My Final Code:

B4X: 
Sub Globals
    Private ActivityHeight As Int = 0
End Sub

B4X: 
Sub Activity_Create(FirstTime As Boolean)
    Activity.LoadLayout("Layout1")
    ActivityHeight = Activity.Height
End Sub

B4X: 
Sub IME_HeightChanged(NewHeight As Int, OldHeight As Int)
    Private IsIMEKeyboardClosed As Boolean = (NewHeight = ActivityHeight)
    LogColor("IsIMEKeyboardClosed >>   " & IsIMEKeyboardClosed, Colors.Red)
End Sub
