The documentation for android:backgroundDimAmount says:
"public static final int backgroundDimAmount
Default background dim amount when a menu, dialog, or something similar pops up. Must be a floating point value, such as "1.2".
This may also be a reference to a resource (in the form "@[package:]type:name") or theme attribute (in the form "?[package:][type:]name") containing a value of this type.
Constant Value: 16842802 (0x01010032)"
What is this float, 1.2, actually mean? What number signifies having 100% fade out (what's the highest number float I can use?)?
