BottomNavigationView

I am trying to implement BottomNavigationView in my app but getting errors.

To use a BottomNavigationView:

Add them to your layout:

<android.support.design.widget.BottomNavigationView
    android:id="@+id/bottom_nav_view"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:menu="@menu/activity_main_bottom_actions" />

So use java to manipulate:

import android.support.design.widget.BottomNavigationView;
// first import
...

BottomNavigationView a;

@Override protected void onCreate(Bundle sis) {
    super.onCreate(sis);
    setContentView(R.layout.my_view);
    
    a = findViewById(R.id.bottom_nav_view);
}

In your case you’re missing the correct import of the bottom nav view as explained by @EduApps. Alternatively, pressing and holding on an error will prompt a check mark on Aide’s toolbar to fix your error if it is fixable.
