距离上次更新博客，时隔略长，诸事繁琐，赶在去广州答辩之前，分享下安卓 android 中的一个 列表收缩 类---ExpandableListView
先上效果图：
如果想直接看实现此页面的代码请下滑到 红线 下
关于这个类的具体各函数的使用说明，这里不作详细说明，提供一个链接http://www.apkbus.com/android-124715-1-1.html，里面有关于此类的详细介绍。
我在这里主要通过源代码的注释和必要的说明，说明如何实现自定义的收缩列表。
必要的函数：
0->
1 ExpandableListView expandListView = (ExpandableListView) this.findViewById(R.id.ecpandable); 2 expandListView.setGroupIndicator(null);//去掉默认的下指箭头 3 expandListView.setDivider(null);//去掉下行线
1->
1 @Override 2 public int getGroupCount() { 3 //用于返回大标题的数目，例如我上面的图片，共有7个大标题 4 return armTypes.length; 5 //armTypes 是用来存放大标题的数组，自定义 6 }
2->
1 @Override 2 public int getChildrenCount(int groupPosition) { 3 //用来返回一个大标题内的字标签数目，传入参数 groupPosition为当前 4 //大标题的下标，从0开始 5 return arms_two[groupPosition].length; 6 //arms_two 是自定义的，存放子标签的 二维 数组 7 }
//对应上面，这个二维字符串数组共有 7 行，每行对应一个大标签 //每行的列数是子标签数，对应当前大标签，有多少个就是有多少个孩子 private String[][] arms_two = new String[][]{ // {"班车列表(30分钟/班)","清记甜品","石头城","贝壳屋",}, //0~-- {"小a","清记甜品","石头城","贝壳屋",}, {"小c","清记甜品","石头城","贝壳屋","羊肉丁",}, {"小d",}, {"小e",}, {"小f",}, {"小aa",}, };
3->
//返回当前的大标签数目，对应上面的 getGroupCount 函数，传入的是谁 // 返回的就是对应谁的数目，上面是armTypes，那么就是它的数目 @Override public long getGroupId(int groupPosition) { return groupPosition; //注意，它是从0下标开始的 }
4->
//返回对应的每个大标签的 子标签数目，传入的 groupPosition 是当前的大 //标签下标，.length 就是当前行的列数 @Override public int getChildrenCount(int groupPosition) { return arms_two[groupPosition].length; }
5->
@Override public View getGroupView(int groupPosition, boolean isExpanded,View convertView, ViewGroup parent) { //返回大标签对应的 布局 视图，可以纯代码，也可以使用 xml 布局文件 //使用 xml 布局文件例子 RelativeLayout group = (RelativeLayout) RelativeLayout.inflate(getBaseContext(), R.layout.extend_group, null); return group; }
6->
@Override public View getChildView(int groupPosition, int childPosition, boolean isLastChild,View convertView, ViewGroup parent) { // 返回 子标签显示的 布局 视图，可以纯 代码，也可以 使用xml 布局文件 //xml 布局例子 LinearLayout child = (LinearLayout) LinearLayout.inflate(getBaseContext(), R.layout.extend_child, null); //建议使用listView return child; }
----------------------------------*********必要的函数分析完毕*********--------------------------------------

OK，觉得还可以的话，麻烦帮忙点下右下角的推荐。
