Android ToggleButton

In Android Studio, you can create  toggle buttons using the ToggleButton widget.

Here is the tutorial for Kotlin

Here's a simple example to help you understand how to implement  toggle buttons in Android Studio :

Step 1 :

File open res/layout/activity_main.xml file :

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:gravity="center"
        android:layout_margin="20dp"
        android:orientation="vertical">

        <!--set Checked -->
        <ToggleButton
            android:id="@+id/toggleButton1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:checked="true"
            android:text="ToggleButton" />

       <!-- set Text Name-->
        <ToggleButton
            android:id="@+id/toggleButton2"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textOn="Enable"
            android:textOff="Disible"
            android:text="ToggleButton" />

        <Button
            android:id="@+id/buttonSubmit"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="Submit" />
    </LinearLayout>

</RelativeLayout>

Step 2 :

File open com.microappvalley.newtestproject/MainActivity.java file −

Java

package com.microappvalley.newtestproject;

import androidx.appcompat.app.AppCompatActivity;

import android.annotation.SuppressLint;
import android.graphics.Color;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.CompoundButton;
import android.widget.Toast;
import android.widget.ToggleButton;

public class MainActivity extends AppCompatActivity {
    ToggleButton toggleButton1;
    ToggleButton toggleButton2;
    Button buttonSubmit;
    @SuppressLint("MissingInflatedId")
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        toggleButton1=(ToggleButton) findViewById(R.id.toggleButton1);
        toggleButton2=(ToggleButton) findViewById(R.id.toggleButton2);

        buttonSubmit=(Button) findViewById(R.id.buttonSubmit);
        toggleButton1.setChecked(true); //toggleButton ON
        toggleButton1.setTextColor(Color.YELLOW);

        toggleButton1.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                if (isChecked) {
                    // Handle toggle button ON state
                    Toast.makeText(MainActivity.this, "Toggle Button ON", Toast.LENGTH_SHORT).show();
                } else {
                    // Handle toggle button OFF state
                    Toast.makeText(MainActivity.this, "Toggle Button OFF", Toast.LENGTH_SHORT).show();
                }
            }
        });

        buttonSubmit.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                String switchData=toggleButton1.getText().toString()+ "\n"+toggleButton2.getText().toString();

                Toast.makeText(MainActivity.this, switchData, Toast.LENGTH_SHORT).show();
            }
        });


    }
}

Kotlin:

package com.microappvalley.newtestproject

import android.os.Bundle
import android.widget.Button
import android.widget.Toast
import android.widget.ToggleButton
import androidx.appcompat.app.AppCompatActivity

class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        val toggleButton1: ToggleButton = findViewById(R.id.toggleButton1)
        val toggleButton2: ToggleButton = findViewById(R.id.toggleButton2)
        val buttonSubmit: Button = findViewById(R.id.buttonSubmit)
        toggleButton1.setOnCheckedChangeListener { buttonView, isChecked ->
            if (isChecked) {
                // Handle toggle button ON state
                Toast.makeText(this@MainActivity, "Toggle Button ON", Toast.LENGTH_SHORT).show()
            } else {
                // Handle toggle button OFF state
                Toast.makeText(this@MainActivity, "Toggle Button OFF", Toast.LENGTH_SHORT).show()
            }
        }

        buttonSubmit.setOnClickListener() {
            val switchData = "${toggleButton1.text} \n ${toggleButton2.text}"

            Toast.makeText(this@MainActivity, switchData, Toast.LENGTH_SHORT).show()
        }
    }
}

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.
