Android Question [Solve] SetColorAnimated with Corner Radius

rraswisak · Jan 3, 2019

Hi all,

I have a label with corner radius set to 20, then i want to change the color with SetColorAnimated method, the color was change but the corner radius is missing.

B4X:

Sub Label1_Click
     Dim Col1, Col2 As Int
     Col1 = Colors.Red
     Col2 = Colors.Green

     Label1.SetColorAnimated(500, Col1, Col2)
End Sub

If i define Col1 and Col2 as ColorDrawable, it raise error

B4X:

Sub Label1_Click
     Dim col1, col2 As ColorDrawable
     col1.Initialize(Colors.ARGB(175,255,0,0),20dip)
     col2.Initialize(Colors.ARGB(175,0,255,0),20dip)
     Label1.SetColorAnimated(500, Col1, Col2)
End Sub

Use B4XView.SetColorAnimated. It looks and works better.

B4X:

Sub Globals
   Private Label1 As B4XView
   Private xui As XUI
End Sub

Sub Activity_Create(FirstTime As Boolean)
   Activity.LoadLayout("1")
End Sub

Sub Activity_Click
   Label1.SetColorAnimated(1000, xui.Color_Red, xui.Color_Blue)
End Sub

Thank you erel, but i think SetColorAnimated will remove corner radius previously set in designer.

So every time color has change, the corner radius will gone

Without Animated, i can change the color with ColorDrawable, in this case i want to use SetColorAnimated

Have you tried it?

rraswisak · Jan 3, 2019

Yes its work, but sorry i miss one information, in designer, i set label drawable to GradientDrawable.

try to figure it out with this code, but still get error:

B4X:

Sub Label1_Click
   Dim col1, col2 As GradientDrawable
   Dim c1(2), c2(2) As Int
   c1(0) = xui.Color_Blue
   c1(1) = xui.Color_White
   col1.Initialize("TOP_BOTTOM",c1)
   col1.CornerRadius = 20
   
   c2(0) = xui.Color_Red
   c2(1) = xui.Color_White
   col2.Initialize("TOP_BOTTOM",c2)
   col2.CornerRadius = 20
   
   If posLeft Then
       Label1.SetColorAnimated(500,col1, col2)
   Else
       Label1.SetColorAnimated(500,col2, col1)
   End If
   posLeft = Not(posLeft)
End Sub

Your code is wrong. You should carefully follow the code I posted and understand how to use it.

this is final result:

thank you for all your support
