androidx.gridlayout.widget.GridLayout cannot be cast to android.widget.GridLayout

Question

I am getting error

"Caused by: java.lang.ClassCastException: androidx.gridlayout.widget.GridLayout cannot be cast to android.widget.GridLayout", in mainActivity.java

 GridLayout mygridLayout = findViewById(R.id.gridLayout);

 for(int i=0; i<mygridLayout.getChildCount(); i++)
 {
     ((ImageView) mygridLayout.getChildAt(i)).setImageResource(0);
