package com.microappvalley.newtestproject;

import androidx.appcompat.app.AppCompatActivity;
import android.annotation.SuppressLint;
import android.os.Bundle;
import android.view.View;
import android.widget.CheckedTextView;


public class MainActivity extends AppCompatActivity {

    @SuppressLint("MissingInflatedId")
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        CheckedTextView checkedTextView = findViewById(R.id.checkedTextView);
        checkedTextView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // Toggle the checked state when clicked
                checkedTextView.setChecked(!checkedTextView.isChecked());

                // Perform additional actions based on the checked state
                if (checkedTextView.isChecked()) {
                    // Do something when checked
                    checkedTextView.setText("Checked!");
                } else {
                    // Do something when unchecked
                    checkedTextView.setText("Check me");
                }
            }
        });
    }
}

Open Device Manager, run the emulator, and  then run the application. Next, check the working output and check the output  you declared in your code.
