Simple and plain buttons can do the job triggering some events in Android. But if you want to add more flavor and design to your UI, you can customize your buttons. Customization may include adding an image for your button, changing its image when pressed and/or displaying another image if it is focused.
In this section, we will create a simple customized button.
