Load dimension value from res/values/dimension.xml from source code

Question

I\'d like to load the value as it is. I have two dimension.xml files, one in /res/values/dimension.xml and the other one in /res/values-sw360

Answer 1

In my dimens.xml I have

48dp

In code If I do

int valueInPixels = (int) getResources().getDimension(R.dimen.test)

this will return 72 which as docs state is multiplied by density of current phone (48dp x 1.5 in my case)

exactly as docs state :

Retrieve a dimensional for a particular resource ID. Unit conversions are based on the current DisplayMetrics associated with the resources.

so if you want exact dp value just as in xml just divide it with DisplayMetrics density

int dp = (int) (getResources().getDimension(R.dimen.test) / getResources().getDisplayMetrics().density)

dp will be 48 now
