CursorLoader与rawQuery [英] CursorLoader with rawQuery
问题描述
我寻找到我的应用程序执行CursorLoader但我有一个小问题,它似乎没有办法仅仅通过一个原始查询到CursorLoader构造。
我可能失去了一些东西的文档(和谷歌),因此,如果任何人都可以点我一个简单的方法来与CursorLoader类我会AP preciate它运行原始查询。否则,我将有可能与必要的功能,而我试图避免创建自己的CursorLoader类。
似乎没有办法仅仅通过一个原始查询到CursorLoader构造。
这是因为 CursorLoader
作品与内容提供商和内容提供商不支持 rawQuery()
。
因此,如果任何人都可以点我一个简单的方法来与CursorLoader类运行原始查询我会AP preciate吧。
这是不可能的,对不起。欢迎您来创建自己的 AsyncTaskLoader
击中SQLite数据库,并支持 rawQuery()
。事实上,我可能会在今年晚些时候写这些中的一个,如果我没有看到任何人击败了我吧。
I'm looking into implementing CursorLoader in my app but I'm having a small issue that it seems that there isn't a way to just a pass a raw query to the CursorLoader constructor.
I maybe missing something in the documentation (and google), so if anybody can point me to a simple way to run a raw query with a CursorLoader class I would appreciate it. Otherwise I will have to probably create my own CursorLoader class with the necessary functionality, which I'm trying to avoid.
it seems that there isn't a way to just a pass a raw query to the CursorLoader constructor.
That is because CursorLoader
works with content providers, and content providers do not support rawQuery()
.
so if anybody can point me to a simple way to run a raw query with a CursorLoader class I would appreciate it.
That is impossible, sorry. You are welcome to create your own AsyncTaskLoader
that hits a SQLite database and supports rawQuery()
. In fact, I will probably write one of these later this year, if I don't see where anyone has beaten me to it.
