  <p>I want to make transparent the <strong>transparent_layout</strong> but i can't do it.</p>
  
  <p>Already tried settings the background programmatically with the color: Color.TRANSPARENT but it seems it doesnt work.</p>
  
  <p>Im using Android 2.3.3 SDK with SherlockActionBar.</p>
  
  <p>Is there any way to set that layout to transparent?</p>
