If you just want a light theme and aren t particular about the specific color  then you can pass a theme id to the AlertDialog Builder constructor   AlertDialog Builder this  AlertDialog THEME HOLO LIGHT       or  AlertDialog Builder this  AlertDialog THEME DEVICE DEFAULT LIGHT

To expand on  DaneWhite s answer  you don t have to rely on the built-in themes  You can easily supply your own style    lt style name  MyDialogTheme  parent  Theme AppCompat Light Dialog Alert  gt       lt item name  android background  gt  color myColor lt  item gt   lt  style gt    and then apply it in the Builder constructor   Java   AlertDialog alertDialog   new AlertDialog Builder getContext    R style MyDialogTheme                       create      Kotlin    var alertDialog   AlertDialog Builder context  R style MyDialogTheme                       create     This should work whether you are using android support v7 app AlertDialog or android app AlertDialog  This also works better than  DummyData s answer because you don t resize the dialog  If you set window s background drawable you overwrite some existing dimensional information and get a dialog that is not standard width   If you set background on theme and the set the theme on dialog you ll end up with a dialog that is colored how you want but still the correct width

For any dialog called myDialog  after calling myDialog show    you can call   myDialog getWindow   getDecorView   getBackground   setColorFilter new LightingColorFilter 0xFF000000  CUSTOM COLOR      where CUSTOM COLOR is in 8-digit hex format  ex  0xFF303030  Here  FF is the alpha value and the rest is the color value in hex

I order to change the dialog buttons and background colors  you will need to extend the Dialog theme  eg     lt style name  MyDialogStyle  parent  android Theme Material Light Dialog NoActionBar  gt       lt item name  android buttonBarButtonStyle  gt  style MyButtonsStyle lt  item gt       lt item name  android colorBackground  gt  color white lt  item gt   lt  style gt    lt style name  MyButtonsStyle  parent  Widget AppCompat Button ButtonBar AlertDialog  gt       lt item name  android textColor  gt  color light blue lt  item gt   lt  style gt    After that  you need to pass this custom style to the dialog builder  eg  like this   AlertDialog Builder requireContext    R style MyDialogStyle    If you want to change the color of the text inside the dialog  you can pass a custom view to this Builder    AlertDialog Builder setView View    or   AlertDialog Builder setView  LayoutResource int
