Activity_KeyPress ?

[susu]

Currently my App can be closed by 2 ways:

1. Tap menu Exit on screen.
2. Press back button on device.

But I only want to accept the "menu way" not "button way". I try to catch KeyPress event but I don't know how. Documentation doesn't mention about it too.

Here is some example which i use

Sub Activity_KeyPress (KeyCode As Int) As Boolean 'return true if you want to consume the event
    If KeyCode = KeyCodes.KEYCODE_BACK Then
       If panelSearch.Visible=True Then 
       panelSearch.Visible=False
       Return True
      End If 
   
        res = Msgbox2("Do you want to exit?", "", "Yes", "", "No", Null)
        If res = DialogResponse.NEGATIVE Then Return True
    End If
    Return False
End Sub

Something like:

Sub Activity_KeyPress (KeyCode As Int) As Boolean 'return true if you want to consume the event
    If keycode = KeyCodes.KEYCODE_BACK Then
        Return True
    Else
        Return False
    End If
End Sub

I want activity ignores back button, home button and only close after user press menu button 3 times. My code below:

Sub Globals
   Dim menucount As Int
End Sub

Sub Activity_Create(FirstTime As Boolean)
   menucount = 0
End Sub

Sub Activity_KeyPress (KeyCode As Int) As Boolean

    If Keycode = KeyCodes.KEYCODE_BACK Then
        Return True
    End If

    If Keycode = KeyCodes.KEYCODE_MENU Then
   Return True
    End If
    
    If Keycode = KeyCodes.KEYCODE_MENU Then
   menucount = menucount + 1
   If menucount = 3 Then
   Activity.Finish
   End If
    End If
   
End Sub

It compiled ok but it doesn't work as I want. It ignores back button not home button and nothing happen when I press menu button 3 times. Something's wrong here? :sign0085:

The Home button cannot be caught. This is a "feature" of the OS. I'm not sure about the Menu button. But it is likely that it does not get caught as well.

If you look at your code!
In the 2nd and in the 3rd If statement you test the same KeyCode !
Replace your code by :

Sub Activity_KeyPress (KeyCode As Int) As Boolean
 
    If Keycode = KeyCodes.KEYCODE_BACK Then
        Return True
    End If
 
    [COLOR=red]If Keycode = KeyCodes.KEYCODE_HOME[/COLOR] Then
    Return True
    End If
 
    If Keycode = KeyCodes.KEYCODE_MENU Then
    menucount = menucount + 1
    If menucount = 3 Then
    Activity.Finish
    End If
    End If
 
End Sub

Should work.

Best regatrds.

Thanks Erel, I can live with this "feature"
Thanks Klaus, it's my mistake. Now activity closed after press menu button 3 times.
