I want to design a application for different tablets so i created different layout folders i.e.

  • layout-sw600dp
  • layout-sw720dp

Now the problem is that i am testing the application in 2 tabs having 1280x800 & 2048x1536 resolutions respectively and they both fall under layout-sw720dp folder only. So how can i differentiate between both of them so that i can draw layouts separately.

Or i just need to get the pixel density and calculate for each and everything to design for these tabs like this :

dp = px / (dpi / 160)

Please refer to this DOCUMENTATION and also this link

+----------------+----------------+---------------+-------------------------------+
| Density Bucket | Screen Density | Physical Size | Pixel Size                    | 
+----------------+----------------+---------------+-------------------------------+
| ldpi           | 120 dpi        | 0.5 x 0.5 in  | 0.5 in * 120 dpi = 60x60 px   | 
+----------------+----------------+---------------+-------------------------------+
| mdpi           | 160 dpi        | 0.5 x 0.5 in  | 0.5 in * 160 dpi = 80x80 px   | 
+----------------+----------------+---------------+-------------------------------+
| hdpi           | 240 dpi        | 0.5 x 0.5 in  | 0.5 in * 240 dpi = 120x120 px | 
+----------------+----------------+---------------+-------------------------------+
| xhdpi          | 320 dpi        | 0.5 x 0.5 in  | 0.5 in * 320 dpi = 160x160 px | 
+----------------+----------------+---------------+-------------------------------+
| xxhdpi         | 480 dpi        | 0.5 x 0.5 in  | 0.5 in * 480 dpi = 240x240 px | 
+----------------+----------------+---------------+-------------------------------+
| xxxhdpi        | 640 dpi        | 0.5 x 0.5 in  | 0.5 in * 640 dpi = 320x320 px |

If layouts are problem then why don't you try using SPD library for margin padding dimens.

Using this you may have to make only one layout for all screen sizes

  • i know i can do it by calculating the pixel density thats what i am asking that the only way i can do it is by calculating that for each view only or i can somehow make a different layout separately for both. – Anmol317 Apr 16 '18 at 11:17
