Java Android SearchView小部件，其结果为列表项

任何人都可以给我一个解决方案，告诉我如何使用

searchView小部件（不在操作栏中）

根据用户在searchView中键入的内容显示结果列表。
我是开发android应用程序的新手，我想尝试创建一个可以从数据库检索数据的简单应用程序
我试图从互联网上搜索，我找到了

'searchView'

，我可以搜索数据
我从internet复制代码并修改某些部分。我阅读了代码，实际上我理解了一些代码，但不是全部，现在从

main活动

，我看到了

'onSearchRequested（）；'，然后在操作栏中以
搜索视图开始意图
我试图通过在布局中放置一个searchView小部件来修改代码，我想用它来代替
'onSearchRequested（）；'但我是股票，不知道如何显示结果。


这是跑步的样子：

actionbar中的搜索视图





我想把它改成：

具有列表项结果但不在操作栏中的搜索视图

请再说一遍，我只是一个新手，如果我的问题有问题，我真的很抱歉，我喜欢编程，我只是想学习。无论如何，非常感谢你！！！任何帮助都将不胜感激

没什么大不了的。如果您知道CustomListView，那么对您来说很容易。
不理解整个问题，但您可能想忘记
