In Android when you pop up a dialog the screen behind it dims. Is there any way to control what that looks like? For example making it dim more or less or using some kind of a pattern?

Android DialogFragments. DialogFragment is a utility class which extends the Fragment class. It is a part of the v4 support library and is used to display an overlay modal window within an activity that floats on top of the rest of the content. Essentially a DialogFragment displays a Dialog but inside a Fragment.
Showing the DialogFragment It is not necessary to manually create a FragmentTransaction to display your DialogFragment . Instead, use the show() method to display your dialog. You can pass a reference to a FragmentManager and a String to use as a FragmentTransaction tag.

Yes, it is. You can control it.
After creating dialog:
WindowManager.LayoutParams lp = dialog.getWindow().getAttributes(); lp.dimAmount = 0.0f; // Dim level. 0.0 - no dim, 1.0 - completely opaque dialog.getWindow().setAttributes(lp); Upd: you can even add blur behind the dialog:
dialog.getWindow().addFlags(WindowManager.LayoutParams.FLAG_BLUR_BEHIND); Upd2: Blurring is deprecated since API14:
This constant was deprecated in API level 14.
Blurring is no longer supported.
