<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"

    <CheckBox
        android:id="@+id/checkBox22"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"

        app:layout_constraintTop_toBottomOf="@+id/textView23" />

    <TextView
        android:id="@+id/textView23"

MainActivity.java

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.widget.CheckBox;
import android.widget.CompoundButton;
import android.widget.Toast;


public class CheckBox9 extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_check_box9);

        CheckBox checkBox = findViewById(R.id.checkBox22);
        checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                //This will prevent the Checkbox from changing state
                buttonView.setChecked(false);
                Toast.makeText(getApplicationContext(), "The state cannot be change", Toast.LENGTH_SHORT).show();
