Implementing your own filtered searching can be annoying, tricky, and buggy if not done correctly. 如果执行不正确，实施自己的筛选搜索可能会很烦人，棘手且容易出错。 Unfortunately Android does not provide a filterable adapter for use with the ExpandableListView which means you need to roll your own solution. 不幸的是，Android没有提供与ExpandableListView一起使用的ExpandableListView过滤适配器，这意味着您需要推出自己的解决方案。 Rather then going through all that pain, I suggest using the RolodexArrayAdapter . 建议您使用RolodexArrayAdapter ，而不要经历所有的痛苦。 It's a full fledged ExpandableListAdapter that adds filtering support (as well as many other things). 这是一个完整的ExpandableListAdapter ，增加了过滤支持（以及许多其他功能）。 Additionally there's a demo app with plenty of example code to show the various ways in which to use it. 此外，还有一个演示应用程序，其中包含大量示例代码，以展示使用它的各种方式。
