How to get the default alert Dialog on android have a black theme

Question

How do you get the black themed Dialog in android like shown on the android guide http://developer.android.com/guide/topics/ui/dialogs.html

I took a screen shot. Whenever I use Alert Dialog, I get the dialog on the left, I want the one on the right.

enter image description here

Try this but not sure. Go to android project-->layout-->xml file-->Graphical Layout-->change theme (Theme.Black) — Shailendra Madda, Oct 22 '13 at 15:45

It's simple for API 11 onwards:

AlertDialog.Builder alert = new AlertDialog.Builder(context, AlertDialog.THEME_DEVICE_DEFAULT_DARK);

The field THEME_DEVICE_DEFAULT_DARK was added in API 14 so if you are targeting before then, just use the numeric value, thus:

AlertDialog.Builder alert = new AlertDialog.Builder(context, 4);

The different constants you can use, and their values are shown here. On pre API 14 you will still get the white alert though.

----------------------------------------------------------------UPDATE--------------------------------------------------------

AlertDialog.THEME_DEVICE_DEFAULT_DARK is depreciated,

Below is the updated code:

AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(this, android.R.style.Theme_DeviceDefault_Light_Dialog_Alert);

You can choose different themes instead of this android.R.style.Theme_DeviceDefault_Light_Dialog_Alert

This theme worked for me, to get a light theme: `Theme_Material_Light_Dialog_Alert` – T.Coutlakis May 08 '17 at 14:29

The dark one is now `android.R.style.Theme_DeviceDefault_Dialog_Alert` according to your link (and my experiments): http://developer.android.com/reference/android/app/AlertDialog.html#THEME_DEVICE_DEFAULT_DARK – Johan Walles Nov 08 '18 at 08:31

If you don't want to change your Activity's theme, you can extend AlertDialog and supply the Theme.Holo in its contructor: AlertDialog(Context context, int theme).

In case of using DialogFragment to implement customised dialog, set the theme in onCreate() method like this:

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState)
    setStyle(DialogFragment.STYLE_NORMAL, android.R.style.Theme_Holo_Dialog)
}
