Android Custom PopupWindow/Dialog

Question

I'm trying to get a completely custom Dialog or PopupWindow, without any of the default Android UI controls (title, background, buttons, whatever).

Is this possible at all? I've spent hours searching for this, but no luck... It seems like this should be easily possible, but I can't find it.

Preferably this would be by inflating a View from XML, but at this point anything that would just work would be nice.

Thanks.

Steps I took:

1. Create a class extending Dialog.
2. In the onCreate, call setContentView(x, y) with x being your R.layout and y being R.style.popupStyle (see below).
3. In your res/values/style.xml, you need to override the default DialogWindow style. I tried just making a style that has this one as its parent, but that still didn't clear all defaults. So I checked the Android git tree and got the default style, and just copy-pasted it. This is the one:

<style name="Theme.Dialog">
    <item name="android:windowFrame">@null</item>
    <item name="android:windowTitleStyle">@android:style/DialogWindowTitle</item>
    <item name="android:windowBackground">@android:drawable/panel_background</item>
    <item name="android:windowIsFloating">true</item>
    <item name="android:windowContentOverlay">@null</item>
    <item name="android:windowAnimationStyle">@android:style/Animation.Dialog</item>
    <item name="android:windowSoftInputMode">stateUnspecified|adjustPan</item>
</style>

You'll get a few errors, just solve them by copying more stuff from the official Android styles.xml and themes.xml files. Here's the contents of my styles.xml file: http://pastebin.com/RRR15YYS

That just gives you a white popup, no borders, nothing. Start customizing. :)

Thanks to mbaird for putting me on the right track.

[edit] I needed to look up my own answer again, and I spent at least ten minutes searching the official android styles/themes files, so here they are, for future reference: styles.xml and themes.xml.
