1、折叠的时候：
2、点击“可更新的应用(6)”，进行展开的时候：
3、实现步骤主要分为：
1>构建ExpandableListView布局，如
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<ExpandableListView
android:id="@+id/ecpandable"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
</LinearLayout>
2>集成BaseExpandableListAdapter，实现自己的Adapter，为此我们需要以下方法
public int getGroupCount();//所有折叠后的组个数，即与“可更新的应用(6)”同一级别的个数
public int getChildrenCount(int groupPosition);//每个组所具有的子集个数，即上图中类似“美图秀秀”等应用个数
public int getChildType(int groupPosition, int childPosition);//子集类别
public int getChildTypeCount();//子集个数
public Object getGroup(int groupPosition);//获得指定组
public Object getChild(int groupPosition, int childPosition);//获得指定组的子集
public long getGroupId(int groupPosition);//获得组ID
public long getChildId(int groupPosition, int childPosition);//获得子集ID
public View getGroupView(int groupPosition, boolean isExpanded, View convertView, ViewGroup parent);//获得组视图（用来展现组）
public View getChildView(int groupPosition, int childPosition, boolean isLastChild, View convertView, ViewGroup parent);//获得子集视图（用来展现子集）
3>基本初始化
mUpdateAdapter = new ExpandableListAdapter(this);
mUpdateAdapter.registerCallback(this);//注册回调函数
mListView.setAdapter(mUpdateAdapter);
mListView.setCacheColorHint(Color.TRANSPARENT);//点击时候不会变黑
mListView.setGroupIndicator(null);//去掉左边图标
mListView.expandGroup(ExpandableListAdapter.GROUP_UPDATE);//触发展开
mListView.expandGroup(ExpandableListAdapter.GROUP_IGNORE);//触发展开
4>装数且触发刷新列表
notifyDataSetChanged();
