Question

Explain about the dialog boxes supported on Android?

Answer 1

Android supports four dialog boxes. They are:

• AlertDialog:
  • The AlertDialog supports 0-3 buttons, along with a list of selectable items such as checkboxes and radio buttons.
  • It is used when you want to ask the user about taking a decision between yes or no in response to any particular action taken by the user, by remaining in the same activity and without changing the screen.
• DatePickerDialog:
  • It is used for selecting the date by the user.
• TimePickerDialog:
  • Used for selecting the time by the user.
• ProgressDialog:
  • It is an extension of the AlertDialog and is used to display a progress bar. It also supports the addition of buttons.
  • This class was deprecated in API level 26 because it prevents the user from interacting with the application. Instead of this class, we can use a progress indicator such as ProgressBar, which can be embedded in the user interface of your application.
