Question

I want to apply a style like the Graphical Layout shows as Theme.DeviceDefault.Dialog.Alert. I know that it’s a private style now, and I can’t take it as parent.

What can I do to have that style to my DialogFragment?

(I’m targeting API 15, and maybe I want to minSdk API 12).

This reports me an error (the parent, like I read, it’s private now):

<style name="MyDialogStyle" parent="@android:style/Theme.DeviceDefault.Dialog.Alert">

No resource found that matches the given name.

I just read that I must “copy” the items of style, but I don’t find where is it?

Could anyone help me, please? I need to “clone” that style to my custom style.

Thanks in advance.

Things I have tried:

Hardcoded background for DialogFragment

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    getDialog().getWindow().setBackgroundDrawable(new ColorDrawable(0));

    return super.onCreateView(inflater, container, savedInstanceState);
}

My Custom Style

<style name="MyDialogStyle">    
    <item name="android:windowBackground">@android:color/transparent</item>
    <item name="android:background">@android:color/transparent</item>
    <item name="android:windowIsTranslucent">true</item>
    <item name="android:windowContentOverlay">@null</item>
</style>

Finally I solved this problem with a Dialog instead a DialogFragment because this last one doesn’t support transparency layout. It was easy set the transparent background making a new activity and set the style in Manifest. Otherwise I had to change the structure of dialogs using activities instead fragments.

I hope this saves someone many hours of research.

Bye!
