Android can't change height of constraint layout in post
I am trying to change the height of the ContraintLayout inside the post block.
like so:
class MainActivity : AppCompatActivity() {

override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
changeHeight()
}

private fun changeHeight() {
val layoutView = findViewById(R.id.block1)
layoutView?.post {
Log.d("222", "1===========")
layoutView.run {...
