Be sure to create your Dialog referencing your custom theme:

Dialog dialog = new Dialog(this, R.style.MyDialogTheme); 

Your custom theme needs to fill the screen and disable a couple of Android framework defaults:

<?xml version="1.0" encoding="utf-8"?> <resources>     <style name="MyDialogTheme" parent="android:Theme.Dialog">         <!-- Fill the screen -->         <item name="android:layout_width">fill_parent</item>         <item name="android:layout_height">fill_parent</item>          <!-- No backgrounds, titles or window float -->         <item name="android:windowBackground">@null</item>         <item name="android:windowNoTitle">true</item>         <item name="android:windowIsFloating">false</item>                <!-- Just to prove it's working -->         <item name="android:background">#ff0000</item>     </style>  </resources>
