Android, getting resource ID from string?

Question

I need to pass a resource ID to a method in one of my classes. It needs to use both the id that the reference points to and also it needs the string. How should I best achie

Answer 1

The Kotlin approach

inline fun > T.getId(resourceName: String): Int {
            return try {
                val idField = getDeclaredField (resourceName)
                idField.getInt(idField)
            } catch (e:Exception) {
                e.printStackTrace()
                -1
            }
        }

Usage:

val resId = R.drawable::class.java.getId("icon")
