I found solution
I add panel to activity and set gray color to it
And when menu opend,i show panel and when menu is hidden,i hide panel

below code

Dim overlayPanel as Panel
overlayPanel.Initialize("")
    overlayPanel.Color = Colors.ARGB(170,30, 30, 30)
    getCurrentActivity.AddView(overlayPanel,0,0,100%x,100%y)
    overlayPanel.Visible = False
   
    Dim jo As JavaObject = sm
    Dim event As Object = jo.CreateEventFromUI("com.jeremyfeinstein.slidingmenu.lib.SlidingMenu$OnOpenListener", "Open", Null)
    jo.RunMethod("setSecondaryOnOpenListner", Array(event)) 'setSecondaryOnOpenListner
   
    Dim jo As JavaObject = sm
    Dim event As Object = jo.CreateEventFromUI("com.jeremyfeinstein.slidingmenu.lib.SlidingMenu$OnCloseListener", "Close", Null)
    jo.RunMethod("setOnCloseListener", Array(event))

Sub Close_Event (MethodName As String, Args() As Object) As Object
   overlayPanel.SetVisibleAnimated(500,False)
End Sub

Sub Open_Event (MethodName As String, Args() As Object) As Object
   overlayPanel.SetVisibleAnimated(500,True)
End Sub

Sub getCurrentActivity As Activity
   Dim r As Reflector
   r.Target = r.GetActivityBA
   Return r.GetField("vg")
End Sub
