title: Semi-transparent text box over photo
body: <p>I'm trying to overlay a semi-transparent text box over a photo for description. Tapping on the screen should make it slide up/down. It should also contain a rating bar in the bottom.</p>
  
  <p>Much like in Google Goggles <a href="http://blogote.com/wp-content/uploads/2010/10/GoogleGoggles1.jpg" rel="nofollow">http://blogote.com/wp-content/uploads/2010/10/GoogleGoggles1.jpg</a></p>
  
  <p>How would you do it? This is what I have so far:</p>
  
  <pre><code>&lt;FrameLayout 
      android:id="@+id/mainlayout" 
      android:layout_height="match_parent" 
      android:layout_width="match_parent" 
      android:orientation="vertical" 
      android:foregroundGravity="bottom"
      xmlns:android="http://schemas.android.com/apk/res/android"&gt;
  
  &lt;ImageView
      android:id="@+id/imgview" 
      android:layout_width="match_parent"
      android:layout_height="match_parent" /&gt;
  &lt;TextView 
  
      android:layout_height="wrap_content" 
      android:layout_width="match_parent" 
      android:text="@string/hello"/&gt;
  &lt;/FrameLayout&gt;
  </code></pre>
