First, the usage of the Alert Dialog. Alert Dialogs are simple and lightweight tools for displaying some “alert” or simple message, like “are you sure you want to exit this application, or deleting something or showing successful operation by the user with interaction. It can have custom positive and negative buttons for interaction, like “OK” and “Cancel”, “Wait”, “Done” or something like that, by your choice for what you want the alert dialog to do.
