Toast message

This is one of the common practices to pop-up a message box for notifying the user. This kind of notification is a type of notification that does not require a user answer or feedback.

Toast.makeText(this.getApplicationContext(), hellomsg,
         Toast.LENGTH_SHORT).show();

Toast.makeText() contains three parameters which are the application context, the message and the time length.

  • The application context is the current screen to display the message
  • The message is the string to be displayed
  • The time length is consisting of a short or longer duration of the message display and has to be one of Toast.LENGTH_* constants
