title: Android Studio. Clickable Progress Bar
body: <p>I have created a progress bar in Android Studio that goes from 100 to 0 with a <em>step</em> 10 and <em>sleep</em>(500).Each step is displayed.</p>
  
  <p>Now what I want to do is to make the step occur whenever I click on the bar.
  How do I do this? 
  I wouldn't like to create a button on the backgroud of the progress bar, I would like to be able to click on it and make it wait for my next click.</p>
  
  <p>Thank you!</p>
