dimen 를 활용한 모든 기기 화면 최적화

dimen 태그로 dp 값을 저장하여, 해당 값을 pixel로 손쉽게 불러올 수 있다

• values 하위 dimen.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <dimen name="edit_detail_padding">44dp</dimen>
    <dimen name="edit_detail_focus_padding">16dp</dimen>
</resources>

• kotlin 에서 활용

val newPadding = resources.getDimensionPixelSize(R.dimen.edit_detail_padding)
val oldPadding = resources.getDimensionPixelSize(R.dimen.edit_detail_focus_padding)

editAlcohol.setOnFocusChangeListener { v, hasFocus ->
    if (hasFocus) {
        editAlcohol.setPadding(newPadding, oldPadding, oldPadding, oldPadding)
        editAlcohol.setBackgroundResource(R.drawable.rect_darkgray2fill_graystroke_14radius)
        deleteBtn.visibility = View.INVISIBLE
        eraseBtn.visibility = View.VISIBLE
    } else {
        editAlcohol.setPadding(oldPadding, oldPadding, oldPadding, oldPadding)
        editAlcohol.setBackgroundResource(R.drawable.rect_darkgrayfill_graystroke_14radius)
        deleteBtn.visibility = View.VISIBLE
        eraseBtn.visibility = View.INVISIBLE
    }
}
