提问by Paresh Mayani
I was working on Android 1.5, but I have now moved to the latest version. So there is only one "drawable" folder in Android 1.5, but now there are three different folders for storing images in the Android project.
我在 Android 1.5 上工作，但我现在已经转移到最新版本。所以在Android 1.5中只有一个“drawable”文件夹，但现在Android项目中有三个不同的文件夹用于存储图像。
And I have found some articles for these three folders that says
我发现这三个文件夹的一些文章说
- hdpi means High-dpi
- mdpi means medium-dpi
- ldpi means low-dpi
- hdpi 表示高 dpi
- mdpi 表示中等 dpi
- ldpi 表示低 dpi
But what is the exact purpose of these three folders and when should I use a particular folder to store images in?
但是这三个文件夹的确切用途是什么，我什么时候应该使用特定的文件夹来存储图像？

To declare different layouts and bitmaps you'd like to use for the different screens, you must place these alternative resources in separate directories/folders.
要声明要用于不同屏幕的不同布局和位图，您必须将这些替代资源放在不同的目录/文件夹中。
This means that if you generate a 200x200image for xhdpidevices, you should generate the same resource in 150x150for hdpi, 100x100for mdpi, and 75x75for ldpidevices.
这意味着如果您200x200为xhdpi设备生成图像，您应该在150x150for hdpi、100x100formdpi和75x75for ldpidevices 中生成相同的资源。
Then, place the files in the appropriate drawable resource directory:
然后，将文件放在适当的可绘制资源目录中：
MyProject/
res/
drawable-xhdpi/
awesomeimage.png
drawable-hdpi/
awesomeimage.png
drawable-mdpi/
awesomeimage.png
drawable-ldpi/
awesomeimage.png
Any time you reference @drawable/awesomeimage, the system selects the appropriate bitmap based on the screen's density.
每当您引用 时@drawable/awesomeimage，系统都会根据屏幕的密度选择适当的位图。
