Android Question Button problems with gradient fill background

[Lakhtin_V]

If I use rectangular buttons and a simple background color, I have no problem. If I use a button with a gradient fill and round corners there are problems. Sometimes the buttons are displayed incorrectly. I can not understand the reason for this problem.

Do you define the Buttons in the code or in the Designer.
I suppose in the code, and you define a GradientDrawable object and you use the same for several Buttons with different dimensions, you need to define one GradientDrawable for each Button.

With this code should work.

Public Sub DrawButton(btn As Button, Color1 As Int, Color2 As Int)
    Dim dr As GradientDrawable
    dr.Initialize("TOP_BOTTOM", Array As Int(Color1, Color2))
    dr.CornerRadius = 10dip
    btn.Background = dr
End Sub

Sub Globals
    ....
    Public gdUPnav As GradientDrawable, gdDOWNnav As GradientDrawable, gdUPevent As GradientDrawable, gdDOWNevent As GradientDrawable
    ....
End Sub

Sub Activity_Create(FirstTime As Boolean)
    ....
    gdUPnav.Initialize("BL_TR", Main.clrNavUP)
    gdUPnav.CornerRadius=Main.Rad
    gdDOWNnav.Initialize("BL_TR", Main.clrNavDOWN)
    gdDOWNnav.CornerRadius=Main.Rad
    gdUPevent.Initialize("BL_TR", Main.clrEventUP)
    gdUPevent.CornerRadius=Main.Rad
    gdDOWNevent.Initialize("BL_TR", Main.clrEventDOWN)
    gdDOWNevent.CornerRadius=Main.Rad
    .....
End Sub

    ....
    btn.Initialize("btnZvonok")
    str="Звонок консультанту"
    btn.Text=str
    btn.TextSize=Main.fSred
    btn.Background=gdUPevent
    btn.TextColor=Colors.DarkGray
    Activity.AddView(btn, 3%x, 76%y, 37%x, 10%y)
    ....

Thank you Klaus
Do you recommend to describe each button individually?

    ....
    btn.Initialize("btnZvonok")
    str="Звонок консультанту"
    btn.Text=str
    btn.TextSize=Main.fSred
    gdUPevent.Initialize("BL_TR", Main.clrEventUP)
    gdUPevent.CornerRadius=Main.Rad
    btn.Background=gdUPevent
    btn.TextColor=Colors.DarkGray
    Activity.AddView(btn, 3%x, 76%y, 37%x, 10%y)
    ....

Make sure to use a different Gradient-drawable for the Buttons.
Do not use the same Gradient(-Drawable) for more than one button

 

[klaus]

For the GradientDrawables yes.

 

[DonManfred]

For the GradientDrawables yes.

Yes, i meant the drawables. Sorry if this was not clear.

No, you were faster than me.
