not much to do with Kotlin and Android together, but just Android, how do you organize your dimens.xml? I was thinking of having preset numbers from 10 to X, with 10 and 5 intervals in between

Those would got directly in the layout for me, because 10dp isn't different on a tablet, or in landscape mode. If you're putting

@dimen/10dp

in your layouts, then it's really the same as

10dp

. dimens.xml is more for things that will change based on configuration, like

list_margin_horizontal

or

item_title_padding_left

or

list_item_height_standard

.

You're saying that dimens.xml is useless if you only allow one configuration portrait for your app? For example?

No because there are still different sized phones. The dimensions should be set for each item, like

home_button_margin

and so then if you ever want to change your home button margin that's doable from within your styles, not in the XML files themselves

What I'm saying is that dimens.xml is useful for two things, dimensions that might change with configuration, and dimensions that are shared, like style guide elements. If you only have a single home_button, then I would hard code the

home_button_margin

. If that's used in several places throughout your app, I would make a dimen.

good points @rharter, and I agree that even if you have a

home_button_margin

you won’t be able to give it such a name as to know what this dimen refers to exactly, you’re always going to go to the XML first and see what dimension that button has, before going to dimens.xml, it’s not like your Constants file, there’s simply too many dimens to be able to name them so well that you dont even have to look at XML first
