Android Question Got Focus for all EditText Views

[Guenter Becker]

Let' say on a layout I have 3 edittext views A,B,C.
In the activity or b4xpage I now I can intercept the fired focus event by sub A_FocusChange(..) a.s.o. Now Let's say I want to show a toast message if one of the edittext views got the focus. Up to now I understand that I have to put the toast show codeline in each of the 3 FocusChanged subs. That works but it blows up the lines of code.

Question: Is it possible (and if yes how to code) to have one sub routine with intercepts all FocusChange Events of all Views type edittext in a layout?

Thank for your help and stay well

Set a same event name for all EditText views.
Set different values for the Tag property.
In the event routine use the Sender keyword to get the view which raised the event.

Hi Klaus,
thank you for your answer but that is what my question goes for.
I tried:

sub A_FocusChanged(HasFocus as Boolean)
' this works
end sub

sub EditText_FocusChanged(HasFocus as Boolean)
' this works not.
end sub

How to set the same event name. Could you give a b4a code example .
best regards Günter
