我这样做的一种方式是在你的项目中创建一个与实际res文件夹相同级别的单独的res文件夹，然后你可以在你的应用程序build.gradle中使用这个

android {
    //other stuff

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

然后每个新res文件夹的子文件夹可以一些有关每个特定屏幕或一些在你的应用程序,和每个文件夹都有自己的布局/可拉的价值观等保持事物的组织和你不必须手动更新gradle文件和其他一些答案要求(同步你gradle每次添加一个新的资源文件夹,所以它知道它,并确保添加相关的子文件夹之前添加xml文件)。

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。

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

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。

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.
