Your usage is wrong!

R.id.bottom_navigation_view_linear is of the type BubbleNavigationLinearView or it can be of type BubbleNavigationConstraintView

Use like this

BubbleNavigationLinearView bubbleNavigation = findViewById(R.id.bottom_navigation_view_linear);
bubbleNavigation.setNavigationChangeListener(new BubbleNavigationChangeListener() {
        @Override
        public void onNavigationChanged(View view, int position) {
            switch (view.getId()){
                case R.id.l_item_search:
                    Intent in=new Intent(getBaseContext(),Secondactivity.class);
                    startActivity(in);
                    break;
            }
        }
