Android Button Control

Android Button control represents a push-button that can be pressed, or clicked to perform an action. Generally, while using an app, we see many buttons and being a user to initiate an action, we click one at a time.


Button can be an OK, Submit, or any other that initiates an action. For example, in the below figure 4 buttons are visible.
