How to implement interaction of Navigation drawer and Bottom Navigation View?

Question

Java

I have created two navigation widgets - Navigation drawer and Bottom Navigation View. When switching to the Bottom Navigation View from the News fragment to the Search fragment, the News fragment is still indicated in the Navigation drawer (red arrow, it should be blue). How to fix it?

Answer 1

Attach an OnTabSelectedListener to the BottomNavigationView and change the color of the arrow depending on the flow tab.
