The Android API supports the following types of Dialog objects:

AlertDialog 알림

A dialog that can manage zero, one, two, or three buttons, and/or a list of selectable items that can include checkboxes or radio buttons. The AlertDialog is capable of constructing most dialog user interfaces and is the suggested dialog type. See Creating an AlertDialog below.

ProgressDialog

A dialog that displays a progress wheel or progress bar. Because it's an extension of the AlertDialog, it also supports buttons. See Creating a ProgressDialog below.

DatePickerDialog 날짜 선택

A dialog that allows the user to select a date. See the Hello DatePicker tutorial.

TimePickerDialog 시간 선택

A dialog that allows the user to select a time. See the Hello TimePicker tutorial.

If you would like to customize your own dialog, you can extend the base Dialog object or any of the subclasses listed above and define a new layout. See the section on Creating a Custom Dialog below.
