 <style name="NoBorderDialog" parent="@android:style/Theme.Dialog">        <item name="android:windowFrame">@null</item>        <item name="android:windowIsFloating">true</item>        <item name="android:windowIsTranslucent">false</item>        <item name="android:windowNoTitle">true</item>        <item name="android:background">@android:color/black</item>        <item name="android:windowBackground">@null</item>        <item name="android:backgroundDimEnabled">false</item> </style>
