Android Question know from what class is derived an object

[Roberto P.]

I need to know what class is derived an object of custom controls.

I know the function:

If CallBack Is Activity Then

end if

specifically I need to know the class membership of the object that is passed in the custom controls.

Public Sub Initialize (vCallback As Object, vEventName As String)
    EventName = vEventName
    CallBack = vCallback
   
    If CallBack Is Activity Then
        Log("è una activita")
    else if CallBack Is Panel Then
        Log("è un pannello")
    End If
   
End Sub

thanks

It is difficult to distinguish between activities and panels because both of them are based on the same internal type.

What do you need it for?

If you needed only to know:

If CallBack Is Activity Then

maybe you can use (or adapt) this routine (it is from module Scale):

'Returns True If the View v Is an Activity otherwise False
'Needed to check if the view is a Panel or an Activity
Public Sub IsActivity(v As View) As Boolean
    Dim obj As Object
    obj = GetParent(v)
    If GetType(obj) = "android.widget.FrameLayout" Then
        Return True
    Else
        Return False
    End If
End Sub

It might not be correct in all cases.

I need to know what is the parent class of the object, to make the correct cast with the subject "vCallback"
So, how do I know which class an object belongs?
I hope it is clear

Please post the code where you need to know the class type.
