现在我们可以很容易地使用JetBrains插件“Android文件分组”

Android文件分组

你可以用gradle做到这一点。我做了一个演示项目来展示如何做到这一点。

诀窍是使用gradle的能力来合并多个资源文件夹，并设置res文件夹以及sourceSets块中的嵌套子文件夹。

奇怪的是，在声明容器资源文件夹的子资源文件夹之前，您不能声明该文件夹。

下面是构建中的sourceSets块。演示中的Gradle文件。注意，先声明子文件夹。

sourceSets {
    main {
        res.srcDirs = [
            'src/main/res/layouts/layouts_category2',
            'src/main/res/layouts',
            'src/main/res'
        ]
    }
}

另外，实际资源文件(png、xml布局等)的直接父文件仍然需要与规范相对应。

不能有子目录(很容易)，但可以有额外的资源文件夹。很惊讶没有人提到它，但是保留默认的资源文件夹，并添加更多:

    sourceSets {
        main.res.srcDirs += ['src/main/java/XYZ/ABC']
    }

I think the most elegant solution to this problem (given that subfolders are not allowed) is to prepend the file names with the name of the folder you would have placed it inside of. For example, if you have a bunch of layouts for an Activity, Fragment, or just general view called "places" then you should just prepend it with places_my_layout_name. At least this solves the problem of organizing them in a way that they are easier to find within the IDE. It's not the most awesome solution, but it's better than nothing.

检查Bash Flatten Folder脚本，该脚本将文件夹层次结构转换为单个文件夹

在一个模块中，要拥有风味、风味资源(布局、值)和风味资源的组合，主要要记住两件事:

When adding resource directories in res.srcDirs for flavor, keep in mind that in other modules and even in src/main/res of the same module, resource directories are also added. Hence, the importance of using an add-on assignment (+=) so as not to overwrite all existing resources with the new assignment. The path that is declared as an element of the array is the one that contains the resource types, that is, the resource types are all the subdirectories that a res folder contains normally such as color, drawable, layout, values, etc. The name of the res folder can be changed.

一个例子是使用路径"src/flavor/res/values/strings-ES"，但是注意到实践层次结构必须有子目录值:

├── module 
   ├── flavor
      ├── res
         ├── values
            ├── strings-ES
               ├── values
                  ├── strings.xml
               ├── strings.xml
 

该框架精确地根据类型识别资源，这就是为什么通常已知的子目录不能被省略。

还要记住，flavor中的所有strings.xml文件将形成一个联合，这样资源就不能被复制。反过来，这个组成该类型文件的联合在模块的主文件之前具有更高的优先级。

flavor {
        res.srcDirs += [
            "src/flavor/res/values/strings-ES"
        ]
}

将strings-ES目录视为包含资源类型的定制资源。
