Android Question Accessing Window Manager layout params?

mr23 · Jan 26, 2014

How does one access a WM layout param value from B4A (from I assume) using reflection?
Specifically this pair:
http://developer.android.com/reference/android/view/WindowManager.LayoutParams.html#dimAmount
and
http://developer.android.com/reference/android/view/WindowManager.LayoutParams.html#FLAG_DIM_BEHIND

Lets start with the simple one. FLAG_DIM_BEHIND is a constant. Its value is 2.

Try this code, it will only work on Android 4+:

B4X:

Dim jo As JavaObject = Activity
Dim Window As JavaObject = jo.RunMethodJO("getContext", Null).RunMethod("getWindow", Null)
Window.RunMethod("addFlags", Array As Object(2))
Dim dimAmount As Float = 0.8
Window.RunMethod("setDimAmount", Array As Object(dimAmount))

Thank you, Erel, that does allow modifying the dim amount. Tested on 4.4.2 on a kindle fire gen1.
