Android drawable 目录可以包含子目录吗? [英] Can the Android drawable directory contain subdirectories?

问题描述

在 Android SDK 文档中，所有与 @drawable/my_image xml 语法一起使用的示例都直接处理存储在我项目的 res/drawable 目录中的图像.

In the Android SDK documentation, all of the examples used with the @drawable/my_image xml syntax directly address images that are stored in the res/drawable directory in my project.

我想知道在 drawable 目录中创建子目录是否明确是不行的.

I am wondering if it is explicitly not okay to create a sub directory within the drawable directory.

例如，如果我有以下目录布局:

For example, if I had the following directory layout:

res/drawable
-- sandwiches
  -- tunaOnRye.png
  -- hamAndSwiss.png
-- drinks
  -- coldOne.png
  -- hotTea.png

我可以将金枪鱼沙拉三明治的图片引用为@drawable/sandwiches/tunaOnRye

Could I reference the image of a tuna salad sandwich as @drawable/sandwiches/tunaOnRye

或者我是否必须在 drawable 目录中保持层次结构平坦.

Or do I have to keep the hierarchy flat in the drawable directory.

推荐答案

不，资源机制不支持可绘制目录中的子文件夹，所以是的 - 您需要保持该层次结构平坦.

No, the resources mechanism doesn't support subfolders in the drawable directory, so yes - you need to keep that hierarchy flat.

您显示的目录布局将导致没有可用的图像.

The directory layout you showed would result in none of the images being available.

从我自己的实验来看，在 res/drawable 文件夹内有一个包含任何项目的子文件夹，将导致资源编译器失败——阻止 R.java 文件无法正确生成.

From my own experiments it seems that having a subfolder with any items in it, within the res/drawable folder, will cause the resource compiler to fail -- preventing the R.java file from being generated correctly.
