title: How to create a transparent activity WITHOUT windowIsFloating
body: <p><code>windowIsFloating</code> while a great one stop shop for creating <code>Dialog</code> styled UI's has many 
  ---bugs--- quirks.</p>
  
  <p>The one which I'm battling right now is that it assigned the width/height of the top ancestor as <code>"wrap_content</code>" rather than the width/height of the screen. This means the usual UI design of using <code>"match_parents"</code> will propogate upwards to become <code>"wrap_content"</code>. Bad times.</p>
  
  <p>So, what I would really like is to create an activity, and have a layout like so:</p>
  
  <pre><code>&lt;LinearLayout   android:layout_height="wrap_content"
                  android:layout_width="match_parent"
                  android:orientation="vertical"
                  android:id="@+id/containerPageConatiner"
                  android:background="@drawable/windowBackground"&gt;
      &lt;View           android:layout_width="match_parent"
                      android:layout_height="0dp"
                      android:layout_weight="1"/&gt;
      &lt;FrameLayout    android:id="@+id/singlePane"
                      android:layout_height="wrap_content"
                      android:layout_width="match_parent"
                      android:layout_gravity="center_horizontal|center_vertical"
                      android:padding="10dp"/&gt;    
      &lt;View           android:layout_width="match_parent"
                      android:layout_height="0dp"
                      android:layout_weight="1"/&gt;                         
  &lt;/LinearLayout&gt; 
  </code></pre>
  
  <p>Which produces a UI showing a single window (@id/singlePane) ontop of the Activity which called it. </p>
  
  <p>Does anybody have the <em>just right</em> set of styles needed to create a transparent background Activity?</p>
