Question

From a user-interface perspective, why is there a title option to an AlertDialog? Why doesn’t the message alone suffice? Do we really need a title? If so, please provide visual examples of where a title would be useful.

The AlertDialog documentation shows an AlertDialog without a title, and it looks perfect to me:

Answer 1

The Android Design guide on Alerts says:

Alerts

Alerts inform the user about a situation that requires their
confirmation or acknowledgement before proceeding. They differ
slightly in appearance based upon the severity and impact of the
message conveyed.

Alerts without title bars

Most alerts don’t need titles. Usually the decision doesn’t have a
severe impact and can be summed up succinctly in a sentence or two.
The content area should either ask a question (such as “Delete this
conversation?”) or make a clear statement whose relationship to the
action buttons is obvious.

Alerts with title bars

Keep the question or statement short: for example, “Erase USB
storage?” Avoid apologies. A user should be able to skip the content
completely and still have a clear idea of what choices are available
based on the title and the text of the action buttons.

When crafting a confirmation dialog, make the title meaningful by
echoing the requested action.

Don’t:

• Are you sure?
• Don’t
• Warning!

Do:

• Erase USB storage?
