I am using B4XComboBox having textcolor white. However, as text color is set white, when clicked on combo box to select the item, user can not see the values as background after click is also white. Attached is the snapshot for the reference.

I have tried following code but it does change background of ComboBox however on
ComBox background color change: 
    Dim cd As ColorDrawable
    cd.Initialize(Colors.Transparent,0)
    ComboBox1.cmbBox.Background=cd
click background remains white.

change the theme from dark to light (or the opposite) in the manifest editor.

I have never used manifest to apply the them. Can you please provide syntax for the same?
However, in some cases ComboBox requires light theme and in some cases dark theme then i believe manifest editor will not be useful.

B4X: 
Dim b As B4XView=B4XComboBox2.cmbBox
    b.SetColorAndBorder(xui.Color_Red, 5dip, xui.Color_Yellow, 10dip)

B4X: 
B4XComboBox2.cmbBox.DropdownBackgroundColor =xui.Color_Magenta

For the manifest:
B4X: 
CreateResourceFromFile(Macro, Themes.DarkTheme)
or:
B4X: 
CreateResourceFromFile(Macro, Themes.LightTheme)

Thanks for nice feedback.

I have a doubt...I can either apply dark or light theme, now suppose, if i apply dark theme however in case (in same project) combo box is required light then i need to apply colors for light theme by coding?
