Android Question B4XComboBox GradientDrawable [Resolved]

[Sergey_New]

I create two B4XComboBoxes in the constructor.
I give them equal properties. For B4XComboBox1 in the constructor, for B4XComboBox2 at runtime:

Sub Activity_Create(FirstTime As Boolean)
    Activity.LoadLayout("Layout")
    B4XComboBox2.cmbBox.Background=setGradientDrawable
End Sub

Sub setGradientDrawable As GradientDrawable
    Dim gr As GradientDrawable
    Dim cls(2) As Int
    cls(0)=Colors.ARGB(255,124,245,239)
    cls(1)=Colors.ARGB(255,13,142,137)
    gr.Initialize("TOP_BOTTOM",cls)
    gr.CornerRadius=8
    Return gr
End Sub

Why do they look different?

You should set the color of B4XComboBox.mBase.

Erel,
I didn't understand why set the color? I need a gradient fill.
Tell me the code how to do this so that the arrow is visible.

B4XComboBox2.mBase.Background=setGradientDrawable

Error:

 

[Erel]

Dim pnl as Panel = B4XComboBox2.mBase
pnl.Background = setGradientDrawable

Erel, thank you very much!
