Amazing, Manfred.
Your sample project is raising this error message though
B4X:
lib: NOTFOUND 'navigation_onnavigationitemclick

Regards

SOLVED: There is no "onNavigationItemClick" sub in the original sample project. After creating this sub, it worked just fine.

Thanks!

Really nice!
Works only in Android 5+?
I tried in versions 5 and 6 and works fine, but I have issues in 4.0 and 4.4.
In 4.0 the navigation was not showed.
In 4.4 I don't see the icons and I have a little dark space in the top of navigation and a white space in the bottom.

the line #AdditionalRes: ..\Resource is for load what?
To load the additional resources for this object.

See content of folder Resource.
Here you can place the pngs to use in the drawables folder.
Additional the resource folder holds the layout of the button bar in folder Layout and the objectstructure in attr.xml

Thanks you for your reply. DonManfred.

I am a little bit confused, because in /Resource has the files, all of them are there, but the IDE show this:
Perhaps my android-support-v4.jar in Additional Libraries is out to date?, or the SDK 19 and need newest SDK version.
What do you think? say " in package android" mmm

Did you added the Resourcefolder from the sample? Did you added the #Additionalres command in your project?

Now I added folder.

Code break down on this line and app stoped.
Navigation.ItemActiveColorWithoutColoredBackground = Colors.Gray


java.lang.NoSuchMethodError: No static method getColor(Landroid/content/Context;I)I in class Landroid/support/v4/content/ContextCompat; or its super classes (declaration of 'android.support.v4.content.ContextCompat' appears in /data/app/contact.backup-2/base.apk)

I want to use IME with this and tried using
IME_HeightChanged (NewHeight As Int, OldHeight As Int) event. But log says "Ignoring event: ime_heightchanged".
any reason?

any reason?
I don´t know.

But your issue seems not to be related to the bottomnavigationlib.
There is no HeightChanged event which is raised by the lib. Maybe it is part of the b4a viewWrapper Class...

You should start a new thread in the questionsforum for your issue. Maybe post some example code which shows the problem.

This looks very promising. But for the Icons I find the hassle with the vector drawables (in xhdpi, xxhdpi, xxxhdpi) very unproductive.
I would like to use Android-Iconics icon font (introduced by thedesolatesoul with the MSMaterialDrawer).

Since the Navigation Items only work with imageResource I need to find a way to use the icon font for the BottomNavigationItems.


  • BottomNavigationItem
    Methods:
    • Initialize (title As String, color As Int, imageResource As String)
    • IsInitialized As Boolean
    • setImageResource (imageResource As String)
    Properties:
    • Color As Int
    • ImageResource As Int [read only]
    • Title As String


Would it be possible to extend the library to accept icon fonts?


Or do you know another way of doing that?
