如果我能理解您的问题，那不是不可以，但是例如在xlarge设备上，您的应用程序随附有layout-xlarge用于布局，xhdpi用于可绘制。

Please make your layout using different values folder in resource. And make only one or two layout for portrait and landscape layouts. Also make different drawable folder for different size of images.

Android Studio will choose the suitable dpi for you. So you can put every image you have used in each folder your created in different size but same name. for example:

0.75x drawable-ldpi   (120 dpi, Low density screen)        - 36 x 36px<br/> 
1x    drawable-mdpi   (160 dpi, Medium density screen)     - 48 x 48px<br/> 
1.5x  drawable-hdpi   (240 dpi, High density screen)       - 72 x 72px<br/> 
2x    drawable-xhdpi  (320 dpi, Extra-high density screen) - 96 x 96px<br/> 
3x    drawable-xxhdpi (480 dpi,                         )  - 144 x 144px
