On tab change LastSelectedIndex should be update to the previous tab but it only updates for the first time only and not the subsequent calls.

We need gain support ofr this event

I wanna use Icon only
But, when i remove title, blank space is appear at title location

How I set icon only?

The first time opening app => exception : android.widget.FrameLayout cannot be cast to android.widget.ImageView

Bellow my home page xaml :

<naxam:BottomTabbedPage xmlns="http://xamarin.com/schemas/2014/forms" xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"

I get this error when I try to install your package in a newly created Xamarin.Forms project.
Could not install package 'Naxam.BottomTabbedPage 0.2.0.2'. You are trying to install this package into a project that targets '.NETPortable,Version=v4.5,Profile=Profile111', but the package does not contain any assembly references or content files that are compatible with that framework. For more information, contact the package author.

What can I do to install your package?

is there a way to change the font size of the title when tab is selected?

Hello,

I would like to know if there is a way to use the "default" font type for the Title of the tabs?

For me, the "default" font type is the one that we can found in the Android Bottom Navigation View, like described in this blog.

Regards,

I got a switch page problem.
When switch page, it always pop to root, so I downloaded demo for test.
And I found out demo has same problem and it crash.

Main cause is when switch page
public static void SwitchPage(this BottomTabbedRenderer renderer, IMenuItem item)
would be called twice.

anybody tried for uwp and ios? i dont see any information that it support these 2

ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
x:Class="DhruvTL.Pages.TourLandingPage"
NavigationPage.HasNavigationBar="false">

There is no animation when changing the tabs, (Left or Right) slide is a must in my opinion.

Hi, I'm using the component, but I have a problem.

After calling the screen in a navigation it does not display the title in the View. Is it possible to display using some property?

I am using Xamarin.Forms and testing in IOS.

The View title is used only in the menu. Thank you

hi guys!

I am getting the stacktrace below when trying to navigate between tabs.

Hello. I implemented your code and it works when the page is a BottomTabbedPage.
I want to use it inside a MasterDetailPage, so I have side menu and bottom menu, which is what i'm doing BottomNavigationBarXF (that package is outdated).

When I try to set BottomTabbedPage as MasterDetailPage.Detail I get this error:

I've noticed this package has been updated but cannot find any changelogs about what has been updated. Have new features been added? have bugs been fixed?

It would be nice if you could add some kind of a change log so we are up to date :)

I have a project and I use bottomtabbedpage-xamarin-forms plug-in in my project.
I use Xamarin.Forms Version 2.5.0.280555.
It is fine.
But if I update grade Xamarin.Forms to higher version, I got an problem.
The problem is if I switch tab page then switch back to previous tab page.
The previous tab page would reload.
For example, I switch to page3 from page1, and then switch back to page1.
Page1 would reload.
I tried 3.0.0.561731 got the same result.
My test project

I don't if this caused by bottomtabbedpage-xamarin-forms or by Xamarin.Forms.

Thanks.

since Xamarin.Android.Support.Design 25.4.0.1 doesn't provide the BottomNavigationMenu
you have to downgrade your Xamarin.Android.Support.Design to 25.3

Suddenly Getting this error on build:
Can not resolve reference: Xamarin.Android.Support.ViewPager, referenced by Naxam.Ittianyu.BottomNavExtension. Please add a NuGet package or assembly reference for Xamarin.Android.Support.ViewPager, or remove the reference to Naxam.Ittianyu.BottomNavExtension
visual studio 2019
Naxam.BottomTabbedPage 0.3.0.2
Xamarin.Android.Support.ViewPager 28.0.0.1 is also installed

when one of children of BottomTabbedPage is xamarin TabbedPage whith two tabs for example, every time I switch tabs made by BottomTabbedPage and returning to child tab with xamarin TabbedPage - sliding indicator animation when trying to switch tabs in TabbedPage by clicking on tab name not working first time, and then go to normal behavior unless I again switch tabs made by BottomTabbedPage.

How can I fix it?

TabbedPage has performance issue because That load entire tab view when init
And in android, several ways solve this problem like using 'setUserVisibleHint'

And Can update this performance issue in this project??

Hello,

Sorry to bothering you:
I think there is an issue on the SizeUtils.cs

I got this:

My Setup

 void SetupBottomTabs()
        {
            BottomTabbedRenderer.FontSize = 10;
            BottomTabbedRenderer.IconSize = 20;
            BottomTabbedRenderer.ItemSpacing = 0;
            BottomTabbedRenderer.BottomBarHeight = 56;
            BottomTabbedRenderer.ItemAlign = ItemAlignFlags.Center;
            BottomTabbedRenderer.MenuItemIconSetter = (menuItem, iconSource, selected) =>
            {
                var iconized = Iconize.FindIconForKey(iconSource.File);
                if (iconized == null)
                {
                    BottomTabbedRenderer.DefaultMenuItemIconSetter.Invoke(menuItem, iconSource, selected);
                    return;
                }
                var drawable = new IconDrawable(this, iconized).Color(Color.White).SizeDp(20);
                menuItem.SetIcon(drawable);
            };
        }

Or have you got an idea on what I'm doing wrong?

Regards,

In your blog post you show different styles, such as one with no text:

How do I use this style? I do not see options for this in BottomTabbedRenderer.

Thanks.

where BasePage
public class BasePage : ContentPage
{

i am using color icon with black backgroud
problem while showing icon

Is it possible to set badges with this solution? I found it is exposed in bottomnavigationviewex but I'm not seing how to access the instance.

Is there a way I pull it out similar to
FindViewById<BottomNavigationViewEx>(Resource.Id.bnve);

https://github.com/NAXAM/bottomnavigationviewex-android-binding/blob/72c6718d47f31ecd5f53cd14d51f094ade89694b/BottomNavExtentionExample/code/BadgeViewActivity.cs

Hi this issue i to track the support for .NET Standard and avoid the warning when include the package in to .NET Standard xamarin forms project.
warning NU1701: Package 'Naxam.BottomTabbedPage 0.1.0.1' was restored using '.NETFramework,Version=v4.6.1' instead of the project target framework '.NETStandard,Version=v2.0'.

Hello,

Is it possible to get an event when tab is clicked?

I need to do this: when i am on certain tab, and i click same tab again, i'd like the page to pop to root.

Looks like iOS supports this feature by default, and i need to do this on Android.

or is there any way to achieve this? Thank you.

Maybe...looks already have shadow
But wanna more customize

Ps. Your package is best for me thanks very much

Hi.

How can i show/hide the tab bar when keyboard appears?

Is it possible to move the Snackbar above Bottom Navigation bar.

I have created the snackbar like this

var view = ((Activity)Forms.Context).FindViewById(Android.Resource.Id.Content); var snack = Snackbar.Make(view, message, duration); if (actionText != null && action != null) snack.SetAction(actionText, action); snack.Show();

But the snackbar overlaps the bottom bar.

First,update Xamarin.Forms to 3.0.0.446417.
While I am setting App.Current.MainPage = new NavigationPage(...) in BottomTabbedPage leads the App to crash.

It's a funny thing, the method "Dispose(bool disposing)" in BottomTabbedRenderer would be called twice, so that cause the crash.
