Add the Button element to the layout:
Step 2: Set Up Button in Java/Kotlin Code
In your Activity file (e.g., MainActivity.java or MainActivity.kt), you can reference the Button and set an OnClickListener to handle click events.
Step 3: Run Your Application
Ensure your Android device or emulator is set up.
Run your application.
Click the button to see the action performed (e.g., a Toast message displayed).

Changing Background Color:
android:background="@color/your_color"
Setting Padding:
android:padding="16dp"
