I have code to generate my own QWERTY keyboard on screen. The game that this will be part of will require the keyboard button images (pressed and unpressed) to change throughout the game.
The generation of the keyboard is not a problem. The question is, given the code below that generates the key buttons, is it possible to re-access the "button()" array and change individual Enabled and Pressed images for any specific button? Any key that needs to be changed will be accessed by an index into the array (0-25) according to the order that they were generated.
Here's the code to generate the keyboard:
"KeyLegends" is defined as a string as:
"QWERTYUIOPASDFGHJKLZXCVBNM",
and I'm currently using only a 320x480 variant.
The other keyboard background images will be:
btnunpressed20x15Hilite.png, btnPressed20x15Hilite.png
and
btnunpressed20x15Elim.png, btnPressed20x15Elim.png
Thanks in advance for your help.

Here's the code to generate the keyboard:
B4X:
'Place keyboard on screen
For i = 0 To 25
If i<10 Then
OffsetX = (100%x - (10-i) * (Width-3) - 10)
OffsetY = 100%y - Width * 4 + 20
Else If i<19 Then
OffsetX = (100%x - (20-i) * (Width-3) + 8)
OffsetY = 100%y - Width * 3 + 13
Else
OffsetX = (100%x - (28-i) * (Width-3) - 3)
OffsetY = 100%y - Width * 2 + 6
End If
Dim b As Button
b.Initialize("button")
Activity.AddView(b,OffsetX, OffsetY, Width, Width-5)
' Define a bitmap for Enabled state
Dim bdwEnabled As BitmapDrawable
bdwEnabled.Initialize(LoadBitmap(File.DirAssets, "btnunpressed20x15.png"))
' Define a bitmap for Pressed state
Dim bdwPressed As BitmapDrawable
bdwPressed.Initialize(LoadBitmap(File.DirAssets, "BtnPressed20x15.png"))
' Define a StateListDrawable
Dim stdBitmap As StateListDrawable
stdBitmap.Initialize
Dim states(2) As Int
states(0) = stdBitmap.state_enabled
states(1) = -stdBitmap.state_pressed
stdBitmap.addState2(states, bdwEnabled)
Dim states(1) As Int
states(0) = stdBitmap.state_enabled
stdBitmap.addState2(states, bdwPressed)
' Set stdBitmap to button btnBitmap
b.Background = stdBitmap
b.Typeface = Typeface.MONOSPACE
b.TextSize = 14 'was 12
b.Text = KeyLegends.SubString2(i,i+1)
b.Tag = Asc (b.Text)-65
b.TextColor = Colors.Black
Button(i) = b
Next"KeyLegends" is defined as a string as:
"QWERTYUIOPASDFGHJKLZXCVBNM",
and I'm currently using only a 320x480 variant.
The other keyboard background images will be:
btnunpressed20x15Hilite.png, btnPressed20x15Hilite.png
and
btnunpressed20x15Elim.png, btnPressed20x15Elim.png
