Android buttons are GUI components that are sensitive to taps (clicks) by the user. When the user taps/clicks on a button in an Android app, the app can respond to the click/tap. These buttons can be divided into two categories: the first is Buttons with text on them, and the second is buttons with an image on them. A button with images on can contain both an image and text. Android buttons with images on are also called ImageButton.
