Android ListView 打开子集
我想设计一个这样的项目，单击时会打开其他项目的子集，我只在我使用过的其他应用程序中看到它，并且找不到有关如何创建它的任何资源。有人知道怎么做吗？
谢谢。
I would like to design an item like this that opens a subset of other items when clicked, I have only seen it in other applications I've used, and I can't find any resources on how to create it. Does anyone know how to?
Thanks.

目前尚不清楚您是否想要创建如下所示的嵌套列表视图
，或者是否想要在用户单击某个项目时打开一个全新的列表。
如果你想使用嵌套列表视图看看这个问题： android 嵌套列表视图
如果你想打开一个新活动，然后使用列表视图创建第二个活动并在项目上单击打开它
Its not clear if you want to created Nested listviews that look like this
or if you want to open a completely new list when the user clicks on an item.
If you want to use a nested listview look at this question: android nested listview
And if you want to open a new activity, then create a 2nd activity with a listview and open that on an item click
也许您应该尝试看看
ExpandableListView。文档可从此处获取：
http://developer.android.com/reference/android/widget/ExpandableListView.html
如果您想添加一个可打开另一个列表的
ListView，您可以通过多种方式实现。我通过向ListView添加OnItemClickListener成功完成此操作，然后只需在ListView中加载一组新数据并使用invalidate()或通过设置新的Adapter。您甚至可以添加一些很酷的过渡或动画，并在动画完成时创建一个侦听器。很多很酷的想法:-)
Perhaps you should try to have a look at the
ExpandableListView.Documentation is available from here:
http://developer.android.com/reference/android/widget/ExpandableListView.html
If you wanted to add a
ListViewthat opens another list, you can do it in several ways. I've successfully done it by adding anOnItemClickListenerto theListViewand then simply load a new set of data in theListViewand update it usinginvalidate()or by setting a newAdapter.You could even add some cool transitions or animations, and create a listener for when the animation is completed. Lots of cool ideas :-)
