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

If you just want to change the size font dynamically then you can:

textView.setTextSize(TypedValue.COMPLEX_UNIT_PX, resources.getDimension(R.dimen.tutorial_cross_marginTop))

As @achie's answer, you can get the dp from dimens.xml like this:

val dpValue = (resources.getDimension(R.dimen.tutorial_cross_marginTop)/ resources.displayMetrics.density).toInt()

or get sp like this

val spValue = (resources.getDimension(R.dimen.font_size)/ resources.displayMetrics.scaledDensity).toInt()

About Resources.java #{getDimension}

    /**
     * Retrieve a dimensional for a particular resource ID.  Unit 
     * conversions are based on the current {@link DisplayMetrics} associated
     * with the resources.
     * 
     * @param id The desired resource identifier, as generated by the aapt
     *           tool. This integer encodes the package, type, and resource
     *           entry. The value 0 is an invalid identifier.
     * 
     * @return Resource dimension value multiplied by the appropriate 
     * metric.
     * 
     * @throws NotFoundException Throws NotFoundException if the given ID does not exist.
     *

     * @see #getDimensionPixelSize

Resource dimension value multiplied by the appropriate
