Change button colors

mrossen · May 7, 2012

Hi,

Is it possible to change the released and the pressed color for at button.

I haved changes the button to have 0dip corners but now can I not see if the button is pressed.

I have used this code to remove the corners.

B4X:

Dim cdwColor As ColorDrawable
   cdwColor.Initialize(Colors.Transparent , 0dip)
   ButtonAnswer.TextColor  = Colors.White 
   ButtonNext.textColor = Colors.White
   ButtonAnswer.Background = cdwColor
   ButtonNext.Background = cdwColor

It is easier to do it with the visual designer.

If you want to do it programmatically then you should use a StateListDrawable.
Basic4android Search: StateListDrawable

Hi Erel,

Yes you are right, but I need to have the buttons fixed in the bottom of the screen and the rest of the screen in a Scrollview.

So I have done this

B4X:

ScrollViewMain.Initialize(0)
   ScrollViewScore.Initialize(0)
   PanelMain.Initialize(0)
   PanelHighScore.Initialize(0)
   
   PanelMain = ScrollViewMain.Panel 
   Activity.AddView(ScrollViewMain, 0, 0, 100%x, 100%y - 50dip)
   
   If Activity.Height > 480dip Then
      PanelMain.Height = 100%y - 50dip
   Else
      PanelMain.Height = 430dip
   End If
   
   PanelMain.Width = 100%x
   PanelMain.LoadLayout("cast")
   ScrollViewMain.Visible = True
   
   ButtonAnswer.Initialize("ButtonAnswer")
   Activity.AddView(ButtonAnswer, 0%x, 100%y - 50dip, 50%x, 50dip)
   ButtonNext.Initialize("ButtonNext")
   Activity.AddView(ButtonNext, 50%x, 100%y - 50dip, 50%x, 50dip)

Can I do this in the designer?

BTW, I love the new Script Designer

Can I do this in the designer?

Yes: Button1.Buttom = 100%y

See this example: http://www.b4x.com/forum/designer-layouts/17460-useful-tempate-1-a.html

change button color

Can in use a variable to change the button colors?

example:
COLOR = "color.red"
Btn1.COLOR = COLOR

B4X:

Dim clr As Int
clr = Color.Red

Btn1.Color = clr

color

but "red", "blue"...is a variable (string) from database

button1.color = color. & variable

or

dim clr as int
clr = color. & variable
button1.color = clr

how can i do?

I suggest you to use a Map.

B4X:

Dim Cols As Map
Cols.Initialize
Cols.Put("red", Colors.Red)
Cols.Put("blue"), Colors.Blue)
'
'
Button1.Color = Cols.Get(Color)

Where Color is the databsae variable.

Best regards.

Very good Klaus.

So simple of course. Maps are very useful I am finding.

I couldn't agree more.
