从Resources对象检索所有Drawable资源 [英] Retrieving all Drawable resources from Resources object

问题描述

在我的Android项目中，我想遍历Drawable资源的整个集合.通常，您只能使用以下方式通过其ID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，我想获得所有Drawable资源，而我不会事先知道它们的ID.给定项目中的资源后，是否可以循环浏览一个集合或一种获取资源ID列表的方法?

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，在Java中，我有办法从R.drawable静态类中提取所有属性值吗?

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

推荐答案

如果发现自己想要这样做，可能是在滥用资源系统.看看资产和 AssetManager 遍历.apk中包含的文件.

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.
