Background color change in BottomNavigationView

found an answer from this medium post

1. We need to use android:state_checked instead of android:state_enabled
2. within onNavigationItemSelected you need to use return true instead of return false.

and to set background, we cannot use android:color in <item>, we need to use android:drawable

So here how it looks xml file when you are setting it for app:itemTextColor and app:itemIconTint

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:color="@color/colorPrimaryDark" android:state_checked="true" />
    <item android:color="@android:color/white" android:state_checked="false" />
</selector>

and to set app:itemBackground selector

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/banner_white" android:state_checked="true"/>
    <item android:drawable="@drawable/banner_green" android:state_checked="false"/>
</selector>

Here banner_white and banner_green are pngs.
