title: Progress bar base on right answer
body: <p>I create a simple math game and I would like to update my progress bar base on the right question answer.
  Examples: every time I answer correctly to a question the progress bar should go bu 10% and so on.     </p>
  
  <pre><code>public class QuestionActivity extends Activity

      Button button1, button2, button3;
      ProgressBar pb;
