A Xamarin.Forms control brings BottomNavigationView for bottom navigation on Android

This project is maintained by Naxam Co.,Ltd.
We specialize in developing mobile applications using Xamarin and native technology stack.

Looking for developers for your project?

BottomNavigationView is a new control since Android Support Design v25. This source code demonstrate the way to bring it into Xamarin.Forms.

However, BottomNavigationView is very limited from customizing, we have to employ library BottomNavigationViewEx as a patch.

In this code, we have

• A custom BottomTabbedPage
• A custom BottomTabbedRenderer

We could

• change color of background, text of the bar, each item
• chagne the height of the bar
• change text typeface

• BottomNavigationViewEx nuget

Install-Package Naxam.BottomTabbedPage

xmlns:naxam="clr-namespace:Naxam.BottomNavs.Forms;assembly=Naxam.BottomNavs.Forms"

BottomTabbedRenderer.BackgroundColor = new Android.Graphics.Color(23, 31, 50);
BottomTabbedRenderer.FontSize = 10;
BottomTabbedRenderer.IconSize = 20;
BottomTabbedRenderer.ItemTextColor = stateList;
BottomTabbedRenderer.ItemIconTintList = stateList;
BottomTabbedRenderer.Typeface = Typeface.CreateFromAsset(this.Assets, "HiraginoKakugoProNW3.otf");
BottomTabbedRenderer.ItemBackgroundResource = Resource.Drawable.bnv_selector;
BottomTabbedRenderer.ItemSpacing = 8;
BottomTabbedRenderer.ItemPadding = new Xamarin.Forms.Thickness(8);
BottomTabbedRenderer.BottomBarHeight = 80;
BottomTabbedRenderer.ItemAlign = BottomTabbedRenderer.ItemAlignFlags.Center;

BottomTabbedRenderer.MenuItemIconSetter = (menuItem, iconSource) => {
    var iconized = Iconize.FindIconForKey(iconSource.File);
    if (iconized == null)
    {
        BottomTabbedRenderer.DefaultMenuItemIconSetter.Invoke(menuItem, iconSource);

        return;
    }

    var drawable = new IconDrawable(this, iconized).Color(Color.White).SizeDp(20);

    menuItem.SetIcon(drawable);
};
