how to convert Array[org.apache.spark.sql.Row] to Array[Int]

I'm trying to convert Array[Row] to Array[Int] but in vain. Appreciate some help

scala> res17(0).toInt
<console>:30: error: value toInt is not a member of org.apache.spark.sql.Row
          res17(0).toInt
                   ^

scala> res17(0)
res28: org.apache.spark.sql.Row = [1,0]

scala> res17(0).toArray
<console>:30: error: value toArray is not a member of org.apache.spark.sql.Row
          res17(0).toArray
                   ^

scala> res17
res30: Array[org.apache.spark.sql.Row] = Array([1,0])

Just map with getInt:

val rows: Array[Row] = ???
rows.map(_.getInt(0))
