安卓：从获取资源对象的所有可绘制资源 [英] Android: retrieving all Drawable resources from Resources object
问题描述
在我的Android项目，我想通过绘制对象资源的整个集合循环。通常情况下，你只能通过它的ID使用类似检索特定的资源：
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)
不过，我想所有的绘制对象的资源，我的不会了解自己的ID提前。是否有收集我可以遍历或者一个办法让我的项目资源ID的特定资源的列表？
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，有没有办法，我在Java中，从 R.drawable 静态类提取所有属性值？
Or, is there a way for me in Java to extract all property values from the R.drawable static class?
推荐答案
如果你发现自己想要做到这一点，你可能滥用资源系统。看看资产和<一href="http://developer.android.com/reference/android/content/res/AssetManager.html"><$c$c>AssetManager如果你想遍历文件包含在你的apk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.
