I will not do your work!
It is you who have this requirement, not me. So YOU should find a solution for it.

Search the forum on how to do that what you want please.

 

[DonManfred]

Little example

https://www.b4x.com/android/forum/t...-toast-with-iconfont-icons.64583/#post-409075
With this lib you should be able to generate Drawables using FontAwesome

Thanks for the information.

I got this error:

and you are not providing enough information.
Which Android.jar are you using?
What is the targetsdk in manifest?
Are the two maven repos are uptodate?

With BottomNavigationEx.zip and BottomNavigationV1.1.zip, I got this error:

add the resourcefolder from the example to your project.

 

[Mashiane]

Cool, how does one tag a menu e.g. show number of likes for example?

 

[DonManfred]

There are no methods to set a Badge in the Library.
Maybe you can use Erels BadgeClass to add one?

Solved !

it turns out, the resource file in the example (dimens.xml) is missing one line that is used for library 1.1

<dimen name="bottom_navigation_line_width">1dp</dimen>

old dimens.xml

<resources>
    <dimen name="bottom_navigation_elevation">8dp</dimen>
    <dimen name="bottom_navigation_shadow_height">8dp</dimen>
    <dimen name="bottom_navigation_shadow_height_without_colored_background">4dp</dimen>
    <dimen name="bottom_navigation_min_width">104dp</dimen>
    <dimen name="bottom_navigation_max_width">168dp</dimen>
    <dimen name="bottom_navigation_height">56dp</dimen>
    <dimen name="bottom_navigation_icon">24dp</dimen>
    <dimen name="bottom_navigation_padding_top_active">5dp</dimen>
    <dimen name="bottom_navigation_padding_top_inactive">9dp</dimen>
    <dimen name="bottom_navigation_padding_top_inactive_without_text">16dp</dimen>
    <dimen name="bottom_navigation_padding_bottom">7dp</dimen>
    <dimen name="bottom_navigation_padding_left">12dp</dimen>
    <dimen name="bottom_navigation_padding_right">12dp</dimen>
    <dimen name="bottom_navigation_text_size_active">14sp</dimen>
    <dimen name="bottom_navigation_text_size_inactive">12sp</dimen>
</resources>

new dimens.xml

<resources>
    <dimen name="bottom_navigation_elevation">8dp</dimen>
    <dimen name="bottom_navigation_shadow_height">8dp</dimen>
    <dimen name="bottom_navigation_shadow_height_without_colored_background">4dp</dimen>
    <dimen name="bottom_navigation_min_width">104dp</dimen>
    <dimen name="bottom_navigation_max_width">168dp</dimen>
    <dimen name="bottom_navigation_height">56dp</dimen>
    <dimen name="bottom_navigation_line_width">1dp</dimen>
    <dimen name="bottom_navigation_icon">24dp</dimen>
    <dimen name="bottom_navigation_padding_top_active">5dp</dimen>
    <dimen name="bottom_navigation_padding_top_inactive">9dp</dimen>
