Custom TextSize of BottomNavigationView support android

Question

I am trying to change the textSize of BottomNavigationView from android support library 25.0.0

Answer 1

Add the TabTextStyle code inside the UpdateBarTextColor (this void exist in BottomBarPageRenderer)

 void UpdateBarTextColor()
    {
        if (_disposed || _bottomBar == null)
        {
            return;
        }
        //This is linked to styles.xml to set size of text
        _bottomBar.SetTextAppearance(Resource.Style.TabTextStyle);
        //Set color of text and icon in BottomNavBar
        _bottomBar.SetActiveTabColor(Element.BarTextColor.ToAndroid(Color.FromHex("#0094F0")));
        // The problem SetActiveTabColor does only work in fiexed mode // haven't found yet how to set text color for tab items on_bottomBar, doesn't seem to have a direct way
    }

And then add this inside the styles.xml:
