Android Question How to check if a view is an Activity or a Panel

klaus · Nov 15, 2013

I need to know if a view is an Activity or a Panel.
What's the best way to check it ?
If View Is Activity Then is True even if View is a Panel.
and GetType(View) returns the syme type.
both don't work because Activity and Panel seem to be considered beeing the same in B4A?

C'est la colle du mois !
I'm unable to give a proper answer. Here's a stupid but working workaround:

B4X:

Sub DisplayClass(Obj As Activity)
    Try
        Obj.GetStartingIntent
        Log("this is an activity")
    Catch
        Log("this is a panel")
    End Try
End Sub

Merci Fred.
At the moment I use another workaround.
I check the type of the parent view.

B4X:

If GetType(GetParent(v1)) = "android.widget.FrameLayout" Then
    ' Activity
Else
    ' Panel
End If

Private Sub GetParent(v As Object) As Object
    Dim jobj = v As JavaObject
    Return jobj.RunMethod("getParent", Null)
End Sub

But yours looks easier .
