Android Question Simulate Enter keypress

[dim]

Hi all,
I have an edittext with an "EnterPressed" event that does something (beeps).
Using the device's keyboard I can write in the edittext and then pressing the device's keyboard's "Enter key" the EnterPressed event is fired fine.

Now I added a button that generates a string and pressing it, code is :

Button1.Text = "abc"
EditText1.Text = Button1.Text

So the text that the button generates is written in the Editext. No EnterPressed event so far.
So I changed code to :

Button1.Text = "abc" & CRLF

but still EnterPressed event is not fired.
What I am doing wrong ?
Thank you

Just call the sub yourself.

Button1.Text = "abc"
EditText1.Text = Button1.Text
EditText1_EnterPressed

Thank you Erel, but may I ask what is the actual difference between calling the "Enterpressed" myself and adding the CRLF in the end of the string ?

 

[Erel]

The EnterPressed event is raised when the user clicks on the enter or done button. It is not raised when the text is changed programmatically.

So, if I use barcode scanner that sends CRLF automatically after the string that it scans, it wont automatically submit in my android app ?

Yes. That is correct.

It would be better to use the barcode scanner in SPP mode and use AsyncStreams.

Thank you. As I wrote, the barcode scanner includes the CRLF after every string it sends. If the component cannot use it, maybe it's better me to try to read it in the string that it's been written. Is that correct ?

You could try handling the EditText1_TextChanged event. It seems to work!

Sub EditText1_TextChanged (Old As String, New As String)
    If New.EndsWith(CRLF) Then
        EditText1_EnterPressed
    End If
End Sub

It will probably cause the event to be raised as the barcode sends key strokes events. You need to test it.

Thank you guys, tomorrow I receive my barcode scanner and will test it.
BTW, Erel your development platform B4* rocks !
