title: Setting the holographic theme in Honeycomb
body: <p>I saw this post about using the new holographic themes on Honeycomb:
  <a href="https://stackoverflow.com/questions/4865724/change-theme-according-to-android-version">Change theme according to android version</a></p>
  
  <p>In my app, I have minSdkVersion="11" and targetSdkVersion="11". By default, I get a solid black background with light text. If I explicitly set Theme.Holo, on either application or activity, I still get the solid black, using this:</p>
  
  <p>android:theme="@android:style/Theme.Holo"</p>
  
  <p>However, I think Theme.Holo uses the gradient background I see in the HoneycombGallery example, set like this:</p>
  
  <pre><code>  case R.id.toggleTheme:
         if (mThemeId == android.R.style.Theme_Holo) {
              mThemeId = android.R.style.Theme_Holo_Light;
         } else {
              mThemeId = android.R.style.Theme_Holo;
    }
  </code></pre>
  
  <p>If that's the real holographic theme, how do I get it?</p>
