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'm getting the same error about getColor method...

 

[Mashiane]

I'm getting the same error about getColor method...

Got, android-support.v4.jar from here and put in my my libraries folder and this worked perfectly. Wow, thanks!

 

[Mashiane]

Would be nice to be able to change the title or icon in run-time depending on some variables otherwise perfect stuff.

Tell me, how does one generate the xml from images to use in this? I want to try other icons.

Thanks a lot!

 

[tuhatinhvn]

how to set height and change icon??

your library are always very little information and very hard to use!

 

[DonManfred]

I want to try other icons.

you can use any possible drawable (which must be placed in res/drawable.
Put a myicon.png into this folder and add the tab with

    Dim Item As BottomNavigationItem
    Item.Initialize("Favorite",Colors.Blue,"myicon")
    Navigation.addTab(Item)

https://developer.android.com/index.html#q=drawable

 

[tuhatinhvn]

How to change height of it?

 

[Mashiane]

I have played around with this, here is another example.

Sub Activity_Create(FirstTime As Boolean)
    'Do not forget to load the layout file created with the visual designer. For example:
    Activity.LoadLayout("Layout1")
    ' this is the color of a selected item when isColoredBackground(False)
    Navigation.ItemActiveColorWithoutColoredBackground = Colors.Magenta
    ' background color of navigation bar
    Navigation.Color = Colors.green
    ' when an item is clicked, does the color change? True = Yes
    Navigation.isColoredBackground(True)
   
    AddNavigationItem("10K", Colors.Blue, "likeb")
    AddNavigationItem("2K", Colors.Red, "comment")
    AddNavigationItem("Following", Colors.Yellow, "following")
End Sub

' define a single method to add an item
Sub AddNavigationItem(sTitle As String, clr As Int, res As String)
    ' the color here works when the isColoredBackground(true)
    ' when clicked, the color of the whole BottomNavigation turns into that
    Dim Item As BottomNavigationItem
    Item.Initialize(sTitle,clr,res)
    Navigation.addTab(Item)
End Sub

Hi, there is a way to rise every bottom click the onNavigationItemClick event? even though i already clicked it?

regards Paolo

 

[DonManfred]

even though i already clicked it?

The lib prevents to call the event twice.t only raise the event when the itemindex changes.

This is a wrap for this Github project.

It seems the author updated the lib and there are some new important features.

• disableShadow
• setItemActiveColorWithoutColoredBackground
• setTextActiveSize
• setTextInactiveSize
• setFont
• willNotRecreate
• setUpWithViewPager
• selectTab
• disableViewPagerSlide

@DonManfred would it be possible that you update the wrap?

(I tried to make a wrap with SLC by myself but I always get the error:
BottomNavigationView.java:10: error: package android.support.v4.content does not exist
import android.support.v4.content.ContextCompat;
and I don't know how to fix it.)

 

[DonManfred]

would it be possible that you update the wrap?

See Post #1

I´ve updated the lib to V1.1 using the newest github source...
I added a second sample to show the use of the ahviewpager... It is not using the color and imageresource arrays btw...

 

[fredo]

I´ve updated the lib

Thank you so much for your work @DonManfred.
It's a great help for the community to be able to build modern apps with B4X.

[DonManfred]

you forget

A) To add the resourcefolders to your project
B) to add the #additionalres line
C) both

 

[BarryW]

I

C) both

i alreader add those things

 

[MarcoRome]

I


i alreader add those things

This happen with library 1.1 ( Don also me have this error with Rel.1.1 )
If you try with library 1.0 work and try both example ( ButtonNavigationEx or ButtonNabvigationExViewPage ) will work without problem

Maybe Don have forget "new" folder Resource for Rel.1.1 ( in 2 example ButtonNabvigationExViewPage dont exist this folder and in first example ButtonNavigationEx is relative library 1.0 )

 

[JNG]

Will it be possible to use IconFonts in the navigation bar e.g.
FontAwesome / Material Icons ? if yes pl. help how.?

regards
jng

 

[DonManfred]

if yes pl. help how.?

It is not possible to set a Tpeface.
But you can create a Drawable by your own (using Fontawesome) and set the Drawable

 

[JNG]

Hi!

Little example will help me a lot I tried but unable to do.
