BitmapFactory.decodeResource and drawable* folders
提问by Thomas Calc
I am wondering if decodeResource (Resources res, int id, BitmapFactory.Options opts)takes into account the drawable-ldpi,mdpi,hdpi etc. folders.
我想知道是否decodeResource (Resources res, int id, BitmapFactory.Options opts)考虑了 drawable-ldpi、mdpi、hdpi 等文件夹。
I checked the source code, and it doesn't look like that, but I may be missing something.
我检查了源代码，它看起来不像，但我可能遗漏了一些东西。
(Generally, where are the R.drawable. resolved in Android source? I was unable to find it.)
（一般来说，Android 源中的 R.drawable. 在哪里解析？我找不到它。）

Yes it takes it into account. For example if you do :
是的，它考虑到了它。例如，如果你这样做：
Resources res = getContext().getResources();
int id = R.drawable.image;
Bitmap b = BitmapFactory.decodeResource(res, id);
The bitmap will be different if "image" is present in all of the drawables folders.
So I think using the overloaded method decodeResource (Resources res, int id, BitmapFactory.Options opts)will work in the same way.
如果所有 drawables 文件夹中都存在“图像”，则位图将有所不同。所以我认为使用重载方法decodeResource (Resources res, int id, BitmapFactory.Options opts)会以同样的方式工作。
