Custom Button Colors

[Bill Norris]

This is a modified sample of code previously posted, to demonstrate how to manually set customized button colors. I have two buttons on the activity, button1 and button2.

It works fine when just using button1. However, if you add to end of the code

button2.Background = stdGreenColor

Strange behavior occurs. If I touch button1, button2 changes color but botton1 does not.

My ultimate goal is to apply a custom gradient to all of the buttons on the activity. This code does not use gradients but the basic principles are the same.

dim button1 as button
dim button2 as button

   Dim cdGreenColorEnabled As ColorDrawable
  cdGreenColorEnabled.Initialize(Colors.yellow,10)
  ' Define a color for Pressed state
  Dim cdGreenColorPressed As ColorDrawable
  cdGreenColorPressed.Initialize(Colors.Red,10)
  ' Define a StateListDrawable
  Dim stdGreenColor As StateListDrawable
  stdGreenColor.Initialize
  Dim states(2) As Int
  states(0) = stdGreenColor.state_enabled
  states(1) = -stdGreenColor.state_pressed
  stdGreenColor.addState2(states, cdGreenColorEnabled)
  Dim states(1) As Int
  states(0) = stdGreenColor.state_pressed
  stdGreenColor.addState2(states, cdGreenColorPressed)
  ' Set stdGreenColor to button background 
 button1.Background = stdGreenColor

Thanks for any assistance.

You need to define a new Drawable object (ColorDrawablw, GradientDrawable or BitmapDrawable) for each button. Otherwise the different buttons refer to the same Drawable.

Best regards.

Yes, I seem to have discovered that. I was able to define the statelistdrawable object as an array, then assign each button's background to a different element of the array. Works like a charm.
