First, we need to drag two toggle buttons and one button for the layout. The code of the activity_main.xml file will be then:

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
   xmlns:app="http://schemas.android.com/apk/res-auto"
   android:layout_width="match_parent"
   android:layout_height="match_parent"
 >
 
   <ToggleButton
       android:id="@+id/toggleButton"
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:layout_marginLeft="8dp"
       android:layout_marginTop="80dp"
       android:text="ToggleButton"
       android:textOff="Off"
       android:textOn="On"
       app:layout_constraintEnd_toStartOf="@+id/toggleButton2"
       app:layout_constraintStart_toStartOf="parent"
       app:layout_constraintTop_toTopOf="parent" />
 
   <ToggleButton
       android:id="@+id/toggleButton2"
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:layout_marginRight="60dp"
       android:layout_marginTop="80dp"
       android:text="ToggleButton"
       android:textOff="Off"
       android:textOn="On"
       app:layout_constraintEnd_toEndOf="parent"
       app:layout_constraintTop_toTopOf="parent" />
 
   <Button
       android:id="@+id/button"
      android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:layout_marginBottom="144dp"
       android:layout_marginLeft="148dp"
       android:text="Submit"
       app:layout_constraintBottom_toBottomOf="parent"
       app:layout_constraintStart_toStartOf="parent" />
</android.support.constraint.ConstraintLayout>

Activity class:

Code to check if toggle button is ON/OFF:

package com.example.app1;
 
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;
import android.widget.ToggleButton;
 
public class MainActivity extends AppCompatActivity {
   private ToggleButton toggleButton1, toggleButton2;
   private Button buttonSubmit;
   @Override
   protected void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.activity_main);
 
       addListenerOnButtonClick();
   }
 
   public void addListenerOnButtonClick(){
       //Getting the ToggleButton and Button instance from the layout xml file
       toggleButton1= findViewById(R.id.toggleButton);
       toggleButton2= findViewById(R.id.toggleButton2);
       buttonSubmit= findViewById(R.id.button);
 
       //Performing action on button click
       buttonSubmit.setOnClickListener(new View.OnClickListener(){
 
           @Override
           public void onClick(View view) {
               StringBuilder result = new StringBuilder();
               result.append("ToggleButton1 : ").append(toggleButton1.getText());
               result.append("\nToggleButton2 : ").append(toggleButton2.getText());
               //Displaying the message in toast
               Toast.makeText(getApplicationContext(), result.toString(),Toast.LENGTH_LONG).show();
           }
 
       });
