ListView.getChildAt() 获取不在屏幕上的子视图
嗨，我有一个可扩展的列表视图，当我增加扩展它时它会滚动。然后我尝试检索所有孩子，但它给了我当前在屏幕上的孩子。我怎样才能得到不在屏幕上的孩子。 http://groups.google.com/group/android -developers/browse_thread/thread/7543f93b105c156e?fwc=1 我读了这个查询，但不明白如何重写 getview 方法来获取这些元素。我的 getgroupview 方法是这样的。
public View getGroupView(int groupPosition, boolean isExpanded, View convertView,
ViewGroup parent) {
View v;
v=convertView;
if(v==null)
{LayoutInflater vi = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = vi.inflate(R.layout.group, null);
}
return v;}
我应该做哪些修改才能得到另一个孩子

你不能。它们不存在。
ListView和ExpandableListView回收行。You can't. They do not exist.
