Android get String Resource Id from value

Is it possible to get the String Resource Id specified in strings.xml from the String value ?

    <string name="text1">Dummy Text</string>

I know how to get Resource Id (text1) from the String value (Dummy Text), but I want to get Resource Id (text1) from String value(Dummy Text) ? Here is how I get Dummy Text: But I want to get text1(Resource Id) from the Dummy Text value?

    context.resources.getIdentifier("text1","string",BuildConfig.APPLICATION_ID)

I think what you're looking for is the following function that uses reflection:

fun getStringResourceName(stringToSearch: String): String? {
     val fields: Array<Field> = R.string::class.java.fields
     for (field in fields) {
         val id = field.getInt(field)
         val str = resources.getString(id)
         if (str == stringToSearch) {
             return field.name
         }
    }
    return null
}

so by invoking getStringResourceName("Dummy Text") the function should return "text1".

The function can be even changed a bit to return the resource id corresponding to "Dummy Text":

fun getStringResourceId(stringToSearch: String): Int {
    val fields: Array<Field> = R.string::class.java.fields
    for (field in fields) {
        val id = field.getInt(field)
        val str = resources.getString(id)
        if (str == stringToSearch) {
            return id
        }
    }
    return -1
}

so in this case by calling getStringResourceId("Dummy Text") you can get something like 2131886277 (the latter number is just an example).
