使用操作栏上的Searchview在列表视图中搜索

Question

我有一个活动，从sql server数据库列出listview上的客户端，我已经实现了searchview ..但我不知道如何实现查询从listview中搜索客户端名称..可以有人帮帮我??

这是我的活动代码，其中列表是：

Answer 1

关于模型 - 视图 - 控制器方法，您需要做的就是创建一个模型，其中包含与您的搜索匹配的数据，并将其交给将显示它的视图（列表视图）。

Answer 2

您可能需要一个setOnQueryTextListener，可以在SearchView中写入文字时过滤结果。

现有的帖子很好地解释了这一点，Implementing SearchView in action bar。
