I'm attempting to create a custom dialog with a semi transparent background. I managed to get it to work through code with:\[code\]getWindow().setBackgroundDrawableResource(R.color.bg_tran);\[/code\]Where bg_tran == #A0000000. However I'd rather have it in XML as I use this for several different custom dialog classes. Using just android:background does not work. Nor setting the theme to @android:style/Theme.Translucent worked.I found several articles talking about using the attribute android:windowBackground. However the android:windowBackground attribute does not exist. Meaning eclipse doesn't show me it as an option for auto complete. I've checked within my style sheet and my actual layout.xml. Since I'm compiling for 2.2 I thought that the issue and changed build target to 4.0.3. No fix. I've even tried explicitly using it anyway but it doesn't work. I searched the Android Dev website and can't even find the page which describes this attribute. Aside from occasionally mentioning in passing, there's nothing. Also looking up setBackgroundDrawableResource doesn't tell me what the equivalent XML attribute tag is. I'm incredibly confused. What am I missing?Stack overflow references I used to learn above:

Update:
In case it wasn't clear, yes I've tried setting this up within a theme. Does not work. Here's my defined theme:\[code\]<style name="my_dialog_theme" parent="@android:style/Theme.Dialog"> <item name="android:windowBackground">@color/bg_tran</item> <item name="android:windowIsTranslucent">true</item> <item name="android:layout_height">wrap_content</item> <item name="android:layout_width">wrap_content</item></style>\[/code\]
