Introduction

In Android applications, buttons are used to perform actions when the user interacts with them.

Android provides different types of buttons for different purposes:

• Button – Used to perform a specific action when clicked.
• ImageButton – A button that displays an image instead of text.
• ToggleButton – A button that switches between two states (ON/OFF).

These buttons are commonly used in applications for navigation, settings, and user interactions.

Step 1: Create a New Android Project

1. Open Android Studio
2. Click New Project
3. Select Empty Activity
4. Choose Java as the programming language
5. Click Finish

Step 2: activity_main.xml

Open res → layout → activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:padding="20dp"
    android:gravity="center">    

<!-- Normal Button -->    
<Button
        android:id="@+id/btnClick"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Click Me"/>    

<!-- Image Button -->    
<ImageButton
        android:id="@+id/imgButton"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@mipmap/ic_launcher"
        android:layout_marginTop="20dp"/>  
  
<!-- Toggle Button -->    
<ToggleButton
        android:id="@+id/toggleButton"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textOn="ON"
        android:textOff="OFF"
        android:layout_marginTop="20dp"/>
</LinearLayout>

Output

When the application runs:

• Clicking the Button displays a Toast message “Button Clicked”.
• Clicking the ImageButton displays “Image Button Clicked”.
• The ToggleButton switches between ON and OFF states and shows a Toast message accordingly.

Conclusion

In this program, we implemented three types of buttons:

• Button for performing simple click actions
• ImageButton for graphical button interaction
• ToggleButton for switching between two states

These components help create interactive and user-friendly Android applications.
