现在有了Android Studio和Gradle，你可以在你的项目中有多个资源文件夹。允许组织不仅你的布局文件，但任何类型的资源。

它不是一个确切的子文件夹，但可以分离应用程序的部分。

配置如下:

sourceSets {
    main {
        res.srcDirs = ['src/main/res', 'src/main/res2']
    }
}

检查文档。

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。

图片比文字更有价值。

第一步:在资源管理器中右键单击布局-显示 步骤2:打开布局文件夹并直接创建子文件夹:layout_1, layout_2… 步骤3:打开layout_1创建文件夹布局(注意:必选名称为布局)，打开layout_2文件夹创建文件夹布局子目录(注意:必选名称为布局)… 步骤4:将xml文件复制到layout_1和layout_2的布局子目录中 步骤5:运行build中的代码。Grade(模块应用)，现在点击同步:

sourceSets {
    main {
        res.srcDirs =
            [
                'src / main / res / layout / layout_1'
                'src / main / res / layout / layout_2',
                'src / main / res'
            ]
    }
}

第6步:总结:以上所有步骤将只帮助集群文件夹和显示在“项目”模式，而“android”模式将正常显示。 所以我认为命名前缀可能和集群文件夹一样有效。

顶部答案有几个缺点:你必须添加新的布局路径，AS将新的资源放在res\layouts文件夹而不是res\values。

结合几个答案，我写下了类似的内容:

sourceSets {
    main {
        res.srcDirs =
                [
                        'src/main/res',
                        file("src/main/res/layouts/").listFiles(),
                        'src/main/res/layouts'
                ]
    }
}

我用这篇文章做了文件夹:http://alexzh.com/tutorials/how-to-store-layouts-in-different-folders-in-android-project/。为了创建子文件夹，你应该使用这个菜单:新建>文件夹> Res文件夹。

更新

几周后，我发现Android Studio并没有注意到资源的变化。于是，一些奇怪的虫子出现了。例如，布局仍然显示旧的尺寸和页边距。有时AS找不到新的xml文件(特别是在运行时)。有时它混合了视图id(对另一个xml文件的引用)。通常需要按Build > Clean Project或Build > Rebuild Project。在Android Studio中更改xml布局文件后，阅读需要重新构建的文件。

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.
