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。

    }
}

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。

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。

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.

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.
