现在，我在'res/layout'文件夹内存储每个XML布局文件，因此管理小型项目是可行和简单的，但当有大型和繁重的项目的情况下，那么应该有一个层次结构和子文件夹内需要的布局文件夹。
如。
layout
-- layout_personal
-- personal_detail.xml
-- personal_other.xml
--layout_address
-- address1.xml
-- address2.xml
同样，我们希望大型应用程序有子文件夹，那么在Android项目中有办法做到这一点吗?
我能够在布局文件夹内创建layout-personal和layout_address子文件夹，但当需要使用R.layout访问XML布局文件时。_______，当时在菜单中没有任何XML布局弹出。

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
While all the proposals for multiple resource sets may work, the problem is that the current logic for the Android Studio Gradle plug-in will not update the resource files after they have changed for nested resource sets. The current implementation attempts to check the resource directories using startsWith(), so a directory structure that is nested (i.e. src/main/res/layout/layouts and src/main/res/layout/layouts_category2) will choose src/main/res/layout/layouts consistently and never actually update the changes. The end result is that you have to rebuild/clean the project each time.
我在https://android-review.googlesource.com/#/c/157971/上提交了一个补丁，试图帮助解决问题。
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']
}

我使用Android文件分组插件的Android工作室。它不允许你创建子文件夹，但是它可以显示你的文件和资源，因为它们在不同的文件夹中。这正是我想要的。
你可以安装“Android文件分组”插件通过
窗口:
Android Studio ->文件->设置->插件。
Mac:
Android Studio标签(左上)->首选项->插件->安装JetBrains插件..
对于Mac，我能够测试它，不能搜索插件。所以我从这里下载了插件，并从上面的设置中使用了从磁盘安装插件选项。
