How to create a transparent activity WITHOUT windowIsFloating

Question

windowIsFloating while a great one stop shop for creating Dialog styled UI's has many ---bugs--- quirks.

The one which I'm battling right now is that it assigned the width/height of the top ancestor as "wrap_content" rather than the width/height of the screen. This means the usual UI design of using "match_parents" will propogate upwards to become "wrap_content". Bad times.

So, what I would really like is to create an activity, and have a layout like so:

<LinearLayout   android:layout_height="wrap_content"
                android:layout_width="match_parent"
                android:orientation="vertical"
                android:id="@+id/containerPageConatiner"
                android:background="@drawable/windowBackground">
    <View           android:layout_width="match_parent"
                    android:layout_height="0dp"
                    android:layout_weight="1"/>
    <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"/>    
    <View           android:layout_width="match_parent"
                    android:layout_height="0dp"
                    android:layout_weight="1"/>                         
</LinearLayout> 

Which produces a UI showing a single window (@id/singlePane) ontop of the Activity which called it.

Does anybody have the just right set of styles needed to create a transparent background Activity?

Thanks to @PolamReddy who nudged me towards answer I wanted:

The theme Theme.Translucent.NoTitleBar.Fullscreen and its ancestors contains all the attributes you need to create a translucent window. In order to get everything apart from windowIsFloating I went through the ancestor stack and pulled out the entire set of attributes:

<style name="Theme.CustomTheme.TransparentActivity">
    <item name="android:windowBackground">@android:color/transparent</item>
    <item name="android:colorBackgroundCacheHint">@null</item>
    <item name="android:windowIsTranslucent">true</item>
    <item name="android:windowAnimationStyle">@android:style/Animation</item>
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowContentOverlay">@null</item>
    <item name="android:windowFullscreen">true</item>
</style> 

This style must be assigned to the Activity in the AndroidManifest.xml rather than the root view of a layout.
