How to lock ImageView orientation in Activity?

How to lock ImageView orientation when rotate screen in Kotlin? simply how to freeze ImageView (as background) when rotate activity?

Trying: I tried to change a image in LinearLayout as background, and use this method but it is not working!!

override fun onConfigurationChanged(newConfig : Configuration) {
    super.onConfigurationChanged(newConfig)
    val linearLayout = findViewById<LinearLayout>(R.id.linearBg)
    if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
        linearLayout.setBackgroundResource(R.drawable.bg_landscape)
    } else if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT) {
        linearLayout.setBackgroundResource(R.drawable.bg_portrait)
    }
}
Solution 
  • val screenOrientation = this.resources.configuration.orientation
    if (screenOrientation == Configuration.ORIENTATION_PORTRAIT) {
        // TODO
    } else {
        // TODO
    }
