    Steps I took:

    • Create a class extending Dialog.
    • In the onCreate, call setContentView(x, y) with x being your R.layout and y being R.style.popupStyle (see below).
    • 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.

    for reference: styles.xml and themes.xml.
