Can anyone help me how to fix this? I am new in Java.
When Bottom Navigation button is clicked, It should active the menu. But only home button is active all time. Clicking Others Button Changing the active color for 1 sec. After 1 sec Active color returns to 1st Button.

public class BottomNavigation {

    public static void setupBottomNavigation(final Activity activity, final BottomNavigationView bottomNavigationView) {

        bottomNavigationView.setOnItemSelectedListener(item -> {
            if (item.getItemId() == R.id.bookList) {
                startActivity(activity, BookListActivity.class);
                bottomNavigationView.setSelectedItemId(R.id.bookList); //This line is not working
                return true;
            } else if (item.getItemId() == R.id.home) {
                startActivity(activity, MainActivity.class);
                return true;
            } else if (item.getItemId() == R.id.writerList) {
                startActivity(activity, WriterActivity.class);
                return true;
            } else if (item.getItemId() == R.id.libraryList) {
                startActivity(activity, LibraryActivity.class);
                return true;
            } else if (item.getItemId() == R.id.contactUs) {
                startActivity(activity, ContactActivity.class);
                return true;
            } else {
                return false;
            }
        });
    }

    private static void startActivity(@NonNull Activity activity, Class<?> cls) {
        activity.startActivity(new Intent(activity.getApplicationContext(), cls));
        activity.overridePendingTransition(0, 0);
    }
}
