Array of buttons in Kotlin

Question

How can I create array of buttons in android studio in Kotlin? I've created buttons with their ids in a xml file, now I want to use the same buttons in my Kotlin code as array's elements. I've tried something like this: var buttons: Array = Array(25) and then: buttons[0] = btn1 // btn1 as the id from xml file However button names from xml don't work in kotlin file, how can I use them?

Supposed you have a layout like this: <?xml version="1.0" encoding="utf-8"?> First, apply kotlin extensions plugin for syntetic syntax in your build.gradle with apply plugin: 'kotlin-android-extensions' Then, you can simply initalize an array of buttons in your code by doing: val buttons = arrayOf(btOne, btTwo, btThree) Otherwise, if you don't want to use kotlin syntetic, simply use the old findviewbyid syntax val buttons = arrayOf( findViewById(R.id.btOne), findViewById(R.id.btTwo), findViewById(R.id.btThree) )
