Custom TextSize of BottomNavigationView support android

Question

Answer 1

You can change BottomNavigationView text appearance by defining your own styles for Component Attributes itemTextAppearanceActive and itemTextAppearanceInactive. By default they have textAppearanceCaption check section Theme Attribute Mapping in the docs Bottom Navigation.

styles.xml

• Next, Change Text Color selected and icon:
  Just Create bottom_nav_icon_color_selector & bottom_nav_text_color_selector on drawable to edit default value.

• For change icon color - bottom_nav_icon_color_selector.xml

• For change text color - bottom_nav_text_color_selector.xml

• Note : @color/colorIconInActive is a color disable/inactive, you can set this color in your res-values-colors
• Finish, try to see, your navigation bottom. color icon and text will be change.
