Android：从Resources对象中检索所有Drawable资源 [英] Android: retrieving all Drawable resources from Resources object

问题描述

在我的Android项目中，我想循环遍历 Drawable 资源的整个集合。通常，您只能通过其ID使用以下内容检索特定资源：

In my Android project, I want to loop through the entire collection of Drawable resources. Normally, you can only retrieve a specific resource via its ID using something like:

InputStream is = Resources.getSystem().openRawResource(resourceId)

但是，我想得到所有 Drawable 资源，其中我不会预先知道他们的ID。有没有一个集合我可以循环，或者一种方式来获得资源ID的列表给定的资源在我的项目？

However, I want to get all Drawable resources where I won't know their ID's beforehand. Is there a collection I can loop through or perhaps a way to get the list of resource ID's given the resources in my project?

或者，有一种方式为我Java从 R.drawable 静态类中提取所有属性值？

Or, is there a way for me in Java to extract all property values from the R.drawable static class?

推荐答案

p>如果你发现自己想这样做，你可能是误用资源系统。查看资产和 AssetManager 如果你想迭代包含在.apk中的文件。

If you find yourself wanting to do this you're probably misusing the resource system. Take a look at assets and AssetManager if you want to iterate over files included in your .apk.
