Android Question Reading BARCODE with scaner intetraged in TABLET

[netsistemas]

I need set focus to next control when the user read with button in TABLET (integrated), and detectit... and then sent focus to next control.

Keycode are number 61 but with scaner the char are 545

how detect and send then control to the next control.?

i think (error), that 'TABKEY IN TABLET KEYBOARD INTEGRATED' and 'NEXT KEY IN KEYBOAR IN SCREEN' and 'CHAR 545 with button integrated in table' are simil, but no, in any casy, the efect are diferent.

TABKEY and NEXT control there are not equal.

I see that you are already catching it.

If KeyCode = 545 Then B4XPages.MainPage.SomeSubThatWillDoWhatYouNeed

this event ONLY are cathing in main page of b4x.
how detect in other pages?

how cancel this key pressed?

finally, i solved the problem cathing the size in control (text.lenght) and then send focus to next control, but this questions are for future proyect and know this problem.

If KeyCode = 545 Then
   B4XPages.GetManager.RaiseEvent(B4XPages.GetManager.GetTopPage, "TAB_KEY_PRESSED", Null)
End If

You cannot cancel it.

and detect in other pages?
maybe put activity_keypress in other subpages? (i try, but no work)

This code, which should be added to the Main module will raise the event on the current top page.
