title: Set ProgressBar height
body: <p>The question seems stupid but I'm not able to simply define the height of a <code>ProgressBar</code>. Neither in code nor the xml file. The <code>layout_height</code> property seems act as the margin one, and the original size is much more smaller that I want. I have found almost nothing on the subject so I'm quite confuse. 
  The SO answer <a href="https://stackoverflow.com/questions/2739186/android-how-do-i-change-the-height-of-a-progressbar">here</a> don't works for me. And I am targeting API 15. 
  Is anybody has a solution or an explanation ? </p>
