一、ExpandableListView介绍 　　　　一个垂直滚动的显示两个级别（Child,Group）列表项的视图，列表项来自ExpandableListAdapter 。组可以单独展开。 　　1.重要方法 　　　　　　expandGroup(int groupPos) :在分组列表视图中展开一组，　　　　　　setSelectedGroup(int groupPosition) ：设置选择指定的组。　　　　　　setSelectedChild(int groupPosition, int childPosition, boolean shouldExpandGroup) ：设置选择指定的子项。　　　　　　getPackedPositionGroup(long packedPosition) ：返回所选择的组　　　　　　getPackedPositionForChild(int groupPosition, int childPosition) ：返回所选择的子项　　　　　　getPackedPositionType(long packedPosition) ：返回所选择项的类型（Child,Group）　　　　　　isGroupExpanded(int groupPosition) :判断此组是否展开　　2.代码：ExpandableListContextMenuInfo menuInfo=(ExpandableListContextMenuInfo)item.getMenuInfo();String title=((TextView)menuInfo.targetView).getText().toString();int type=ExpandableListView.getPackedPositionType(menuInfo.packedPosition);if (type==ExpandableListView.PACKED_POSITION_TYPE_CHILD) {int groupPos =ExpandableListView.getPackedPositionGroup(menuInfo.packedPosition);int childPos =ExpandableListView.getPackedPositionChild(menuInfo.packedPosition);二、ExpandableListAdapter　　　　一个接口，将基础数据链接到一个ExpandableListView。此接口的实施将提供访问Child的数据（由组分类），并实例化的Child和Group。 getChildId(int groupPosition, int childPosition) 获取与在给定组给予孩子相关的数据。 　　　　getChildrenCount(int groupPosition) 返回在指定Group的Child数目。
