android中不错的ExpandableListView实例效果源码
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。

Apress-Pro-Android-Apps-Performance-Optimization-
I thank the team at Apress who made this book possible: Steve Anglin, Corbin Collins, Jim
Markham, and Jill Steinberg. Working with all of them was a real pleasure and I can with
confidence recommend them to any author.
I also want to thank the tech reviewers: Charles Cruz, Shane Kirk, and Eric Neff. They
provided invaluable feedback, often catching mistakes I would not have seen even after dozens of
readings.
To all my friends whom I did not get to see as often as I would have liked while I was working
on this book, I give my thanks too: Marcely, Mathieu, Marilen, Maurice, Katie, Maggie, Jean-René,
Ruby, Greg, Aline, Amy, and Gilles, I promise I will make up for the lost time. Last but not least, I
owe a lot to three people: Eddy Derick, Fabrice Bernard, and Jean-Louis Gassée. Sometimes all it
takes is an injured toe and a broken suitcase.
