Androidx.gridlayout.widget.GridLayout Cannot Be Cast To Android.widget.GridLayout

I am getting error 'Caused by: java.lang.ClassCastException: androidx.gridlayout.widget.GridLayout cannot be cast to android.widget.GridLayout', in mainActivity.java GridLa

Solution 1:

Change

import android.widget.gridLayout 

to

import androidx.gridlayout.widget.GridLayout;

and your code will work

Solution 2:

Use this in the code it will work.

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

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

Solution 3:

You are using GridLayout from AndroidX package in your layout.xml and you are importing Gridlayout from package android.widget in your source code. Use one or the other and make them consistent.

Solution 4:

You should change your code to this:

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

Solution 5:

For this, we need to import "androidx.gridlayout.widget.GridLayout;" instead of "android.widget.GridLayout;".
