问题

I have prepared my drawables for 7" tablets as (Nexus 7)

 drawable-large-hdpi-port
 layout-large-hdpi-port

I am getting errors while doing this. I didnt understand where I am doing wrong.

I want to prepare layouts for both landscape and portrait for both 7", 10" tablets

回答1:

The recommended way is to use layout-swxxdp qualifier. If you need to differentiate landscape/portrait

res/layout-sw600dp/   # For 7” tablets (600dp wide and bigger)
res/layout-sw720dp/   # For 10” tablets (720dp wide and bigger)
res/layout-sw600dp-port/   # For 7” tablets in portrait (600dp wide or bigger)
res/layout-sw720dp-port/  # For 10” tablets in portrait (720dp wide or bigger)

You are naming the folders in the wrong way. In Android, there is a rule or order in which you name your resource folders. You should provide your qualifier names in that order.

Check this documentation table on providing resources. Your should name your folders in the order provided in the table.(Its better if you read the whole page, because it'll give you a better understanding in providing resources)

Here you should name the folders as

layout-large-port-hdpi
drawable-large-port-hdpi

For preparing the resource folders for tablets, you can use either the screen size attribute or shortest width attribute.

For e.g

If you use screen size attribute, you can name folders like

layout-large-... (for 7" devices)
layout-xlarge-... (for 10" devices)

I you use shortest width attribute, you can use

layout-sw600dp-... (for 7" devices)
layout-sw720dp-... (for 10" devices)

Remember shortest width attribute works only on devices from 3.2 (API 13).
