Hi guys,

I need a simple combo box and B4XComboBox served well for this purpose.

It runs OK when using dark or light theme, but when using custom theme or not using it (set it in manifest file), triangle icon missing, see the attachment.

How to make it appear when using custom theme?

Edit : The triangle icon was not missing, but color of the icon set to black and if your background color is black too, icon seem missing.

Is it possible to change the color of the triangle icon?

All of my applications used black background, so no way I will change it only to use this view.

If not possible to change triangle color, will search for other solution.

It's simple: Unzip the corresponding b4xlib file and change the color to your liking

Not that simple.


Thanks anyone who have been helped me.

I will change B4XCombo to this spinner :

Nice Spinner

It wraps this Github project. It requires android-support-v4.jar (a recent version) to be in your additional library folder. You can download it from here. Posting the B4A project, the B4A library files, and the Java code. If you want to make changes to the Java code and recompile it you must...

This might be a solution to your problem...
Create a bitmap with an arrow in it and use that as bitmap for your B4XComboBox...
The B4XComboBox is added in the designer to a panel of the same size. This lets you set the background color.
The bitmap is transparant except for the arrow.
B4X: 
    Panel1.Color = Colors.Black        'Colors.White
    cbSnc.cmbBox.TextColor = Colors.White    '0xFFFFD700     'Colors.Black    '0xFFF5F5DC
    cbSnc.cmbBox.DropdownBackgroundColor = Colors.Black        '0xFF000000
    
    'cbSnc.mBase.SetBitmap(LoadBitmapResize(File.DirAssets,"arrow_down_black.png",270dip,40dip,True))
    cbSnc.mBase.SetBitmap(LoadBitmapResize(File.DirAssets,"arrow_down_white.png",270dip,40dip,True))
    'cbSnc.mBase.SetBitmap(LoadBitmapResize(File.DirAssets,"arrow_down_yellow.png",270dip,40dip,True))
Is this what you wanted to do?
