活动必须执行某些操作 - 并实际显示结果。我刚刚按照我昨天问的一个问题的答案所建议的写了一个 尝试使用 runQueryOnBackgroundThread 过滤 ListView 但没有任何反应 - 我错过了什么?

可搜索< /code> 获取查询字符串后需要做更多的事情。例如,在我的活动中,在获取查询字符串后,我执行以下操作:
该方法如下所示:
成员 myDbHelper 在我的数据库中查询已传入查询字符串的国家/地区并将其显示在列表中。我的活动有一个如下所示的布局:
您可能不需要
setViewBinder
调用 - 我需要它,因为我正在将国家/地区代码字段转换为国旗图标。Your
Searchable
activity has to do something - and actually display results.I just wrote one as suggested by an answer to a question I asked yesterday Trying to filter a ListView with runQueryOnBackgroundThread but nothing happens - what am I missing?
Look at this documentation for how to integrate with the built in search support: Using the Android Search Dialog and look at this article on how to offer suggestions as the customer types: Adding Custom Suggestions
Your class
Searchable
needs to do a bit more after getting the query string. For example in my activity after getting the query string I do this:and that method looks like this:
The member myDbHelper queries my database for countries that have the passed in query string and displays them in a list. My activity has a layout that looks like this:
You can probably do without the
setViewBinder
call - I need that because I am translating the country code field into a flag icon.
