从expandable中获取点击的子项

用害人的百度找了半天没找到，去stackoverflow查了一下找到的解决方法，直接上代码

OnChildClickListener stvClickEvent = new OnChildClickListener() {

@Override
public boolean onChildClick(ExpandableListView parent, View v, int groupPosition, int childPosition, long id) {
parent.getExpandableListAdapter().getChild(groupPosition, childPosition);//这个就是内容了
return false;
}
};

弄了几个小时才解决。转载注明出处http://blog.csdn.net/amazing_alex/article/details/40512239

当然，用OnChildClickListener，子项可点击的回调一定要true

另：

(if you want the data of a child, or .getGroup(groupPosition) if you want the data from the group) view instead of:

v.toString()
