Android Question Activity_KeyPress not firing after Activity.RemoveAllViews

[TheMightySwe]

Hi,

To my application i have a barcode-scanner connected as a Bluetooth keyboard. It works fine in the first screen on my app, but if i reset the activitys views with Activity.RemoveAllViews and draw new views the Activity_KeyPress isnt firing anymore.

I have tried to add Activity.RequestFocus after redrawing all the views.

Does anyone has any idea what the problem can be?

Tried this code:

Sub Activity_Create(FirstTime As Boolean)
   Activity.RemoveAllViews
End Sub

Sub Activity_KeyPress (KeyCode As Int) As Boolean 'Return True to consume the event
   Log(KeyCode)
   Return True
End Sub

Works correctly.

I'm posting a video to show the problem.

Tried this code:

Sub Activity_Create(FirstTime As Boolean)
   Activity.RemoveAllViews
End Sub

Sub Activity_KeyPress (KeyCode As Int) As Boolean 'Return True to consume the event
   Log(KeyCode)
   Return True
End Sub

Works correctly.

Look at video.

1. First scanner works...
2. I start other part of program
3. Scanner don't work
4. I click on a button
5. Scanner works again.


The video shows the problem. Maybe it's the Toastmessage that screws things up?

Activiyt_KeyPress event is only raised if the key press is not already handled by a different view. Maybe the focus has changed and now another view is consuming this event?

Hi, I removed the Custom_Toastmessage, and it works like a charm again.
