现的,
当然也不推荐大家这样使用, 这样使用会降低app页面的加载速度和性能. 然后,
后来发现了Android也给我们提供了ExpandableListView类,完美实现这样类似的需求, 极大的方便了我们开发.

demo演示

Demo来自某个线上电商app的页面, 使用前先看看效果图

1. 如果子条目需要响应click事件,必需返回true

    @Override
    public boolean isChildSelectable(int groupPosition, int childPosition) {
        return true;
    }

2. 去除掉默认的关闭和打开状态的图片(系统默认的不好看)

android:groupIndicator="@null"

3. 解决无法正常展开问题

//HorizontalScrollView
hsv_goods_list.setFocusable(false)
