Synchronize navigation box items with fragments

Question

I have a navigation box, and I also have a panel activity. Is it possible to go to any activity or fragment either in the navigation box or on the control panel? Therefore, when I view the activity of the panel. the navigation box does not synchronize with the current activity. So how to sync both?

Answer 1

In your activity of the navigation box you need to put this method, and in each fragment you need to return the index of the navigation elements. therefore, it is automatically synchronized with the navigation box.

public void NavigationFocus(int navItemIndex) { navigationView.getMenu().getItem(navItemIndex).setChecked(true); }
