# Android  Rating bar

Rating bar is a control which provides a [user interface](https://www.mindstick.com/blog/302016/what-is-user-interface-and-what-are-its-benefits) to give feedback about the [application](https://www.mindstick.com/articles/12824/calculator-application-in-android). It always returns value in floating point. I am using Rating Bar, Button and [Text view](https://www.mindstick.com/forum/33384/detail-text-view-of-cell-not-showing) controls to get the feedback 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. ratingbar() and [onClickListener](https://www.mindstick.com/forum/33726/inside-onclicklistener-i-cannot-access-a-lot-of-things-how-to-approach) are used to invoke the users' feedback.

**o android:numStars:** This [attribute](https://www.mindstick.com/blog/61/ado-dot-net-object-model-and-attributes) displays the number of stars for user feedback

**o android:rating****:** By this method, you can set rating point for the user

**o android:isIndicator:** It checks whether rating bar has indicator state
