# Alert Box in Android

##### Alert Box Description

This article consists of information about [Alert box](https://www.mindstick.com/articles/12940/how-to-create-message-alert-box-using-jquery) formation in Android. I am going to tell you how to create an Alert box pop-up window in Android and their necessary [component](https://www.mindstick.com/articles/12262/learn-how-to-make-a-component-in-magento-2) needs.

In this program, a single button is pushed against mouse to get an alert message option that provides [optional](https://www.mindstick.com/interview/22851/main-difference-between-optional-and-required-keywords) window yes or no. If you click on the popup window then yes [response](https://yourviews.mindstick.com/view/86896/biden-s-assertive-response-to-special-counsel-critique-on-memory-strength) to the [click event](https://www.mindstick.com/forum/424/how-to-call-form_paint-event-on-button-click-event). An alert box is generally used to receive a [feedback](https://www.mindstick.com/articles/12731/the-importance-of-feedback-to-the-user-experience) from the user. This feedback is generally in terms of yes or no. The component of an alert [dialog box](https://www.mindstick.com/blog/157/dialog-box-in-dot-net) is setPostiveButton and setNegativeButton value followed by [onClickListener](https://www.mindstick.com/forum/33726/inside-onclicklistener-i-cannot-access-a-lot-of-things-how-to-approach) event. onClickListener invoke when the [user clicks](https://answers.mindstick.com/qa/34556/if-a-user-clicks-all-the-google-ads-on-my-site-is-it-foul) on the button and response is generated. setPositiveButton is used to take a yes response from the user while setNegativeButton is used to provide no response on click the No text and the window is terminated. One of the most important [components](https://www.mindstick.com/blog/74096/understanding-the-role-of-some-integral-ac-components) is AlertDialog.Builder object which is used to create an alert dialog box.
