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。
当前回答
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']
}
其他回答
答案是否定的。
我想提请您注意这本书Pro Android 2，它指出:
It is also worth noting a few constraints regarding resources. First, Android supports only a linear list of files within the predefined folders under res. For example, it does not support nested folders under the layout folder (or the other folders under res). Second, there are some similarities between the assets folder and the raw folder under res. Both folders can contain raw files, but the files within raw are considered resources and the files within assets are not. Note that because the contents of the assets folder are not considered resources, you can put an arbitrary hierarchy of folders and files within it.
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.
我只是想补充eskis对遇到麻烦的人的精彩回答。(注意:这只会工作，看起来像“项目”视图中的单独目录，不幸的是，不是“android”视图。)
用以下测试。 BuildToolsVersion = 23.0.0 Gradle 1.2.3 & 1.3.0
这就是我如何让我的工作与一个已经建立的项目。
Copy all of the XML files out of your layout directory, and put them into a directory on the desktop or something for backup. Delete the entire layout directory (Make sure you backed everything up from step 1!!!) Right click the res directory and select new > directory. Name this new directory "layouts". (This can be whatever you want, but it will not be a 'fragment' directory or 'activity' directory, that comes later). Right click the new "layouts" directory and select new > directory. (This will be the name of the type of XML files you will have in it, for example, 'fragments' and 'activities'). Right click the 'fragment' or 'activities' directory (Note: this doesn't have to be 'fragment' or 'activities' that's just what i'm using as an example) and select new > directory once again and name this directory "layout". (Note: This MUST be named 'layout'!!! very important). Put the XML files you want inside the new 'layout' directory from the backup you made on your desktop. Repeat steps 5 - 7 for as many custom directories as you desire. Once this is complete, go into your modules gradle.build file and create a sourceSets definition like this...(Make sure 'src/main/res/layouts' & 'src/main/res' are always the bottom two!!!! Like I am showing below). sourceSets { main { res.srcDirs = [ 'src/main/res/layouts/activities', 'src/main/res/layouts/fragments', 'src/main/res/layouts/content', 'src/main/res/layouts', 'src/main/res' ] } } Profit $$$$
但是说真的. .我就是这样让它起作用的。如果有人有任何问题，请告诉我。我可以试着帮忙。

现在我们可以很容易地使用JetBrains插件“Android文件分组”
看看这个链接
Android文件分组
如果你是在linux或mac上开发，一种变通方法是，创建包含符号链接到布局文件的子文件夹。只需使用ln命令和-s
ln -s PATH_TO_YOUR_FILE
问题是，你的布局文件夹仍然包含所有的.xml文件。但是你可以通过使用子文件夹来选择它们。这是最接近你想要的东西。
我刚读到，如果你使用的是Vista或更高版本，这可能也适用于Windows。这里有一个mklink命令。只是谷歌，我从来没用过。
另一个问题是，如果你已经打开了文件，并试图再次打开它，插件抛出一个空指针异常。但它并没有挂断。
