Hi Guys I found the solution to change the size of the text but its working i'm not sure this is correct way. Any way my issue has been resolved now follow my example really its working.
Add your style.xml file these lines:
<style name="BottomNavigationView">
<item name="itemTextAppearanceActive">@style/TextAppearance.BottomNavigationView.Active</item>
<item name="itemTextAppearanceInactive">@style/TextAppearance.BottomNavigationView.Inactive</item>
</style>
<style name="TextAppearance"/>
<style name="TextAppearance.BottomNavigationView"/>
<style name="TextAppearance.BottomNavigationView.Inactive">
<item name="android:textSize">12sp</item>
</style>
<style name="TextAppearance.BottomNavigationView.Active">
<item name="android:textSize">11sp</item>
</style>
Then add this line your Bottom Navigation view:
style="@style/BottomNavigationView"
That's all really its working
