App crashing in the part of Grid layout declaration

Class & XML are not the same

public void r(View view)
        {
            LinearLayout linearLayout=findViewById(R.id.playAgain);
            linearLayout.setVisibility(View.INVISIBLE);

            activePLayer=0 ;

            for(int i=0;i<9;i++)
            {
                gameState[i]=2;
            }

            Log.i("Success","0");
//Till this part it's working

            GridLayout gridL = findViewById(R.id.gl);
            Log.i("Success","0");
//This log don't show up

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

        }

I want to reset my Connect-3 game made in a constraint layout to play it again but my app crashes at the point of declaration of GridLayout. Any suggestions ?

My build error log :-

Change from

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

to

androidx.gridlayout.widget.GridLayout gridLayout = findViewById(R.id.gridLayout);

it is written in your stack trace,

java.lang.ClassCastException: android.support.v7.widget.GridLayout cannot be cast to android.widget.GridLayout

your Class & XML are not the same. You need to make sure that the import is correct

to fix this, just switch the current import with:

import android.support.v7.widget.GridLayout;
