我想存储从资源文件夹（可绘制）到sqlite的图像路径，然后检索。我怎样才能做到这一点？Android商店从res文件夹到sqlite的图像路径
更新： 检索图像后，我有一个按钮在这里重新排序/排序列表视图。这就是为什么我需要将图像路径存储到sqlite。
这是我到目前为止已经试过：

在这里我已经声明的那些可绘制。我如何将他们的路径保存到sqlite，然后将它们显示在我的自定义列表视图上？有任何想法吗？非常感谢帮助。谢谢。
是的，我在想这个，但是当我要对我的列表视图进行排序时，它并没有改变它的位置。 – Dunkey
哦，所以你要重新排序列表视图中的数据？您能否更新您的问题，提供有关您希望自己的代码如何工作的信息，或者您想要完成的内容，以及包含您认为是否需要数据库支持的详细信息？ –
是的，我已经更新了我的问题。 – Dunkey
