Download android Alert, Confirm, Prompt dialog sample

A dialog is a small window that prompts the user to make a decision or enter additional information. A dialog does not fill the screen and is normally used for modal events that require users to take an action before they can proceed.

3 most used dialog window are:

• Alert dialog : We use Alert dialog to give some message to user. For example, suppose a user has started download process of a file from server, once download completed then we can use Alert dialog to inform him that Download completed successfully
• Confirm dialog : We use Confirm dialog to get user's permission before doing some critical task. For example, suppose a user has clicked on a Delete button that will delete all the app data from the device, in that case we can use Confirm dialog to get user's confirmation.
• Prompt dialog : We can use Prompt dialog if app requires some input from user at run time.
