Android Question IconButton(s) which one was clicked

[Rusty]

I have installed several iconbuttons on my activity.
Each one is directed to the same "click" event. I need to determine which one was clicked. I set a Tag value that tells me which one it was, but...
When the click event fires, I do this:

Sub icbCategory_Click
    Try
        Dim ThisIconButton As IconButton
        ThisIconButton = Sender
        Dim tg As string
        tg = ThisIconButton.tag
log("thisiconbutton " & thisiconbutton.tag)
    Catch
        Log("icbCategory_Click error " & LastException.Message)
    End Try
End Sub

It abends and logs:

Error occurred on line: 2767 (Main)

I don't understand the error. Is the iconbutton not a view?
any help will be appreciated.

Hi Don,
The Demo program provided shows the CLICK event and it works but doesn't provide any information that I can find that is useful, through normal means.



I was trying to use your iconify library but it fails. I posted it earlier today.
It dies on the loadlayout with

    Activity.LoadLayout("Layout1")

line 83 is the Activity.loadlayout above

Any suggestions? We can move this to another thread if you wish.
Thanks,

The library has a problem it looks like....
It is in a "old style" from me... I´ve changed due to b4a6....
I´ll rewrite/update the lib the next days. But as of now i´ve not the time asi´mworking on a customer wrapper

 

[Rusty]

Thanks Don.
Good luck with your customer wrapper
Rusty

 

[DonManfred]

For me it works with V1.13

Sub IconButton_Click()
    Log("Button click")
    Dim ib As IconButton = Sender
    Log(ib.Tag)   
   
End Sub

results in

** Activity (main) Create, isFirst = true **
** Activity (main) Resume **
Button click
Android
Button click
BarCode
Button click

... my mistake.
Apparently, I had an iconbutton.jar in my main Android libraries folder and I was putting the new one in the additional libraries.
I removed the one in the main folder and now it works in the demonstration program where the iconbutton is added to the Activity.

One last question, is there a way to change the text size and gravity?
Thanks Don!
