Toast in Android is a simple message box.

When the view is displayed to the user, it is displayed as floating in the application. Unlike Dialog, it never gets focus and can't be clicked on. The user will probably type something else in the middle. The idea of the Toast class is to go as unnoticed as possible, while also displaying information to users in the hope that they will see it. And Toast display time is limited, Toast will automatically disappear according to the display time set by the user.
